Enamels

     Thompson Enamel carries a full line of opaque and transparent enamels for use on copper, silver, gold, stainless and low carbon steel, as well as enamels for window, stained, Effetre (Moretti) glass and hot glass blowing.  Our full line offers enamels in powder form (80 mesh standard - can be ground to different mesh sizes, eg. 325 mesh), 6/20 mesh for beadmaking, or unground, unsifted enamel (opaques - air cooled; transparents - air cooled, water cracked; size varies from approx. 1/8" to 2"), in a wide variety of hues and colors.

     All enamel products in our catalog are numbered into a practical coded numbering system which indicates enamel type and color.  This coding can be easily seen by examining our color charts here.  The thousands number indicated enamel type while the hundreds number indicates the color.  The final two numbers indicate how light or dark that color is.  For example, 1505 is an opaque pastel greenish blue for copper, and 2680 is a transparent dark blue for copper.

IMPORTANT:  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.
