How do I use Bullseye slumping molds?
You can start by reading Tips for Using Bullseye Slumping Molds. Since different molds require different firing schedules, you'll have to experiment, ask questions, and gain hands-on experience to become an expert in planning the heatwork.
Note: The measurements stated for molds in the Bullseye Catalog and in our Online Store are of the outer dimensions of the mold. This is to help you determine whether a given mold will fit in your kiln. Molds are handmade, so slight variations in size are to be expected. Individual molds will vary—never cut glass to fit until you have measured your mold.
