The Hidden Dangers of Soot in Your Sacred Space
That fine black residue coating your candle holders and bathroom surfaces isn’t just a cleaning nuisance—it’s a complex mixture of carbon particles, partially burned hydrocarbons, and potentially toxic compounds. In the confined, humid environment of a bathroom, these particles behave differently than in open living spaces, creating unique challenges for both your health and home maintenance.
Why Bathrooms Are Particularly Vulnerable
Bathrooms present a perfect storm for soot deposition. High humidity causes particles to become sticky and adhere aggressively to tile, grout, and painted surfaces. The typically small square footage concentrates particle density, meaning you inhale a higher concentration compared to larger rooms. Poor ventilation during a relaxing soak traps these particles, turning your sanctuary into a low-level exposure chamber. Unlike living rooms where air circulates freely, your bathroom’s closed-door, steam-filled environment amplifies every emission from an improperly formulated candle.
Health Implications of Candle Soot
Inhaled soot particles penetrate deep into lung tissue, triggering inflammatory responses and potentially exacerbating asthma or allergies. The polycyclic aromatic hydrocarbons (PAHs) carried on these particles are known carcinogens, while volatile organic compounds (VOCs) released during incomplete combustion can cause headaches, dizziness, and respiratory irritation. In a bathroom setting where you’re already breathing more deeply during relaxation, your exposure risk increases significantly. Clean-burning candles aren’t just about aesthetics—they’re about protecting your respiratory health during your most vulnerable moments of unwinding.
Decoding “Soot-Free”: Marketing vs. Reality
The term “soot-free” exists in a regulatory gray area, with no standardized definition or certification requirement. Manufacturers can legally use this label if their candles produce minimal visible soot under ideal conditions, but “minimal” and “ideal” are subjective. Understanding the physics of combustion reveals that no candle can be 100% soot-free—complete combustion requires perfect fuel-to-air ratios that rarely exist in real-world settings. What separates quality candles from problematic ones is their ability to approach this theoretical ideal through superior materials and engineering.
True low-soot performance depends on three interdependent factors: wax purity, wick design, and burn environment. A candle might burn cleanly in a draft-free lab but produce significant soot in your bathroom where steam, air currents from ventilation fans, and proximity to water create dynamic conditions. The best tea lights are designed with these real-world variables in mind, using materials that maintain stable combustion even when conditions aren’t perfect.
Wax Chemistry: The Building Blocks of Clean Combustion
The wax itself determines roughly 70% of a candle’s soot potential, serving as the primary fuel source that must vaporize evenly and combust completely. Not all waxes are created equal, and the molecular structure directly impacts how cleanly your candle burns in humid bathroom conditions.
Soy Wax: The Natural Standard
Hydrogenated soybean oil creates a dense, slow-burning wax with a relatively low carbon content. Its natural composition includes fewer aromatic hydrocarbons than petroleum-based waxes, resulting in cleaner baseline combustion. The key lies in the wax’s melting point—quality soy tea lights use formulations that melt between 120-125°F, creating an optimal pool temperature that fully vaporizes fuel without overheating. However, soy wax’s hygroscopic nature means it absorbs moisture from humid bathroom air, which can affect burn quality if not properly formulated with stabilizers. Look for non-GMO, pesticide-free soy sources, as agricultural residues can contribute to incomplete combustion.
Beeswax: The Premium Purifier
With the highest melting point of common candle waxes (145-150°F), beeswax burns hotter and brighter, creating stronger convection currents that pull more oxygen to the flame. This natural draft effect promotes more complete combustion, while the wax’s inherent honey scent requires no synthetic fragrances. The molecular structure includes long-chain alcohols and acids that burn exceptionally clean, but this performance comes at a cost—beeswax tea lights typically command premium prices. The golden color indicates the presence of pollen and propolis, which can add subtle variations to burn performance. For bathroom use, ensure the beeswax is filtered to remove debris that could clog wicks.
Coconut Wax: The New Frontier
Derived from cold-pressed coconut meat, this wax boasts the cleanest burn profile of all natural options, with virtually zero soot under proper conditions. Its low melting point (100-110°F) allows for rapid scent throw and quick pool formation, but requires precise wick sizing to prevent the flame from drowning in melted wax. Coconut wax’s high oil content creates a luxurious scent diffusion perfect for aromatherapy baths, but its softness demands rigid containers. The wax’s natural resistance to moisture makes it particularly suitable for humid bathroom environments, though its premium cost and limited availability restrict widespread adoption.
Paraffin: The Controversial Option
Refined petroleum paraffin can burn cleanly when highly purified, but most mass-market tea lights use lower-grade slack wax containing aromatic compounds that readily produce soot. The carbon content is simply higher, and the molecular structure includes more complex hydrocarbons that struggle to combust completely. While some premium paraffin blends incorporate soot inhibitors and advanced wick systems, the risk-to-reward ratio rarely justifies their use in intimate spaces like bathrooms where air quality matters most. If considering paraffin, demand detailed refinement specifications and independent lab testing results.
Wick Engineering: Where the Magic Happens
The wick is the engine of combustion, controlling fuel delivery rate, flame stability, and oxygen access. A perfectly engineered wick can make mediocre wax burn reasonably clean, while a poor wick will ruin even the purest beeswax.
Cotton vs. Wood Wicks
Braided cotton wicks remain the industry standard for tea lights due to their predictable capillary action and consistent burn rate. The best versions use long-staple cotton with tight braiding that prevents “mushrooming”—that bulbous carbon buildup at the wick tip that rains soot into the wax pool. Wood wicks create a mesmerizing crackling ambiance and broader flame geometry that can improve combustion efficiency, but their performance varies dramatically with humidity. In steamy bathrooms, wood wicks may absorb moisture, altering their burn characteristics mid-session. They also require more precise container depth-to-width ratios to maintain proper fuel flow.
The Importance of Wick Sizing
Wick diameter must match the tea light’s wax volume and container diameter precisely. Too small, and the wax pool won’t reach the edges, causing tunneling and wasted fuel. Too large, and the flame consumes fuel faster than complete combustion allows, generating copious soot. Quality manufacturers use wick sizing charts based on wax type, fragrance load, and container dimensions. For bathroom tea lights, slightly undersized wicks often perform better because the humid air already reduces oxygen availability—counterintuitive but crucial for clean burning.
Core Materials: Zinc, Paper, or Nothing?
Cored wicks provide rigidity, preventing the wick from flopping over as wax melts. Zinc cores offer excellent rigidity but can produce trace metal emissions if the wire overheats. Paper cores burn cleaner but may not stay upright through the entire burn cycle. Coreless wicks, made from rigidized cotton, represent the cleanest option but require precise wax formulations to maintain structure. For soot-sensitive environments, coreless or paper-cored wicks outperform zinc, especially in shorter-duration tea lights where structural demands are lower.
Fragrance Load: Balancing Aroma and Clean Burn
Scent transforms a simple bath into a therapeutic experience, but fragrance oils are complex chemical cocktails that can dramatically impact soot production. The challenge lies in achieving sufficient scent throw without overloading the wax with compounds that resist complete combustion.
Essential Oils vs. Synthetic Fragrances
Pure essential oils contain volatile organic compounds that vaporize readily at wax pool temperatures, requiring minimal heat to release aroma. This low thermal demand preserves the flame’s energy for complete wax combustion. However, essential oils have lower flash points—some below 140°F—creating fire hazards if overloaded. Synthetic fragrances offer more stable performance and broader scent palettes but often include phthalates and other fixatives that increase soot. The cleanest approach uses phthalate-free synthetic fragrances specifically formulated for low-soot applications, or essential oils at precisely calculated load rates (typically 6-8% for tea lights).
Phthalate-Free Formulations
Phthalates, used to extend fragrance longevity, have high boiling points that cause them to pool in the wax rather than vaporize cleanly. When they do eventually combust, they produce dense, sticky soot that adheres aggressively to bathroom surfaces. Premium low-soot candles explicitly state “phthalate-free” and use alternative fixatives like dipropylene glycol or natural isolates. These alternatives vaporize more completely, though they may reduce scent longevity. For a 30-45 minute bath, this trade-off favors clean air over extended fragrance release.
Burn Dynamics: Time, Temperature, and Wax Pool
Understanding how tea lights evolve during their burn cycle helps you select products that maintain clean combustion from first light to final flicker. The relationship between burn time, pool temperature, and wax consumption rate determines real-world soot output.
