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.

Gerstley Borate is a sodium-calcium-borate compound used in ceramics as a low and mid-range temperature flux. It is essentially a source of boron in glazes, and acts as a melting agent. It also can act somewhat as an opacifier and prevent crazing.
C$27.00
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
Alberta Slip duplicates the firing properties of Albany Slip and is an excellent base for many types of glazes.
C$9.75
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
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
Wollastonite is a natural calcium silicate used to reduce shrinkage in clay bodies and glazes during firing. Can aid in the fast firing of clay bodies and can be employed to replace silica and whiting.
C$10.35
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
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$22.00
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 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
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
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$23.10
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
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$39.20
Boric Acid is a water-soluble boron mineral. Boric Acid is used as a B2O3 source in the formulation of frits and glazes.
