Hi all! :)


I would like to experiment with making my own molds for sugar paste relief work.


 I have searched the internet for alternatives for food grade silicone and could only get

one thread where someone suggested using marine aquarium silicone since it is food safe (I would

have to double check this before I consider baking a cake commercially!). 


I have also read on this forum that people suggested using Gum paste instead of the silicone. But I understand that the mold might not be able to be used multiple times?


I want to know if other members have tried their own versions of "silicone molding" with alternative mediums and what was your experience?


(If there is anyone who can point me in the right direction in South Africa (Gauteng) as to where I can at least find food safe silicone putty I would be grateful!  The international shipping seems quite steep...)

I don't know if it is available in South Africa, but try to find Amazing Mold Putty. It is easy to use and is food safe.

This is what I use to make molds. You can buy it from the website if you can't get it in a store where you are.

Mrs Glowworm, did you manage to get something??
Im also based in Gauteng and im also looking for it.


I googled dental Putty, but setting time is 1 to 1.5 minutes, which is not long.

You can use gelatin to make molds if your casting with gum paste.


Hollywood has been using gelatin for quick molds and prototyping as well as casting pieces for special effects makeup for decades.


The trick is to use very high bloom gelatin and as little water as possible.


Special effects link:



(Water content is what causes gelatin and alginate molds to shrink as they dry.) (PS - Alginate is fragile and has a high moisture content so may not work for master molds.)