Optimal Burn Time for Tea Lights
Standard tea lights burn 3-5 hours, but for bathtub relaxation, you’re typically using them for 30-90 minutes. This partial burn cycle creates unique challenges—candles perform differently during warm-up (first 15 minutes) and steady-state phases. Quality bathroom tea lights are engineered to reach optimal combustion temperature within 5-7 minutes, minimizing the soot-rich warm-up period. Look for specifications mentioning “rapid pool formation” or “optimized for sessions under 2 hours.” These products use lower melting-point waxes and precisely calibrated wicks to skip the dirty warm-up phase.
The Full Melt Pool Imperative
A full melt pool—where liquid wax reaches the container’s edges—should form within 1-2 hours for standard tea lights. Incomplete pools indicate under-wicking, which leads to tunneling and eventually drowns the wick, causing it to sputter and soot. Conversely, pools that form too quickly suggest over-wicking, where excessive fuel flow overwhelms the flame’s combustion capacity. For bathroom use, aim for tea lights that achieve full pool at the 45-minute mark, aligning perfectly with average soak times while maintaining clean burn throughout.
Container Considerations: Beyond Simple Holders
The humble metal cup holding your tea light plays a surprisingly critical role in soot production. Material, shape, and finish all influence heat retention, air flow, and combustion stability.
Heat-Resistant Materials
Aluminum cups dominate the market due to cost, but they conduct heat away from the wax pool too efficiently, forcing the flame to work harder and consume more fuel to maintain temperature. This increased fuel demand raises soot potential. Steel cups, though heavier, retain heat better, maintaining optimal pool temperature with less flame stress. Premium options use double-walled designs that insulate the wax while keeping exterior surfaces cool enough for safe handling. For bathroom use, avoid cups with painted interiors—high heat can vaporize paint compounds, adding to your air quality concerns.
Recessed vs. Exposed Designs
Recessed cups, where the rim sits above the wax line, protect the flame from drafts but can restrict oxygen flow, creating a oxygen-starved burn that soots heavily. Exposed designs allow better air circulation but leave flames vulnerable to bathroom ventilation currents. The optimal compromise features a slightly flared rim—just 2-3mm above the wax—that shields the flame while allowing sufficient oxygen access. Some advanced designs incorporate micro-perforations near the base to create passive air intake, improving combustion without visible draft holes.
Reusable vs. Single-Use
Reusable glass or ceramic tea light holders offer aesthetic appeal and reduce waste, but they change the thermal dynamics completely. The additional mass absorbs heat that should warm the wax, extending the soot-producing warm-up phase by 10-15 minutes. If using reusable holders, pre-warm them with hot water (dried thoroughly before candle insertion) to jump-start the pool formation. Single-use metal cups are engineered for optimal thermal performance, making them the cleaner-burning choice despite environmental drawbacks.
Colorants and Additives: Invisible Culprits
Those beautiful colored candles might match your bathroom décor, but dyes rank among the top soot contributors. The pigments and carriers used to tint wax fundamentally alter combustion chemistry.
The Soot Impact of Dyes
Candle dyes consist of dye solids suspended in carrier oils. These solids don’t vaporize—they remain as particulate matter that either settles in the wax pool or gets drawn into the flame, where they partially combust into colored soot. Darker dyes require higher concentrations, exponentially increasing particulate load. In the humid bathroom environment, these colored particles become especially adhesive, staining grout and painted surfaces. For truly clean burning, embrace the natural creamy color of soy or beeswax. If you must have color, limit it to the container exterior, never the wax itself.
Stabilizers and UV Inhibitors
Natural waxes oxidize over time, becoming brittle and developing surface bloom. Manufacturers add stabilizers to extend shelf life, but these compounds—often petroleum-derived—can increase soot. UV inhibitors prevent fading but introduce additional chemicals to the combustion mix. For bathroom tea lights that you’ll use within 6-12 months of purchase, these additives offer minimal benefit while compromising air quality. Look for “no additives” or “pure wax” labeling, and store candles in dark, cool places to eliminate the need for chemical stabilizers.
Industry Certifications and What They Prove
While “soot-free” lacks regulation, several third-party certifications provide measurable benchmarks for clean burning and safety. Understanding these standards helps cut through marketing noise.
