Over the years, Bullseye's Research & Education department has gathered a vast amount of experience slumping glass in a wide variety of molds. We've collected this information into a handy new reference guide and, in keeping with our mission of providing artists with the information they need to work successfully with our products, we offer it to you at no charge.

Note that these schedules are intended as a starting point. Developing an appropriate firing cycle involves many variables: Every kiln fires differently, different glass styles vary in viscosity, and so on.
