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.

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.

Veegum, or VeeGum T (or VGT) is not a 'gum', rather it is a refined fine particle mineral called 'smectite'. In glazes VGT is used as an in-mix suspending agent and surface hardener. Also suitable for use as a spray-on surface hardener before decorating.

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.
C$7.80
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
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
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
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 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
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
Fabi Talc is both white in it’s raw state, and in it’s fired colour. Talc is an hydrated magnesium silicate, its crystals are thin and lamellar forming. Talc can be found in various grades, different by purity, colour and lamellarity.
C$17.15
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
Kyanite is a grog with low thermal expansion and when added to clay bodies can reduce stress from dry shrinkage.
C$22.00
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
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
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
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.