IFRA Compliance
The International Fragrance Association (IFRA) sets maximum safe usage levels for fragrance components. While primarily focused on skin safety, IFRA compliance indirectly supports clean burning by limiting high-soot-potential compounds. Look for candles stating “IFRA 49th Amendment Compliant,” indicating adherence to the latest standards. However, compliance doesn’t guarantee low soot—only that fragrance components stay within established safety thresholds.
RIFM Standards
The Research Institute for Fragrance Materials conducts toxicological assessments of raw fragrance materials. Candles using RIFM-evaluated ingredients have been screened for respiratory irritants, but the evaluation doesn’t encompass combustion byproducts. It’s a valuable data point but incomplete for soot assessment. Combine RIFM certification with other indicators for a fuller picture.
Air Quality Certifications
The most relevant certifications come from air quality organizations. GREENGUARD Gold certification (formerly GREENGUARD Children & Schools) tests products for over 360 VOCs and particulate emissions in simulated real-world conditions. For bathroom use, this represents the gold standard, ensuring the candle won’t significantly impact indoor air quality. Few tea lights achieve this due to testing costs, but those that do represent the cleanest options available.
Price Points and Value: What Should You Expect to Pay?
Clean-burning technology costs more, but the price spectrum reveals important quality differentiators. Understanding cost drivers helps you invest wisely rather than overspending on marketing.
Cost Per Hour of Burn
Calculate value by dividing package price by total burn hours. Budget tea lights ($0.10-0.20 each) typically use paraffin blends and zinc-cored wicks, making them unsuitable for bathroom use. Mid-range options ($0.30-0.50 each) offer clean-burning soy or coconut wax with cotton wicks—this is the sweet spot for most users. Premium beeswax or coconut tea lights ($0.75-1.50 each) deliver superior performance but diminishing returns for short bath sessions. For regular use, mid-range products provide 90% of the clean-burning benefits at half the cost of premium options.
Bulk Buying Strategies
Purchasing 50-100 count bags reduces per-unit cost by 30-40%, but storage becomes critical. Wax degrades over time, and bulk purchases risk using degraded candles that soot more. Only buy bulk quantities you’ll use within 6 months. Split purchases with friends or family to maximize savings without compromising freshness. Avoid warehouse club multi-packs unless you can verify manufacturing dates—sitting in distribution centers for a year negates any quality advantages.
Storage and Shelf Life: Maintaining Quality
Even the best-engineered tea light will soot heavily if stored improperly. Wax is chemically active, slowly oxidizing and absorbing environmental contaminants that disrupt clean combustion.
Temperature and Humidity Control
Store tea lights at 60-75°F in airtight containers. Temperatures above 80°F cause wax to soften and release volatile compounds that later contribute to soot. Below 55°F, wax contracts, potentially cracking and creating air pockets that cause uneven burning. Humidity above 60% lets wax absorb water, which then flashes to steam during burning, destabilizing the flame. Use silica gel packets in storage containers, especially in naturally humid bathrooms. Never store candles under sinks or in medicine cabinets where moisture concentrates.
Packaging Integrity
Original packaging protects candles from dust and contaminants that clog wicks and disrupt fuel flow. Once opened, transfer unused candles to sealed glass jars rather than plastic bags, which can off-gas chemicals into the wax. If candles develop a powdery white “bloom,” it’s harmless crystallization but indicates aging—use these sooner rather than later, as they’re past peak performance.
Setting Up Your Bathroom Sanctuary: Placement and Arrangement
Strategic positioning maximizes ambiance while minimizing soot exposure. Every bathroom layout presents unique airflow patterns that affect candle performance.
Ventilation Management
Close bathroom doors and turn off exhaust fans 5 minutes before lighting candles. This creates still air that supports stable flame geometry. After your bath, relight the fan and open doors to clear humidity, but never blow out candles—snuff them to prevent soot surge. For bathrooms with poor ventilation, crack a window 1-2 inches instead of using the fan, creating gentle crossflow that won’t disrupt flames. Position candles at least 3 feet from active ventilation grates to avoid direct drafts.
Proximity to Water Sources
Steam from your bath creates micro-currents that can tilt flames, causing uneven heating and soot. Place candles on dry surfaces at tub level or slightly above—never on the tub rim where water splashing can create sudden cooling events. The ideal distance is 2-4 feet from the tub edge, close enough for ambiance but protected from direct steam columns. Use floating candle holders on the water surface only with specially designed waterproof tea lights; standard metal cups will rust and potentially short-circuit, creating safety hazards.
