Magnesium Carbonate Pottery Cascade Glazes but when combined with theSource of magnesium oxide in glazes. Imparts strength and colour and in large amounts it imparts an opaque dry quality to glazes. Magnesium carbonate can crawl glazes because it decreases melt mobility. The exceedingly small particle size of the material increases shrinkage.
