All of the Thompson Enamels that we carry are medium temperature, medium
expansion enamels for gold, silver, copper, and low carbon steel.
Normal firing temperature range: 1400-1500˚F
Coefficient of expansion: 258-360 cubic expansion
Since color photography cannot accurately
reproduce the true richness and brilliance of these colors,
and since all computers, monitors and browsers display
colors differently, we suggest a pallet of fired samples be made.
