Thompson Enamel Opaque - Medium Temperature, Medium Expansion enamels are a glass product formulated to create a permanent bond with fine silver, copper, and gold. Bronze is not recommended for enameling. These high quality, acid-resistant, 80-mesh enamels will provide rich, beautiful color for your metal clay work.

*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.  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:
Color Code: (C) Contains Cadmium - (C) Grade colors often react with silver. Fire over a flux coat of 2020 clear or 2040 clear when firing on silver clay. Fire this color at a lower temperture to avoid over firing.
