ALUMINA CALCINED 100#
10 150 A$10.00 - A$150.00
Alumina 100# may be used as a source of alumina in glazes where it will have the effect of raising the firing temperature and increasing viscosity. Overloading with alumina has a matting effect. The tendency of glazes with high clay content to crawl may be reduced by the introduction of alumina as part replacement for clay. Alumina is also a useful addition to underglaze colours if the underglaze crawls.
