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.
