Best-To-Test
To consistently reach target color when firing select gold-bearing striking glasses, Bullseye advises a pre-rapid heat soak of 2 hours at 1225°F / 663°C on the way up to process temperature during the first firing. We call this the ‘Gold Hold.’ It applies to all forms (sheet, billet, frit, etc.) of the certain gold-bearing glasses.
The production of gold-bearing glass styles involves numerous variables, making each melt unique. We’ve observed that these styles can be particularly sensitive during firing. To ensure consistent color development, we’ve developed a best to test list. It highlights colors that may not fully develop in kilns that run hotter than average.
