Choosing the right mold makes all the difference. There are many to choose from.
The first options may be purely on your budget. After that, of course it depends on the finished look you want.
Paraffin, Soy for pillars and palm wax will remove easily from any of the moulds.
If you are pouring palm wax, the mould needs to be able to withstand 90 to 100 degrees Celsius.
Beeswax tends to be a little 'stickier' and contract less than other waxes. It is generally better to use the cheaper 2 part moulds in the fantasy and economy ranges so that they can be easily removed from the wax. The small pyramid or pyramid 12 are also good from this range. Spending a bit more, the silicon is the best by far for a superior moulding.
