everything except the borax was obtained from great lakes clay located
in carpentersville, illinois.

the grog is a coarse grog, i do not remember the mesh.

the original refractory stood up for melting aluminum, brass, zinc, and
bronze. i never attempted to melt cast iron in these crucible furnaces.

i glazed the lining in the beginning with a mixture of ground glass,
fire clay, and borax.

1 quart of ground glass 
1 pint of fire clay
1 cup of borax
with enough water for the consistency of thinned paint.

the glaze also stood up well.

overall, i have been pleased with the lining. i am open to other
possibilities and curious as to what other people have used for their
furnaces.
