CR-12 is a glossy white glaze with black specks that, when fired, crawls into raised shapes of varying sizes and forms. The result is a surface marked by unpredictable, natural patterns that add unique texture and visual interest to each piece. The featured chip image of CR-12 is applied on AMACO No.30 Milk Chocolate Clay. Layering Sample Images are 2 coats over 2 coats, fired to Cone 6. Apply 1-4 even coats of glaze to cone 04 bisque. Allow each coat to dry almost fully, but before any significant cracking occurs. Crawl glazes will develop hairline cracks as they dry; handle with care. For added durability before firing, layer over an AMACO Celadon glaze or underglaze. More coats create larger glaze dots, while thinner coats produce a finer bead effect. Increased coats will produce more cracks. Fire to cone 5-6 for best results. These glazes are food safe when layered over AMACO Celadons.
