easy to make gel candles. Due to colour combinations and different mould forms you can freely express you creativity. Principally you only have to liquefy gel wax and fill it into suitable moulds. The perfect diameter is about 6 cm, the optimal height is likewise about 6 cm. The use of moulds that are too small might end in a soot production as there is not enough oxygen supply for the flame. In moulds which are too big the flame will drown. A bigger wick might be to counteract. On the other hand, wicks that are too big produce soot, as well.
The easiest is to take a poke wick (flat wick 3x9 is a great standard wick). It has just to be poked in almost solidified
Wicks with a metal stand burn for a longer time since they don’t overturn ahead of time. You have
to fix them on the bottom of the glass, and use e.g. a wick needle to keep them vertical while pouring the wax..
