Cone 6: Root Beer provides translucent, rich, brown gloss color. Designed to provide a hint of color with one coat, deeper color with two to three coats - but remaining translucent. Cone 10: Color darkens. TIP: One coat allows more of the clay body characteristics to appear through the glaze, adding a faint color gloss to the surface. Subsequent coats deepen the brown color but at three coats you will still obtain a translucent fired surface. Three coats will produce more opacity and less translucency. This glaze may have some mobility with thicker applications.
