Published in "Working Potter Glazes" in the June 2015 issue of Ceramics Monthly.

Old White is a matte off-white surface when applied in a single coat and is a glossy warm white in a double coat. It's a finicky glaze to apply, it will crawl if it is applied too thick or if multiple layers are applied too quickly. The glaze flashes any clay left raw next to a glazed surface area.
Mix all ingredients together prior to adding the water.
