Manganese dioxide produces purple or brown in glazes. To substitute manganese carbonate, use one and one-half times more manganese carbonate than the amount of manganese dioxide in the recipe. Granular manganese dioxide is not suitable for glazes, as it will not disperse into a glaze melt because of its large particle size.
