Why cast in Sugru?
This guide will show you how to make a cheap and simple mould out of a silicone compound called Sugru. From this heat-resistant mould one can create a Pewter casting, for jewellery and such. Although a professional casting will deliver a more robust and larger mould, it is fair to say for small, detailed 1-offs, I found using Sugru to be a simple and cost-effective method. Indeed, the moulds I’ve made here have been re-used 3-4 times with pretty good results. (The moulds can also make wax candles too, for a geeky AFOL Birthday Party!)