Reflective Surfaces and Light Optimization
White tile and mirrors amplify candlelight beautifully but reflect heat back onto candles, potentially overheating wax pools. This thermal feedback loop increases fuel vaporization rate beyond the flame’s combustion capacity. Offset candles 6-8 inches from reflective surfaces, or place a small piece of matte ceramic between candle and wall to absorb excess radiant heat. Group candles in odd numbers (3, 5, or 7) spaced 4-6 inches apart—this creates overlapping convection currents that stabilize individual flames while producing more dramatic lighting effects.
Safety Protocols for Wet Environments
Bathrooms combine water, electricity, and open flame—a trifecta of hazards requiring strict safety discipline. Clean-burning candles reduce air quality risks but don’t eliminate fire and electrical dangers.
The Non-Negotiable Rules
Never leave burning candles unattended, even for “just a moment.” Keep a small metal lid or snuffer within arm’s reach to extinguish flames without the soot surge caused by blowing. Position candles away from towels, curtains, and bath products—minimum 12-inch clearance in all directions. Use only stable, non-slip surfaces; a candle knocked into bathwater can cause severe burns and creates a slipping hazard from wax film. Install a battery-operated smoke detector in the bathroom, as standard wired units can short-circuit in humid conditions. Test it monthly, and never disable it for ambiance.
What to Do When Things Go Wrong
If a candle flame grows taller than 1 inch or starts smoking excessively, extinguish it immediately—this indicates wick failure or wax contamination. For wax spills on tile, let it cool completely before scraping with a plastic putty knife; hot water spreads the stain. Never use chemical cleaners on wax spills near candles, as residue can contaminate future burns. If you experience dizziness or headache during a bath, extinguish candles and ventilate immediately—this could indicate carbon monoxide from incomplete combustion, a rare but serious risk with poor-quality candles in sealed bathrooms.
Troubleshooting Your Burn Experience
Even premium tea lights can behave unpredictably in bathroom conditions. Understanding failure modes helps you diagnose and correct issues without abandoning clean-burning principles.
When Your Candle Won’t Stay Lit
Repeated extinguishing usually signals wick clogging from moisture or dust. Try trimming the wick to 1/4 inch before relighting—this removes the contaminated portion. If the problem persists, the wax may have absorbed too much humidity; move future candles to drier storage. In extreme cases, gently warm the candle with a hair dryer on low for 30 seconds before lighting to drive off surface moisture. Never relight a candle that has extinguished itself more than twice; the wax pool contains combustion byproducts that will increase soot on subsequent attempts.
Addressing Tunneling Issues
Tunneling—where wax walls remain unmelted around a deep pool—creates wasted wax and eventual wick drowning. This occurs when wicks are undersized or when candles are extinguished before achieving full pool. For partially tunneled candles, “hug” the warm wax walls inward after extinguishing while the wax is still pliable. To prevent recurrence, ensure your first burn lasts until the pool reaches the edges (usually 1-2 hours), establishing a “memory” for subsequent burns. In bathroom settings, avoid extinguishing candles before the 45-minute mark unless safety demands it.
Extinguishing Problems and Solutions
Blowing out candles creates a soot plume that can deposit more residue in one second than an hour of clean burning. Always use a snuffer or place a metal lid directly on the cup to starve the flame of oxygen. If you must blow, hold a spoon above the flame to deflect the soot downward into the wax pool rather than into your bathroom air. For candles that continue smoking after extinguishing, dip the wick into the melted wax pool using a toothpick, then immediately straighten it—this coats the wick tip, preventing afterglow and smoke.
Environmental and Ethical Considerations
Your pursuit of clean air shouldn’t compromise planetary health. The candle industry’s environmental impact extends beyond wax type to sourcing, manufacturing, and packaging practices.
Sustainability in Wax Sourcing
Soy wax often comes from large-scale monoculture operations with heavy pesticide use and deforestation impacts. Look for “certified sustainable” or “Rainforest Alliance” soy sources. Beeswax should be sourced from apiaries practicing ethical beekeeping—avoid “filtered” beeswax that may come from industrial honey operations where bees are overworked. Coconut wax’s rapid renewability makes it environmentally superior, but verify fair-trade sourcing to ensure ethical labor practices. Some innovative companies now use upcycled wax from industrial food production, creating circular economy products with minimal environmental footprint.
