Plastic candle moulds
Technical information about plastic moulds and dipping candles:
The crucial factors for a good result for dipping candles are the mixture of the wax as well as the temperature. For the use of plastic moulds you do best
when you take pure paraffin 56C. A supplement of 20% of stearin makes the candle more opaque. It will be upgraded optically as it does not shine through as much as normally.
Be careful with a higher concentration of stearin! When stearin is cooling it creates a high expansion pressure due to its crystalline character. This can
result in cracks in the moulds! Beeswax generally is gluey; please have some experiments to test the optimal pouring and removal temperature as well as the adequate size of the
wick. Generally one takes round wicks for beeswax and stearin.
The pouring temperature of paraffin is about 80 to 90 degrees. The use
of too cold wax results in a rustic surface (which might look well!). If you use too hot wax it will pass through all the gaps and might destroy the moulds (generally moulds
can’t cope with more than 130 degrees).
