Raw Materials

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

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

Opaque glaze in the Laguna Cone 5 Dry Glaze Series. An opaque, white gloss glaze which contains tin to give it a bright clean white color. Medium a...

H3BO3 or B2O3.3H2O  Boric acid is a water-soluble boron mineral. Boric Acid is used as a B2O3 source in the formulation of frits and glazes. Ty...

Most often used as a specking agent in clays.

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

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

Produces grey brown colors in engobes and in underglazes that include zinc. If tin is present it may produce pink and reddish browns. Can also be a...

Alumina Oxide is an intermediate oxide, and is used to stabilize fluxes and glass formers that compose glazes. It is calcined and ground to 325 mes...

A refractory material used to reduce shrinkage in clay bodies. Because of its interlocking crystal structure it also gives strength to clay bodies. 

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

A water soluble, low temperature flux which lowers the fusion point of glazes and promotes a smooth melt. A source of sodium and boric oxide in gla...

This is a blend of minerals that closely simulates Barnard (Blackbird) Clay, a widely used clay that contains iron and manganese.

Alumina Oxide is an intermediate oxide, and is used to stabilize fluxes and glass formers that compose glazes. It is calcined and ground to 325 mesh.

A fine grained secondary clay which fires to a light cream with 13% shrinkage at cone 10. This ball clay is considered to be very effective in salt...

A hydrated ferric oxide with manganese dioxide. It is used for brush decoration to produce a reddish-brown. Also can be added to clay bodies to ach...

A coarse-grained fast-casting ball clay with medium plasticity and strength. SGP is an "industry standard" based on its popularity for casting. Can...

Superpax supplies ZrO2 and SiO2.A fritted zirconium opacifier; very fine grain.

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

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...
