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

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
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
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$11.10
Gum CMC #7 Powder (Carboxy/Methyl Cellulose) is an organic cellulose gum which functions as a thickener, binder, and suspending agent in glazes.
C$29.75
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
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.
C$6.80
Hydrocal® White Gypsum Cement (Plaster) offers twice the compressive strength of other plasters. Stiffening rate very rapid after setting action begins.
C$60.00
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$19.50
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
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
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$9.70
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$12.00
Kyanite is a grog with low thermal expansion and when added to clay bodies can reduce stress from dry shrinkage.
C$20.00
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.
C$19.50
Boric Acid is a water-soluble boron mineral. Boric Acid is used as a B2O3 source in the formulation of frits and glazes.
