The general firing range for Thompson enamels is 1400°–1500°F (760°–815°C). Enamels will fuse in 1 to 4 minutes depending on the color, type and thickness of the metal, and the temperature of the kiln. A typical firing is 1450°F (790°C) for around 2 minutes. Enamel powders will change in color after firing. Refer to the color image for a general indication of the fired result. Computer monitors do not accurately represent color, and enamel colors may vary slightly from batch to batch, so pre-testing your enamels before using them is recommended. Bronze is not recommended for enameling. The enamels are not formulated to adhere to it and will crack or chip off.

Color Specific Information:

• Color: 1820 Goldenrod Yellow

Additional Firing Notes:
Cadmium colors will darken with prolonged firing. Edges are commonly black on copper and silver. Avoid over firing. This color does react with silver turning somewhat green at the edges, but the effect can be mitigated by fring over clear flux, either 2020 or 2040, and reducing kiln temperature to 1400°(760°C). A longer firing time will be needed. Watch enamel carefully to avoid over firing.
