Mulcoa Kaolin Grog 35 Mesh is a medium-grained calcined mullite grog. This grog can be added to throwing and sculpture clay bodies to increase working strength and reduce shrinkage as well as an aid in drying thick pieces.
C$22.00
Mulcoa Kaolin Grog 20 Mesh is a coarse-grained calcined mullite grog. This grog can be added to throwing and sculpture clay bodies to increase working strength and reduce shrinkage as well as an aid in drying thick pieces.

Silica (Flint) 400 Mesh is a purified version of this much used material of glaze and claybody formulation. In clay and glazes, Flint provides the melting, or glassifying agents in a claybody that allow the material to fuse together.

Alberta Slip duplicates the firing properties of Albany Slip and is an excellent base for many types of glazes.

Feldspar Potash (Custer) is one of the primary feldspars used in ceramics. Mahavir has been found to be a good substitute for Custer, however, as with any raw material change in a recipe, please test first.
C$8.40
Petalite, a lithium feldspar with a high silica content, is used both in glazes and clay bodies to help decrease thermal shock.
C$15.75
Kyanite is a grog with low thermal expansion and when added to clay bodies can reduce stress from dry shrinkage.

Iron Chromate is used in glazes to produce gray (with feldspar), brown (with zinc), red (with tin) or black depending on the base glaze and percentage and other colouring oxides present. Often used in underglazes, engobes and clay bodies.

Cryolite is a powdered material derived from granite. It is a strong fluxing agent with a very low melting point. Cryolite is used in frits and glazes, and is a source of aluminum and insoluble sodium.
C$39.20
Borax Decahydrate is 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 glazes.
C$13.55
Silicon Carbide is a reduction agent used in glazes. It can be used to make crater glazes. Silicon Carbide can also can be added to clay bodies to give black speckling.

In ceramics, Manganese Granular is used primarily in clays and glazes to achieve fired speckle (including the brick industry). This is the same material as manganese dioxide powder, it is simply not ground to a fine powder.

Magnesium Sulphate, also known as Epsom Salts, is a flocculant and can be used to thicken a glaze to improve adhesion to non-porous surfaces. Also acts as a suspension agent in slip or glazes. Adding too much can have an adverse effect.
C$8.35
Macaloid is geologically and chemically similar to Bentonite. Used as a suspension agent in glazes, Macaloid can increase the drying rate of water suspended glazes.
C$18.75
Boric Acid is a water-soluble boron mineral. Boric Acid is used as a B2O3 source in the formulation of frits and glazes.
C$4.55
Alumina Calcined is an intermediate oxide used to stabilize fluxes and glass formers that compose glazes affecting mattness and brilliance. Adds strength and prevents devitrification.
