  • A stronger, economical mold material
  • Provides added strength for the glass artist that struggles with mold integrity due to mold size or process intensity

Mold Making
Mix 100 parts Glass-Cast powder to the appropriate parts water by weight. Mix for 2-3 minutes. R&R recommends mechanical
mixing to achieve the best mixing action. It is possible (but not required) to vacuum the mix until the investment rises and
breaks to eliminate entrapped air before pouring around the pattern.
Pour the Glass-Cast mold material down the side of the flask or mold frame until the patterns are covered to an appropriate
depth. This depth will vary depending on the size of glass casting and the strength of the mold material you use. It is possible
(but not required) to vibrate or vacuum the mold to remove air bubbles, which may adhere to the patterns. This operation
normally takes 1-1½ minutes. R&R recommends that the mold then sit a minimum of 1 hour after it has set, before moving
onto pattern removal.
