slip glazes/ advice for albania

I know well that Albany Slip has disappeared
from use. While searching my area for a natural clay
body I noticed that one test became pretty brittle
from an ^010 bisque. I applied some to a test tile and
took it up to ^10 and was pleased to see the Albany
Slip look. I was thinking that Abania must have a variety
of clays which could be used for a very simple glaze. Mine
turned dark honey brown during ^10 oxidation and took
on some wonderful yellow breaks over texture in ^10 salt.
That same clay body can be thrown right out of the ground
by simply removing bits of roots. . .it's a great terra
cotta body and also makes a nice buff terra sig when mixed
50/50 with ball clay or by itself for that matter.

I enjoy finding usable material. I hope you have
success in your search. . .
