Making A Candle With A Silicone Rubber Mold

This is my first try at making a candle by casting wax into a silicone rubber mold.


Candle wax shrinks a lot more than most other casting materials like resins or plasters. Along with a smaller finished casting you also get a significant loss of detail. Candles should be designed with this in mind to minimize the problem.

Thanks to Noura for sending in this project.

Here is a list of suppliers for the rubber, resins and waxes I use in my videos:
