What is Titanium Dioxide? The Put and Take Testing Method of Titanium Dioxide Glaze. How to get Cool Crystal Effects with Titanium Dioxide Ceramic Glaze?
Titanium Dioxide (TiO2) also known as titanium(IV) oxide or titania. When used as a pigment, it is called titanium white, Pigment White 6 (PW6). Titanium dioxide is the most widely used white pigment because of its brightness and very high refractive index. TiO2 is also an effective opacifier in powder form, where it is employed as a pigment to provide whiteness and opacity to products. In paint, it is often referred to offhandedly as "brilliant white", "the perfect white", "the whitest white", or other similar terms. Opacity is improved by optimal sizing of the titanium dioxide particles.
All pigments for ceramics are intermixable so why not get creative and experiment by missing your own completely fresh color. During the firing process, the colors fuse extra vigorously creating purity, intensity, and brilliance. The colors are stronger, therefore, significantly less percentage is needed to create vivid colors making them excessively cost-effective.
How to use Titanium Dioxide in the pottery:
Titanium is the strongest white pigment known for many uses, in ceramics the whiteness (and opacity) it imparts to glazes is due to its tendency to crystallize during cooling. Titanium dioxide is used in glazes as an opacifier. It can be used as an additive to enliven (variegate, crystallize) the color and texture of glazes by introducing crystallization. Rutile works in a similar manner, typically both become saturated in the melt beyond about 5-6%, producing a dry and unstable glaze surface. In moderate amounts, it encourages strong melts, durable surfaces, and rich visual textures.
When using ceramic pigments in glazes, usually in concentrations of 1–10%, a little more care must be taken because some pigment systems react with materials in a glaze.
