Plaster Investment Recipe for Bronze
 

These recipes have been used extensively on bronze and has produced some high quality castings. The method is to mix the ingredients in the order as listed adding the water last, the mixture appears dry as you mix, but will result in a creamy consistency that cures to a good strong plaster composite.



Degrease the wax pattern with a thin shellac sealer.

 

Detail Coats 

Detail coat with a creamy consistency and applied with a brush over the wax pattern, leave to fully cure before adding support coat. Cover the pattern thoroughly with a 1mm or 2 mm coating, apply a second or third coat depending on size and shape of pattern.
