containing yellow ochre taken from (don't laugh) the Reader's Digest 'Craft=
& Hobbies'. Among other things, I taught myself how to bookbind with sewn=
signatures, hard covers, etc. using only the information found in that=20
book, purchased for $5 Canadian in a seconhand store about 10 years ago,=20
and the pottery section is really quite detailed.
Gerstley Borate 80
Potash feldspar 20
Yellow ochre 7
