Cobalt carbonate has been used widely by potters for centuries. Salt glazed pottery produced in Germany has been found dating back to the 12th century. Add cobalt powders to glazes, slips and overglaze or underglaze washes and apply them to pots before placing them in the kiln. The result is a range of vivid blue hues. Very little powder is needed, as one part cobalt can color 100,000 parts of glaze.
To add a vivid blue color to enamel, glass and tile, use cobalt carbonate glazes and stains. Depending on the amount used, it creates a light or dark blue color. Use it to decorate porcelain, all types of ceramics, tile and glass works. Cobalt is also used in commercial stains, glazes and underglaze colors.
Use cobalt salts to supplement animal feed. Livestock such as cattle and sheep, which graze on natural food sources lack sufficient amounts of vitamin B12, which is necessary for proper development. Cobalt is an inorganic metal salt that, when added to livestock feed, provides vitamin B12. Grades of cobalt carbonate were developed for the animal nutrition industry to keep livestock healthy.
Cobalt is a transition metal that is used in various chemical processes. For the refining industry, it is used in the preparation of hydroprocessing catalysts. It is also used on a large industrial scale in the creation of chromium and steel alloys.
Proper care should be taken when working with any raw material, including cobalt carbonate. Protection should be worn at all times, and if symptoms of severe fatigue, shaking, gastrointestinal problems or muscular pain are experienced, consult your doctor.
