Hydrocal® White Gypsum Cement (Plaster) offers twice the compressive strength of other plasters. Stiffening rate very rapid after setting action begins.
C$60.00
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
Kyanite is a grog with low thermal expansion and when added to clay bodies can reduce stress from dry shrinkage.
C$23.10
Gum CMC #7 Powder (Carboxy/Methyl Cellulose) is an organic cellulose gum which functions as a thickener, binder, and suspending agent in glazes.
C$35.75
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$22.00
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.
C$19.70
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
HG is a Soda Feldspar; Substitute for Minspar 200. It is composed of crystalline minerals made up of mainly of alkaline silicates. It is used in clay bodies to promote vitrification and in cone 6-10 glazes as an inexpensive glass-former.
C$6.50
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.
C$11.25
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
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
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
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.
C$13.55
