Raw Materials M-R
Suspending agent. Similar in working properties to bentonite
|Magnesium Carbonate MgCO2
Provides color and strength to glazes. Imparts opacity and can give a matt finish.
|Magnesium Zirconium Silicate
Strong opacifier. Produces soft matt finishes.
A glaze specking agent. An oxide of iron.
|Manganese Carbonate MnCO2
A flux and colorant. Produces purple to purplish brown.
|Manganese Dioxide MnO2
Clay nad glaze colorant. Ranges from red to black depending on other materials present.
Reduces thermal expansion in clay bodies. Adds to fired strength.
Used as a soda feldspar. Helps to reduce crazing when added to clay bodies.
|Nickel Carbonate NiCO3
Coloring agent producing browns, blues, grays, greens and yellows.
|Nickel Oxide NiO
Useds as a colorant similar to nickel carbonate.
|Nickel Sulfate NiSO4
Similar to Nickel Carbonate.
Provides yellows and browns in manner similar to iron.
A strong Zirconium based opacifier, no longer available. See Ultrox.
Used for mold-making, batts, wedging boards and press molds:
#1 POTTERY: High grade "porous" plaster for quality slip casting molds and general casting.
DRYSTONE: Can be used for solid of hollow applications. This plaster is a fast-casting gypsum cement that provides strong casts without the use of dryers.
DURAMOLD: Compare to No. ! Pottery Plaster! 10% longer life, 28% higher whet compressive strength, 66% stronger dry compressive strength! Much more durable!
GARDENCAST: A white gypsum cement that is perfect for freestanding, solid-cast, outdoor statuary, and takes paint well.
HYDROSTONE: One of the hardest plasters used for finished sculpture, castings, press molds (high compressive strength).
HYDROCAL: A very durable gypsum cement that works best for sculpture and architectual details.
HYDROPERM: A high-temperature gypsum used for non-ferrous casting.
ULTRACAL 30: A very strong plaster used primarily for ram-press type molds.
A lithium feldspar. Reduces thermal expansion in clay and glazes.
|Potassium Carbonate (Pearl Ash)
A glaze flux and color modifier.
(See Volcanic Ash)
A feldspar clay.
Reduces thermal expansion in clay bodies.
Glaze and clay colorant and specking agent.
|CAUTION: Many ceramic materials are toxic and should be handled with care. Inhalation and ingestion should be avoided. User should be familiar with proper safety precautions before using. M.S.D.S. are available upon request.
