Place on a heat proof surface.
Allow your new candle to burn for 2-3 hours when lighting for the first time as wax has a memory so the wax needs to melt all the way to the sides of the container.
Do not burn for more than 4 hours at a time to ensure that the wick does not build up too much soot, which could cause it to start smoking.
Make sure you stop burning your candle when 1cm of wax is left at the bottom of the container to avoid the base becoming dangerously hot.
Trim the wick back down to around 5mm before re-lighting.
Soy wax spills can be cleaned up with warm soapy water.
