Aluminium
Aluminium moulds are an important tool for making candles of different shapes and sizes. Aluminium moulds are durable and easy to clean, but they are heavier and in rare cases may be prone to warping. Wick pins are also available for most moulds, which are not compulsory to use but allow a hole to be left in the middle of the candle at the time of casting, through which the wick can then be passed.
