Elan Gray 2910 TRANSPARENT ENAMEL
2 OUNCE JAR ~ 8 ounce also available ~
If you look at the legend for transparent colors fired over different bases or substrates (the white square with the four blocks marked “White,” “Flux,” “Silver,” and “”Copper,”) and compare them to the color sample blocks, you can get an idea of what the transparent color looks like over different bases. For instance, the lower right block is the color fired over bare copper. Because the color is directly exposed to the copper oxides, it is always the darkest of the four samples. The upper left shows the transparent over white. This usually shows the color in its brightest most colorful form. “Flux” means clear and the upper right block shows the color fired over a base coat of clear flux enamel such as 2010, 2015, or 2030. “Silver” means it is fired directly over sterling silver metal.
