Spectrum’s 1050 Underglaze Base is formulated as a base media for preparing your own underglaze colors similar to our 500 series underglazes.
C$13.00
The Reed Wax Emulsion is an excellent resist for the bottom of your pots and for brushing accurate wax resist decoration.

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
Frit 3134 consists of sodium, calcium and boron and is typically used in both transparent and opaque glazes. (also see Fusion Frit F-12 as a replacement - linked below.
C$8.15
On paper, Fusion F-12 has a very similar chemistry to 3134.

Copper Carbonate is a green powder used as a glaze or slip colourant. Depending on conditions and formulation it may produce green, blue-green or copper red (reds occurring most commonly in reduction firings).
C$29.70
Cobalt Carbonate is a fine particled lavender powder used as a colorant in glazes and slips. Very stable and reliable. Produces various shades of blue when used alone and will produce the same shades of blue when used in almost every type of glaze.
C$74.10
"NEW SUPPLIER! Please Test Under your own conditions." When applied on greenware or bisque as a method of decoration, "resists" application of glaze, slip and underglaze.
C$8.75
Potter's can use liquid latex as a resist for decoration as well as a mold building material.
C$8.00
This is a kaolin with intermediate particle size distribution. It contains low Fe2O3 and TiO2 content for applications where fired colour is critical. It has also proven useful in glaze applications.
C$24.55
Whiting is the most common source of calcium in glazes. It is a high temperature flux which gives durability and hardness to glazes. Whiting is the commonly-used name for Calcium Carbonate.
C$9.35
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
Titanium Dioxide is a glaze opacifier that is also a well-known white pigment. Titanate crystallization on cooling can lead to unique variegated surfaces.
C$26.60
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
Tin Oxide is the most effective opacifier to produce even, opaque, glossy glazes. Traditionally used as a white glaze stain, glazes opacified with tin may flash pink in kiln atmospheres where chromium is present.
C$31.40
Silica (Flint) 400 Mesh is a purified version of this much used material of glaze and claybody formulation. In clay and glazes, Flint provides the melting, or glassifying agents in a claybody that allow the material to fuse together.
C$14.25
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
Tile Clay #6 (6 Tile) is an airfloated kaolin with bright firing properties yet highly plastic. It thus offers high green strength for superior jiggering and wet processing properties.
C$22.00
Sodium silicate is commonly used in ceramics as a deflocculant in slip preparation by neutralizing the charges of particles in the slip, allowing for more even suspension and thinning.
C$9.00
Ultrox opacifiers assure uniformity of glaze opacity, texture and color over a wide range of temperatures and compositions.
C$11.90
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
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
Old Mine #4 Ball Clay (OM #4, OM4) is a fine-grained ball clay with excellent plasticity and strength. Old Mine #4 is an "industry standard" based on its popularity in both casting and plastic formed bodies. Also widely used as a suspension aid in glazes.
