Minspar 200 is a 200 mesh soda feldspar from Spruce Pine, NC. It is composed of crystalline minerals made up of mainly of alkaline silicates. Minspar 200 is used extensively in ceramics in both clay and glaze formulation.

Kyanite is a grog with low thermal expansion and when added to clay bodies can reduce stress from dry shrinkage.
C$22.00
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
Alumina Hydrate is a fine granular white powder that remains in suspension better in glaze slurries and has better adhesive qualities than Alumina Calcined. Used in glazes to increase hardness, aid stabilization and help resist crazing.
C$15.35
Alberta Slip duplicates the firing properties of Albany Slip and is an excellent base for many types of glazes.
C$11.70
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$26.40
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
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
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$10.80
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$15.95
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
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
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
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$16.55
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.
