  • well the ones I get the middle melts down and we save the wax. . . but others can evaporate and burn off. . . I think it has something to do with the type of wax used to make the candle.

  • It evaporates into the air? Will there eventually be a build up on your walls if you burn a lot of candles?

  • The wax will evaporate and yes, you can get a waxy buildup if you burn lots of candles in small spaces, but it has to be A LOT and a pretty small area. In most homes you will never notice it.

  • Waxes are hydrocarbons - this means the wax itself is made of carbon and hydrogen molecules. When you heat it, the hydrogen and carbon molecules are released as a gas - this gas just mixes in with the air (which is why others said evaporation).

    If you have scented candles, the scents are often made using benzene-like molecules, which are also made mostly of hydrogen and carbon, which will mix with the air when made into the gaseous form.

    Usually burning candles won't cause a build up on the walls because the hydrogen and carbon is released into the air as small molecules, not as chunks of hot wax.
