Hello everyone,
Here are the glazes contained in the Lenore Vanderkooi article by Phyllis
Blair Clark from Pottery Making Illustrated. I've rounded the numbers to
the nearest 1/10th of a percent.
Have fun testing them!

Best,

The Pottery Making Illustrated that you are looking for was actually a
supplement to Ceramics Monthly Jan. 94. I believe it was a test case to see
how the publication (PMI) would be accepted.
Since Richard Aerni has already supplied the glazes, you may not need the
article but it is always interesting to read.
Have fun.
