SE-2 Separation Enamel: Available in Dry Powder or Oil Base. Separation Enamel is painted in a linear design over 2-3 coates of pre-fired transparent and/or opaque enamels, with transparents being the final coat. When fired, the separation enamel changes the viscosity of the area producing a flowing or spreading somewhat similar to a marbleized effect. Dry and fire at 1450 - 1550°F for 2-5 minutes.
