GLASS SPECIFICATIONS

Bullseye produces glasses with a number of different base compositions. For this reason, all glasses will not have the same softening, or annealing points. Briefly, the three primary categories of Bullseye glasses are: transparents, opalescents, and lead-bearing gold pink transparents.

The relevant temperature data for these glasses are*:
  Transparents Opals Gold Pink Transparents
Strain point: 920F (493C) 865F (463C) 820F (438C)
Annealing point: 990F (532C) 935F (501C) 882F (472C)
Softening point: 1250F (677C) 1270F (688C) 1180F (638C)
*As determined by the standard test method for annealing point and strain point of glass by fiber elongation, ASTM Designation C336-71, performed at Corning Engineering Laboratories.
