Alumina Oxide, Calcined Size:1 kg stir well and apply 2

stir well and apply 2 coats to bisqueware

25% added 60-80 mesh granular manganese and an additional 4% fine grog

Thin with water or media to create a “wash” or watercolor style of design

More plastic than porcelains but semi-vitreous to promote stability in the kiln

Titanium dioxide’s the whiteness and opacity is due to its tendency to crystallize during cooling

Alumina Oxide, Calcined Size:1 kg stir well and apply 2Alumina oxide is a chemical compound of aluminium and oxygen, and is commonly called alumina. Essentially a refractory, it is responsible for the matteness or brilliance of glazes. However, too much alumina can cause a dry appearance. It prevents devitrification and adds strength. Alumina oxide is insoluble in water and has a high melting temperature of 3550 F. Because of this, alumina oxide can lend great strength to clays and glazes and is
