 Through years of formulation and reformulation, Karl Miller developed Albany Slip Substitute intended to reproduce the physical and performance characteristics of the famed Albany (NY) Slip.
|
An excellent substitute for the very popular Albany Slip, which has not been mined for over a decade. It melts fairly well from cone 6 up. By cone 10 it produces a glossy brown in oxidation and a tenmoku in reduction.
|
Hydrated alumina is a fine granular white powder that is typically added to glazes as a source of alumina.
|
Alumina Oxide is an intermediate oxide, and is used to stabilize fluxes and glass formers that compose glazes. It is calcined and ground to 325 mesh.
|
Derived principally from stibnite, its principle use is an opacifier in porcelain enamels.
|
A very plastic ball clay used in industrial and hobby clay bodies of all types. Primary applications are dinnerware and artware. Not stocked in CA.
|
C&C is a fine-grained engineered blend, well known for its excellent plasticity and fired properties. An extremely consistent blend suitable for a wide variety of forming processes, where a high degree of plasticity is required.
|
FHC is an intermediate-grained engineered blend offering excellent moisture retention and plasticity properties. Ideally suited for a wide variety of stoneware applications and wet forming process.
|
A coarse-grained, siliceous, illitic Ball Clay known for its high strength and plasticity. Applications include artware and ceramic tile.
|
No. 5 clay is a kaolinitic ball clay containing low levels of carbon. It provides high suspension and plasticity to a variety of ceramic formulations and is an excellent source of Al 2O 3 content.
|
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. It is also widely used as a suspension aid in glazes.
|
A coarse-grained fast-casting ball clay with medium plasticity and strength. SGP is an "industry standard" based on its popularity for casting. Can also be used in plastic formed bodies and is widely used as a suspension aid in glazes
|
A fine grained secondary clay which fires to a light cream with 13% shrinkage at cone 10. This ball clay is considered to be very effective in salt firing and it is claimed that it works well in flashing (i.e. wood firing).
|
This is the main source of barium oxide in glazes where it functions as a flux and assists in producing matte finishes. It is also used to neutralize sulfates in clay bodies.
|
This is a blend of minerals that closely simulates Barnard (Blackbird) Clay, a widely used clay that contains iron and manganese.
|
The most commonly used bentonite, and is considered a standard glaze and clay additive. It can at times be coarser than 325 mesh, and may cause some specking if used in amounts over 1%. A Sodium Bentonite.
|
A non-swelling Calcium bentonite and our lightest colored Bentonite. Excellent for use in clay bodies, especially in conjunction with Macaloid in porcelains.
|
(Air Purified) Ultra-fine ground, air-purified Bentonite recommended when a finer grade than 325 is needed for glaze applications.
|
A suspension agent that increases the drying rate of water suspended glazes. It is similar to a very clean, white type of Bentonite. Also used as a plasticizer in fine porcelain.
|
A macaloid-type Bentonite suspension agent for glazes. Also used as a surface hardener. An extremely plastic, hydrous magnesium silicate used to give plasticity to non-plastic whiteware and refractory bodies. Very similar to Macaloid.

|
An important source of calcium phosphate made from calcined cattle bones. Real bone ash is chemically inert and free of organic matters. Calcium acts as a flux, and phosphorous as a glass former.
|
A water soluble, low temperature flux, which lowers the fusion point of glazes and promotes a smooth melt. A source of sodium and boron in glazes.
|
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.
|
Boric acid is a water-soluble boron mineral. Boric Acid is used as a B 2O 3 source in the formulation of frits and glazes.
|
Added to powdered glazes it produces a brushing consistency for smoother and a more even application.

|
This is the most common source of calcium in glazes. It is a high temperature flux that gives durability and hardness to glazes. 98.0% CaCO 3 with 1% retained on a 325 mesh sieve.
|
A versatile colorant used in glazes to most commonly produce various green tints.
