Cobalt Carbonate (Pottery Colourant)
Colourants can be added to glazes to get the desired coloured effects. Unlike stains, colourants react differently in each firing. A wide spectrum of colours can be achieved by mixing them with other colourants, opacifiers & stains.
Name: Cobalt Carbonate (CoCO3)
Appearance Colour: Lavender
Form: Powder, Inorganic Compound
- In Slips: 0.25%-2%
- In Glazes: 0.25%-1%
Output Colour: Shades of vibrant blue. If mixed in the proper proportions with iron and manganese, intense blacks can be achieved. If mixed with magnesium and used as glaze, it can produce tones of red/purple in oxidation/reduction firings. On mixing it with white clay bodies for slips can result in various shades of blue.
