Dolomite is a type of milled limestone that is a useful source of both calcium and magnesium in ceramic glazes.
C$10.90
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
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
Bone Ash (TriCalcium Phosphate) is source of calcium and phosphate traditionally used in bone china for translucency and lowering the maturing temperature.
C$13.55
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
Feldspar Potash (Custer) is one of the primary feldspars used in ceramics. Mahavir has been found to be a good substitute for Custer, however, as with any raw material change in a recipe, please test first.
C$8.40
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
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
Bentonite is a fine powder that is a grey-tan color. As typical for ceramic use, this is a sodium bentonite and is a common additive to both glaze and clay. Use in small percentages to aid clay body plasticity and glaze suspension.
C$9.85
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
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
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
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.
