How to Select for Your Surface or Project Type

For crystal-clear moulds and maximum repeatability, a translucent liquid like “Pure Mould” is preferable. Choose “I–Gum” for quick, small moulds when minimal preparation and easy handling matter most, such as for jewellery or miniatures. For complex models requiring the finest detail and several reproductions, the “Liquid Mould” line in various hardnesses delivers consistent results and long-lasting flexibility. Always check compatibility with your chosen casting medium—epoxy, wax, or plaster—and consider how much open time or curing speed best fits your workflow. The Silicone Rubbers category offers even more details for advanced needs.
