Cobalt Carbonate

Cobalt Carbonate (CoCO₃) is a deep blue powder used in ceramics to produce vibrant blue colors in glazes, stains, and decorative slips. It is highly stable during firing, providing consistent color in both oxidation and reduction atmospheres, making it essential for blue-and-white wares and high-temperature glazes.

Cobalt is expensive because it is a rare metal, mined in limited quantities, often as a byproduct of nickel or copper production. Its extraction requires complex processing, and global supply is concentrated in a few regions, which drives up the cost of cobalt-containing materials like Cobalt Carbonate.

Cobalt Carbonate is toxic if inhaled or ingested and can cause skin or respiratory irritation. Always wear gloves, a dust mask or respirator, and work in a well-ventilated area. Do not use it on functional ware that will contact food or drink unless fully encapsulated in a stable glaze.
