Mold Making And Casting: 73-25 Silicone Irregular Block Mold

This is a moldmaking technique that may be used to reduce the amount of silicone used for a mold. By conforming the mold to just 1/2“ outside the pattern the overall cost of the silicone mold is reduced. We used our 73-25 silicone for this mold as it is a very low viscosity silicone.
