Georgies
offers a wide variety of raw materials for clays, glazes and other uses. If
you don't find the materials you need, please contact us. We may be able to
get it for you OR suggest suitable replacements. The Occupational Health &
Safety Administration devised this color-coded numerical ratings system to
quickly and easily summarize the levels of risk through various means of exposure
to potentially hazardous chemicals. Material Safety Data Sheets contain more
detailed information about any risks posed by chemicals or raw materials,
along with handling, cleanup and first aid instructions. Georgies maintains
a library of MSDS forms for the materials we sell. To request copies, please
contact us by phone, fax or email.

CH355
Silica #90 (200m)
High melting point. Increases hadness and resistance
to wear. In glaes, it decreases thermal expansion, but increases thermal
expansion in clays. Raises the melting temperature in glazes. Very fine
powder, finer than flour. |

Silica Carbide FFF
Extra-fine silica, used in small amounts for local
reduction in glazes. Encourages glaze effects llike cratering and speckled
reds. |

Soda Ash
SODIUM CARBONATE acts as a deflocculant in reducing
the water of plasticity in slip bodies. Increases workability and strength
and reduces shrinkage. |

Spodumene (Australian)
A source of lithia and a flux which helps develop copper-blue
tones. Replaces feldspar, reducing vitrification, temperature and shrinkage.
Used in clay bodies to reduce thermal expansion. |

Strontium Carbonate (Fine)
Recommended as a substitute for barium carbonate, but
we also recommend testing it first for that use. Pat Horsley finds that
75% of the amount of barium called for is ample. Also often causes color
loss. Try blending strontium and barium for a beautiful, unexpected glaze. |
