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.

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.

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.

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.

Gillespie Borate is a blended borate material designed for use in glazes to replace Gerstley Borate. It has been on the market for over 20 years.

Hydrocal® White Gypsum Cement (Plaster) offers twice the compressive strength of other plasters. Stiffening rate very rapid after setting action begins.
C$60.00
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$9.40
Silica (Flint) 200 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.
C$11.30
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$15.95
Alberta Slip duplicates the firing properties of Albany Slip and is an excellent base for many types of glazes.

Ravenscrag Slip is a silty low iron clay, it applies evenly, drains drip-free, dries hard, does not settle. Mixed with water alone, makes a nice semi-matte cone 10 clear glaze.

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$11.20
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
Kyanite is a grog with low thermal expansion and when added to clay bodies can reduce stress from dry shrinkage.
C$22.00
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
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
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.
