Frequently Asked Questions

Is the Silli mould kit food safe?

Yes. Once cured, the silicone produced by the Silli kit is food-safe and suitable for use with fondant, chocolate, gum paste, and other edible mediums. Always ensure the object you are moulding is clean and, ideally, non-porous before taking a mould from it.

How many moulds can I make from one Silli kit?

The number of moulds per kit depends on the size of the object being moulded. Smaller objects allow multiple moulds from one kit. A kit will typically yield between 2 and 4 medium-sized moulds. Plan your objects in advance to make the most of the compound before it sets.
