ARTIGAS GLAZE 681
CONE 8-10
OPAQUE GREEN GLOSS

custer spar 45
whiting 20
epk 14
silica 12
cobalt 1.5
chrome 6
tin 10

there are no difficult materials in this glaze if the ware is fired correctly
and if care is taken with the mixing of the dry materials

May not be stable at cone 8 - it depends on how well melted it is. The high
amounts of chrome may be a problem - affecting stability - so it should be
tested for chrome release if used as a liner glaze.

The expansion is still on the high side so it will craze on many bodies -
especially porcelain.

Cobalt oxide or carbonate?

Chrome fuming will affect many glazes with tin in them and contaminate the
kiln for future firings.

Dear Hal Mc Whinnie,=20

Thank you for providing information about Jose Artigas. that puts a much =
clearer and more acceptable spin on what you are providing to Clayart =

into frit form.

Are there any biographical accounts written about him or books =
illustrating his works?
