Manganese Carbonate Ceramic Glazes

Manganese is usually introduced into glazes as manganese carbonate.

Manganese carbonate ceramic glazes.

Manganese carbonate is a relatively powerful ceramic flux. Handle with caution using all safety precautions. It is also used in health foods in ceramics as a glaze colorant and flux and in concrete stains. As these elements begin to melt they form the glassy surface which acts as the basis of the glaze.

Quantity discounts are available. Manganese carbonate is widely used as an additive to plant fertilizers to cure manganese deficient crops. Fluxes are used to lower the high melting point of the other glass elements such as silica or alumina. In leaded glazes manganese carbonate can produce purple tinged with brown.

Manganese is a weak coloring agent in glaze formulas. Manganese dioxide powder left and manganese carbonate right cone 10r dolomite matte glaze with 5 manganese dioxide. An original container of manganese dioxide. In high alkaline glazes.

In an alkaline glaze manganese carbonate can produce blue purple and plum colors. It is used in medicine as a hematinic. Black manganese dioxide is more often used in slips and clay bodies where its coarseness yields spots and splotches.
