CH411
Calcium Carbonate 325-mesh
WHITING: the main source of calcium oxide in glazes. High temperature flux giving durability and hardness to glazes.

CH311
Chrome Oxide
A versatile coloring oxide used in glazes to produce various green tints. Produces blue-green hue when combined with cobalt oxide, or browns with zinc oxide.

CH400
Clay C Red
A smooth, plastic fireclay with very high iron. This material's fine nature and high iron content make it suitable for terra sigillata.

CH377
Clay Gold Art
A very plastic air-floated secondary clay used in clay bodies where recipes call for ball clay or fireclay. Fires to light cream with approximate 7% shrinkage at cone 8.

CH398
Clay Hawthorne Bond
A Missouri fireclay of good plasticity and fine particle size. Light fired color with approximate 10% shrinkage at cone 10.

CH518
Clay Newman Red
Newman Red is a red-burning, low-plasticity fireclay with low dry strength. It's useful in plastic and casting bodies to impart red color and has powerful staining abilities.

CH378
Clay Red Art
A high-iron secondary clay used in glazes and clay where low temperature clay is required. Fired red-brown with about 14% shrinkage at cone 1.

CH615
Clay Vantage Red

CH412
Clay XX Sagger
A fine-grained secondary clay which fires to a light cream with 13% shrinkage at cone 10. Considered very effective in salt firing, and it's claimed that it works well in wood firing too.

CH402
Clay Yellowbanks United 401

CH313
Cobalt Carbonate
Used as a glaze colorant and for decoration. Dry powder color is pink, but produces blues under all conditions. Not quite as concentrated as cobalt oxide, gives softer blues. Finer particle size avoids speckling.

CH314
Cobalt Oxide
Produces consistent strong blue tones. Slightly larger particle size compared to cobalt carbonate, which can induce speckling in glazes.

CH315
Copper Carbonate
A green and turquoise colorant in oxidation. Can produce blue-greens and copper reds in reduction atmospheres.

CH316
Copper Oxide
Copper oxide is one of the oldest glaze colorants. A strong flux, producing fluid glasses. Doesn't change under normal oxidizing conditions, but may produce copper reds in reduction. Preferred for many uses.

CH317
Cornwall Stone
Cornish Stone is a type of spar used in clay bodies, giving strength while firing. Also used in engobes for its adhesive power during and after firing. Used in glazes for its low shrinkage and minimal defects.

CH334
Cryolite (Kryolith)
Sodium aluminum fluoride can be used as a source of insoluble soda flux, but fluoride may bubble through glazes, causing pinholing. May be used in small percentages as a flux in low-temperature clay bodies. Gives off poisonous fluoride gas during firing.
