Pottery Plaster No. 1 produces break-resistant, smooth wearing molds for slip casting, jiggering, and press molds. The industry standard for making slip casting molds for ceramicware, sanitaryware, dinnerware, and fine china.
C$15.65
Feldspar Potash (Custer) is one of the primary feldspars used in ceramics. G200 EU is a 1:1 substitute for G200 in glaze recipes.

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.

The Reed Wax Emulsion is an excellent resist for the bottom of your pots and for brushing accurate wax resist decoration.
C$15.25
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$12.00
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
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
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
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.
C$10.40
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
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
Zinc Oxide (Calcined) is a useful, high temperature flux. It increases the maturing range of glazes and produces glossy colors (brightens copper and cobalt colours but may dull others). Higher amounts are used in zinc matte and zinc crystalline glazes.
C$13.20
Lithium Carbonate is used in ceramics as a source for Lithium in making glazes. A major flux for higher temperature (Cone 5-10) alkaline glazes, it tends to produce fluid glazes with glossy surfaces.
C$60.00
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
Potter's can use liquid latex as a resist for decoration as well as a mold building material.
C$8.00
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
Burnt Umber is the calcined (heated) version of raw umber, which is a natural brown to reddish-brown earth pigment. In ceramics, Burnt Umber is most commonly used as a body stain in light/white-colored clays.
C$13.90
Nepheline Syenite has been a used in the ceramic industry for many years, and is known for the whiteness it imparts to clay bodies and increasing low to mid cone glaze firing ranges.
C$10.40
Spodumene (substitute) is a silicate mineral often referred to as lithium feldspar. Commonly used in ceramics as a source of lithia which is used as a powerful flux especially when used with potash and soda feldspars.
C$94.15
Gillespie Borate is a blended borate material designed for use in glazes to replace Gerstley Borate. It has been on the market for over 20 years.
C$13.95
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
Titanium Dioxide is a glaze opacifier that is also a well-known white pigment. Titanate crystallization on cooling can lead to unique variegated surfaces.
