![]() ![]() Under normal operation, the tip of the candle wax is just hot enough to melt a small pool of wax but not hot enough to boil it, putting it at between 50☌ and 370☌. The most obvious is that the heat of the flame, normally drawn up and away because hot air’s less dense than cold air, will flow directly into the tip of the candle. Candle flames are such common sights that we often overlook their complicated anatomy look at one closely and you’re likely to see a number of features, from the blue glow at the bottom to the tapering of the tip, that everybody recognizes but few people could actually explain if asked.Įxplaining all of candle physics would take a textbook, but for this question, we only need to think about things that change when the candle is turned upside down, which simplifies the problem a lot. They illustrate a slew of different chemical and physical effects so elegantly that the famous physicist Michael Faraday gave a series of lectures on candles using them to demonstrate effects from from turbulence to buoyancy to blackbody radiation and to explain the chemistry of fire. Their simplicity is deceptive burning candles are actually pretty complex systems with many interacting parts and processes. To take a guess, we need to understand how candles work. In that spirit, what would happen if you burned a candle upside-down? While candles do require ventilation so that they do not exhaust the oxygen in the room, they should also be kept away from drafts in order to ensure a controlled burn.As every child knows, sometimes it’s fun to do something exactly wrong. Strong drafts could also blow nearby lightweight items into the flame where they could catch fire. ![]() Making sure that you place the candle away from any drafts, vents, fans or air currents will prevent rapid and uneven burning, avoid flare-ups and sooting. Make sure your candle is free of wick trimmings, matches and debris at all times as these things can catch fire. It is also important to make sure the holders are set on flat, stable surfaces to minimise the chance they will tip over. You should be especially careful with night lights and tea lights, as they can get hot enough to melt plastic The holder should be heat resistant, sturdy, and large enough to catch any drips or hot melted wax.Īlways put candles including ones already in containers on a heat resistant surface. We recommend using a candle holder specifically designed for candle use. Place the candle on a stable, heat-resistant surface. There should be at least 1m between the candle flame and the surface above it. Keep burning candles away from furniture, curtains and drapes, bedding, carpets, books, paper, flammable decorations, clothing, hair etc.ĭon’t place your candles under shelves as there is a lot of heat above a burning candle. Make sure that there is nothing flammable in the vicinity of your scented candle. Place the candle away from anything flammable. Burn candles in a well-ventilated room.ĭon’t burn too many candles in a small room or in a “tight” home where air is limited. Long or crooked wicks can cause uneven burning, dripping or flaring. Keep candles out of the reach of children and pets.īefore you light a candle for the first time, or relight a used candle, you must trim the wick down to about 5mm.Never burn a candle on or near anything that might catch fire. ![]()
