Titanium Dioxide - Titania - TiO
Opacifier - develops crystals.
Similar in action to Silica.
Hardens the glaze making it more refractory with slight stiffening effect at low temperatures.
In amounts between 5-10% of a glaze opacity is pleasant with crystalline soft matt surfaces.
Has the power to transmute colour from the clay body beneath.
Lessens the solubility of lead in lead fritts.
Pure titania TiO
Rutile - natural titanium dioxide mineral with small amounts of iron (25%).
Intensifies colour in small amounts.
Moderate amounts (2-6%) breaks up the colour by mottling.
Large amounts tend to subdue colour giving interesting sparkles.
