Cobalt Oxide

Regular price $ 65.00

CoO is a metallic coloring oxide that produces blue in glazes at all temperatures (unless in very high percentages where it will be black). Cobalt is also useful as a body and slip stain. Cobalt materials are very expensive, this severely limits its practical use in many things. Larger amounts are available. Please call the store for quotes.
