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.

A high alumina/boron low calcium frit for Cone 06-01. Primarily used in art ware, hobby, and tile glazes. Alkaline, alumina borosilicate. Melting R...

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...

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

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

Grog is a hard-fired clay crushed to various mesh sizes. It may be added to clays for tactile and visual texture. It can aid in opening the body fo...

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...

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 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 type of feldspar which can be used in glazes. It is not desirable in clay bodies.

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...

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