Reach target color when firing our 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. This applies to all forms of these glasses: sheet, billet, rod, frit, etc.
However, we’ve discovered something interesting in the process of testing our 1800 series of gold-bearing tint styles. It’s possible to produce a variety of hues by firing these styles with a shorter pre-rapid heat soak hold of 30 minutes. Testing is required, since the color development varies in different production runs, and within a single production run.
Note that firing these styles with the 30-minute pre-rapid heat soak permanently affects color development. You may be able to continue developing color by firing again with a longer soak, but this will not push the glass to its target color.
