Bullseye billets can be an excellent choice for casters who are concerned about the safety issues in working with lead crystal. Bullseye billets are also significantly lighter than lead crystal and may be
more economical to use. In comparing costs, remember that full lead
crystal glasses weigh as much as 45% more. The specific gravity of
Bullseye glass is about 2.5.
Billet size: 5" x 10" x ¾"
Estimated Billet weight: 3.5 lbs.
