A naturally mined iron titanium oxide mineral. It is generally black as sand, odorless, tasteless, opaque under a microscope, non-flammable and ins...

Source of magnesium in glazes. Imparts strength and color with little shrinkage. In larger proportions, it produces a dry opaque quality to glazes.

Good substitute for Custer Feldspar. A selected white firing high grade potassium feldspar ground to 200 mesh for ceramic applications. Moderate po...

A weak coloring agent. In an alkaline glaze, a blue-purple or plum color can be obtained. In leadless glazes, a purple-brown may result. It is a po...

A black powder which gives red, brown, purple or black tones to clay bodies and glazes. A strong flux when added in large amounts to clay bodies.

A soda spar. It can reduce crazing tendencies when added to a clay body. Also used in glazes where a soda spar is required.

Common glaze colorant. Green nickel produces a variety of browns, blues, grays and yellows depending on the presence of other materials in the glaze.

A natural hydrated earthy ferric oxide. Contains hydrated iron oxide. Can be calcined at 550-600°C.

Also known as Pearl Ash. It is a strong flux and can be used as a color modifier in glazes.

Can be used to increase plasticity in porcelain bodies instead of Potash Feldspar; a complex material similar to and sharing properties with Potash...

Ferric oxide. Basically the same as black iron oxide except not as concentrated.

A titanium dioxide tan colorant which contains a small amount of iron. Used both for color and its tendency to provide various mottled textures.

This is classified as a Dark Rutile. This is the same mineral as the ceramic grade rutile but this has not been calcined.

Opaque glaze in the Laguna Cone 5 Dry Glaze Series.

325 mesh silica is typically used in glazes.

AKA Flint. The most common source of silica in clay bodies and glazes. Increases the thermal expansion in clays and decreases thermal expansion in ...

Feldspathic silica sands which can be used in place of grog in clay bodies to add texture and strength.

This is an active flux which serves an important function as a deflocculant in preparing liquid slip. It increases strength and workability and red...

Crystalline minerals made up of mainly silica and alumina in combination with sodium and potassium oxides. Often considered a natural frit. Used ex...

Sodium silicate is commonly used in ceramics as a deflocculant in slip preparation by neutralizing the charges of particles in the slip, allowing f...

81% Fe2O3 , this imported, natural iron oxide is bright red in its raw form.

Substitute for Spodumene. A source of lithia, which is a flux, that helps to develop copper blue tone glazes. Can replace feldspar and also reduces...
