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.

Additional Firing Notes:
This color fires well on copper, but reacts with silver turning it green. This example was fired on sheet silver. Color reactions may be magnifed on silver clay due to the porosity of the metal. The test piece was fired both directly on silver and over a single coat of 2040 Hard Fusing Clear. Two coats of clear, either 2020 or 2040, and multiple coats of the color may improve the results.
