How to Harden Paraffin Wax
Are your handmade candles burning down too fast, leaving pools of wax in their wake? When you mould with waxes, with melting temperatures of 60°C (140°F) or lower, you end up with too soft, badly burning, poor quality candles. How do you make your candles harder? By adding wax hardening agents, such as stearin, or clear or luster crystals, to the waxes.
These additives raise the melting point of wax, and improve candles significantly, in various ways: they harden the candles, making them burn longer; they maintain their shapes, (even in hot weather); have a better appearance, (with enhanced colour); slide out of their moulds more easily; and burn with less drips and trailing streams of smoke.
Stearin makes your candles more opaque. Clear crystals increase translucency.
