Ilmenite (Milled) - Various Sizes

Ilmenite supplies titanium and iron oxides to glazes. Increasing amounts cause glaze opacity and, eventually, matte surfaces. Titanate crystallization on cooling can lead to interesting, variegated surfaces. The iron in ilmenite is a colorant, typically muting other colouring oxides. Purer sources of TiO2 for glazes are rutile (96%) and white titanium dioxide (99%).
