Wax is mostly a blend of long straight-chain hydrocarbons (alkanes, also called olefins).  It is a waxy (ha ha) solid at room temperature, and stable.  When you light a candle, the flame on the wick begins to melt some of the wax.  The liquid wax is drawn up the wick, where it burns, being converted to carbon dioxide, water, light, and heat.  Any other chemical compounds, such as fragrances, are also released at this time, usually from the pool of molten wax around the wick.

Like most things, an important detail is *approach*—the LEAST painful way to accomplish ANY painful thing is to MINIMIZE your EXPOSURE to the painful aspect! ;)\n\nTo put out the candle with your fingers, bring them in from BELOW the flame, be SURE they are WET (WETTER the BETTER), and then *POOF* SNIP out the FLAME! :)\n\nYes, it might sting a bit, but given that actual "burns" are typically measured in FIRST, SECOND and THIRD DEGREE (the WORST of the three levels, this is when the NERVE has been burned through) based upon actual DAMAGE to the skin, all you will receive from snipping off a CANDLE—using the proper technique—is a mere MILD SINGE! ;)\n\nBest wishes.

The inner most part of t he burning candle is 800 degrees centigrades. The outer parts are somewhat less hot by a 100-200 degrees.

it's the same with a flame as well, I would assume that the heated gasses that burn off last are what causes it to be hotter.

You have 44 lbs of wax.  Melted wax with scent added will average about 18 fl. oz. per lb.  Based on that average you will have 792 oz. of melted wax. Divide that by the size of you candle to get your answer.  i.e. if you are pouring into 8 oz. molds you should get  approximately 99 candles depending on the type wax you are using.

A candle flame is often used to illustrate the complicated physio-chemical processes of combustion. The flame surface itself represents the location where fuel vapor and oxygen mix at high temperature and with the release of heat. Heat from the flame melts the wax at the base of the exposed wick. The liquid wax rises by capillary action up the wick, bringing it into closer proximity to the hot flame. This close proximity causes the liquid wax to vaporize. The wax vapors then migrate toward the flame surface, breaking down into smaller hydrocarbons enroute. Oxygen from the surrounding atmosphere also migrates toward the flame surface by diffusion and convection. The survival and location of the flame surface is determined by the balance of these processes. \n\nIn normal gravity, buoyancy-driven convection develops due to the hot, less dense combustion products. This action has several effects: (a) the hot reaction products are carried away due to their buoyancy, and fresh oxygen is carried toward the flame zone; (b) solid particles of soot form in the region between the flame and the wick and are convected upward, where they burn off, yielding the bright yellow tip of the flame; (c) to overcome the loss of heat due to buoyancy, the flame anchors itself close to the wick; (d) the combination of these effects causes the flame to be shaped like a teardrop.

If there is no oxygen present and it is in a vacuum then in fact it will melt at a certain degree. The wood wont burn without oxygen so you wont get ash, you get liquid wood.

Good question.  The flame converts wax into chemicals that evaporate into the air. Here's how it works:\n\nThe heat from the flame melts the wax into a liquid.  The liquid is drawn up the wick by a process known as capillary action.  The liquid wax is heated by the flame until it turns into a gas.  The gaseous wax combines with the oxygen in the air.  This chemical reaction produces many chemicals, but since wax is a hydrocarbon, (it contains mostly hydrogen and carbon, just like other flamable chemicals such as gasoline and wood) the byproducts are mostly water (a combination of hydrogen and oxygen) and carbon dioxide (a combination of carbon and oxygen).  In the heat of the flame, both water and carbon dioxide are gasses and float away into the air.  That is where the wax goes when the candle burns.

Take a piece of glass.\nBurn a candle.\nPlace the glass slightly above the flame.\nThe smoke of the candle will darken one side of the glass.\nMake sure that the glass is suffeciently darkned.\n\nNow look the sun.\n\nIt is perfectly safe. \nI have personally used it many times.

go see a doctor about it. i'm not sure what can be done about it. generally your tongue heals rather quickly. \n\nhow do you burn your tongue on a candle???

It has to do with the size of the wick more than it does color.  The wider the wick, the faster it pulls up molten wax to burn off.\n\nThe best way to test this is to take two candles that are identical except for color.  Buy the same brand, size, everything.  You'll see that they burn the same, or the darker candle may even burn slower (because of the color additives which make burning less efficient)

During spells DO NOT burn black candles you will be inviting entities from the evil side... There are some riuals that use black candles and they are for good but I have long forgot them - don't use them till' you know their purpose it is danger, death, dark, endings, blindness, confusion and deception.\n\nI no longer use black candles too many bad experiences....\n\nI have attended and red cards at big meetings many time and I "never" saw anyone burn black and red candles while reading cards, I don't burn any at all it doesn't make you weaker or stranger and it can be dangerous. Many places don't even allow them to be burnt for fire hazardous purposes.

Color is negligible or not at all a variable how long a candle burns, unless a certain pigment color has certain properties that makes it flammable.  The color of a wax candle should not affect ITS burn time.  Yellow candles burn just as quickly as red ones, sorry to say.

The "burn rate" of a candle depends on the type of wax (or other material being burned, e.g., "gel candles"), the type of wick, the geometry of the candle and wick, etc.  In general, though, burn rates for typical candles are on the order of 2-8 grams of paraffin/hour.\n\nParaffin wax is composed of straight-chain hydrocarbons with the general formula CnH2n+2, where n is greater than 20.  As the size of paraffin molecules increases, the carbon content approaches the limiting value of 85.7 percent asymptotically. For the sake of argument, let's say the wax in a candle is 85% carbon by weight (the rest is hydrogen).  This corresponds to a hydrocarbon chain containing about 20 carbons.\n\nIf the wax is burned completely, the overall chemical reaction involved is:\n\n  30.5*O2 + C20H42 -> 21*H2O + 20*CO2\n\nor, for each molecule of C20H42 burned, one needs 30.5 molecules of O2 gas.  For each atom of carbon in the wax that is burned, one needs 30.5/20 = about 1.5 atoms of oxygen gas.\n\nOxygen is the only gas in air that is consumed by the reaction, and if the candle burns prefectly cleanly, the only things produced are carbon dioxide (CO2) and water.  In reality, candles don't burn perfectly, and they produce some unburned hydrocarbons, soot, and carbon monoxide.  In addition, candles commonly have additives, such as colorants and fragrances, that are released.\n\nA candle that burns at a rate of 5 grams of paraffin per hour releases about 5*0.85 = 4.25 grams of garbon/hour (85% of the total mass).  The atomic weight of carbon is 12 grams/mole, so 4.25 grams/hour = 0.354 moles C/hour.  \n\nEach mole of carbon needs 1.5 times as many moles of O2 gas, so oxygen is consumed at a rate of 0.531 moles/hour.\n\nAt room temperature and pressure, a mole of gas occupies about 22.4 liters, so the candle uses up 11.9 liters of O2/hour.  As you point out, air is only 20% oxygen, so this is the oxygen contained in 11.9/.2 = 59.5 liters of air.  \n\n59.5 liters air/hour = (approximately) 1 liter air/minute.

Burning is something that happens to solids before they become a liquid and then a gas. The melting, boiling and evaporation points for water prevent it from being burned in any of it's states.

hot  wax  will  take  it  off  and   keep  it  off  longer. and  it  will  make  it   finer  and  not  as  thick,  the   longer you   use  it.
