Soda Ash (Sodium Carbonate), a fine granular material, is an active flux and also serves an important function as a deflocculant used to thin slips and slurries. It increases strength and workability and reduces shrinkage.

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
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$21.00
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
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
Hydrocal® White Gypsum Cement (Plaster) offers twice the compressive strength of other plasters. Stiffening rate very rapid after setting action begins.
C$60.00
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
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$8.95
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.
C$21.00
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
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.
C$24.00
Kyanite is a grog with low thermal expansion and when added to clay bodies can reduce stress from dry shrinkage.
C$23.10
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.