Packaging Waste Reduction
Individual tea light wrappers create surprising waste. Choose bulk-packaged candles in recyclable cardboard with minimal plastic windows. Some brands offer refill programs where you return spent metal cups for reuse—slightly more expensive but dramatically reduces waste. For ultimate sustainability, purchase wax pellets and pre-tabbed wicks to make your own tea lights in reusable silicone molds. This eliminates packaging waste entirely and lets you control every ingredient for maximum clean-burning performance.
Frequently Asked Questions
1. Can I really get a completely soot-free burn in my humid bathroom?
While “soot-free” is technically impossible, you can achieve near-zero visible soot by using high-quality coconut or beeswax tea lights with cotton wicks, maintaining still air conditions, and keeping burn sessions under 90 minutes. The key is controlling humidity around the candles—close doors and turn off ventilation 5 minutes before lighting to create stable combustion conditions.
2. Why do my tea lights soot more in winter than summer?
Cold ambient temperatures make wax harder to melt, forcing flames to burn hotter and consume more fuel to maintain the pool. This increased fuel flow often exceeds complete combustion capacity. Pre-warm your bathroom to at least 68°F before lighting candles, and store tea lights at room temperature rather than in cold bathrooms or garages.
3. Are unscented candles always cleaner-burning than scented ones?
Not necessarily. A well-formulated scented candle using phthalate-free fragrances at 6-8% load can burn cleaner than a poor-quality unscented candle with contaminated wax or improper wick sizing. However, fragrance-free candles eliminate one variable, making them more predictable for soot-sensitive users. The cleanest option is pure beeswax, which needs no added scent.
4. How can I tell if a candle is producing soot before I see black marks?
Hold a clean white plate 6 inches above a burning candle for 30 seconds. Any discoloration indicates soot production. Also, watch for a dancing, flickering flame taller than 1 inch, or a visible smoke trail from the flame even when still. A truly clean burn shows a steady, teardrop-shaped flame with no visible emissions.
5. Is it safe to burn tea lights in a closed bathroom without ventilation?
For short sessions (30-45 minutes) with clean-burning candles, yes—this actually improves combustion stability. However, you must monitor for headache, dizziness, or eye irritation, which signal air quality issues. Always crack a window or run ventilation for 5 minutes after extinguishing candles to clear humidity and any residual combustion byproducts.
6. Can I reuse the metal cups from spent tea lights?
Yes, but clean them thoroughly to remove soot residue that could contaminate new wax. Wash with hot, soapy water, then wipe with rubbing alcohol. Avoid using dented cups, as irregular shapes disrupt airflow and cause uneven burning. Never refill cups more than twice, as metal fatigue can lead to leaks or structural failure.
7. Why do some of my tea lights burn cleanly while others from the same package soot heavily?
This inconsistency usually indicates manufacturing quality control issues—wick placement variance, wax density differences, or fragrance distribution unevenness. It can also result from storage conditions where some candles absorbed more moisture than others. Purchase from brands with batch numbers and quality guarantees, and report consistent issues to the manufacturer.
8. Are LED tea lights a viable alternative for true clean air?
Modern LED tea lights with flicker effects provide ambiance without any combustion concerns, making them ideal for those with severe respiratory sensitivities. However, they lack the subtle scent diffusion and authentic warmth of real flames. For the best of both worlds, use one real beeswax candle for aromatherapy benefits and supplement with LED lights for additional ambiance.
9. How do I clean soot marks from bathroom surfaces without spreading them?
Use a dry microfiber cloth to gently wipe loose soot without water, which can drive particles into porous grout. Follow with a solution of 1 part white vinegar to 3 parts water on non-porous surfaces only. For stubborn stains on painted walls, use a melamine foam eraser very gently to avoid removing paint. Always test cleaning methods in an inconspicuous area first.
10. What’s the single most important factor when choosing bathroom tea lights?
Wick quality outweighs all other factors. A properly engineered cotton wick with correct sizing for the wax type and container will burn cleanly even if other elements are imperfect. Look for tightly braided, coreless wicks with visible fiber uniformity. When in doubt, contact manufacturers directly about their wick specifications—reputable companies will gladly share this technical detail.
