Here's my slip/glaze contribution. As with all glazes
and slips it all takes physical testing to get there
from here. The comments section will help reduce that
time. The clay content is 50% with dolomite inclusion
and 3124 to flux the materials. High AL203 low SiO2
with a low mid B203 level. Recommeded for exterior
decorative pieces when used as a thinned down glaze or
as a slip when used as a paste or thickened.
