OPAQUE WHITES (fire at 1450°F / 785°C for 2 minutes)

Low acid resistance:

1006 - a low expansion white used as the base coat for the crackle technique. Liquid form water base enamels are used for the second coat.

1010 - high softening point, high expansion. An ideal base coat for other enamels, especially transparents. It has good opacity, excellent gloss and surface.

High Acid resistance:

1020 - a super opaque titanium white with excellent covering power, gloss and surface. Used for Thompson's steel panels. Excellent one-coat or two-coat white for areas to be left white. Since expansion is on the low side, only thin coats of other colours should be applied over the white when used on copper.
