Just love it!
Can you tell me is 'cluster feldspar' the same as either potash feldspar or soda feldspar? Or another one again?

What can I use to make the lines permanent? Won' the ink wash out?

The ink never washed out for me, but if you can use ball milled iron or some very fine colorant and then refire it to seal it in.

Nice John! Looks like an extra thick application? SG = 140-ish?
