DEEP CLEAR GLASSY RESULTS
USING CASTING ROCKS!
Casting rocks are unannealed random shapes between the sizes of grapes and apricots. They are the lowest cost source of our premium formula casting glass. If your casting does not need the low bubble count and uniform shape of Casting Billets, choose Casting Rocks as an economical alternative. For blowers, they are also a great option as a replacement for Spectrum’s discontinued nuggets. Each container has a variety of piece sizes, so you can pick the size and weight you need to fit any mold. Click here to see our selections in System 96 and here for FX90. To purchase, contact your favorite supplier. You can find one here!
Questions about firing schedules? When planning a firing schedule for heavier castings, please refer to our Firing Guidelines. You will find that System 96 casting products can be fired at slightly lower temperatures than 90 COE ‘Bullseye Compatible’ or Artista fusible glass products, so you save on firing costs.
