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.

Cornwall Stone is a low iron feldspar material used primarily as a flux in clay bodies and glazes. It is popular in engobes for its adhesive power during and after firing and in glazes for its low shrinkage and minimal contribution to defects.

Barnard Slip has historically been used by potters as a source of iron in dark firing glazes. Also referred to as Blackbird Slip, Banard Clay.
C$15.45
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.

Hydrocal® White Gypsum Cement (Plaster) offers twice the compressive strength of other plasters. Stiffening rate very rapid after setting action begins.

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.
C$14.50
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
Veegum, or VeeGum T (or VGT) is not a 'gum', rather it is a refined fine particle mineral called 'smectite'. In glazes VGT is used as an in-mix suspending agent and surface hardener. Also suitable for use as a spray-on surface hardener before decorating.

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.
C$9.90
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
Kyanite is a grog with low thermal expansion and when added to clay bodies can reduce stress from dry shrinkage.
C$20.00
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.
C$13.35
Silica (Flint) Sand 75 Mesh is often used in clay bodies instead of grog. It also can be useful to reduce body firing shrinkage. Silica sand can be used to diminish friction on kiln shelves to enable ware to move while shrinking to prevent sticking.
C$14.55
Hydro-Stone® Gypsum Cement is especially suitable where high strength and resistance to water absorption are necessary. It is ideal for applications in both the tooling & prototyping and art & statuary categories.
C$50.00
Kyanite is a grog with low thermal expansion and when added to clay bodies can reduce stress from dry shrinkage.
C$21.00
Granular Ilmenite is an iron titanium oxide mineral and can be used in small amounts to produce dark brown specks in clay bodies and certain specialized glazes.
C$8.45
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$32.15
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.
