[Tig Dupré]

Thanks, Ron.  I hadn't realized it was underfired.  I'll do some more testing!

Thanks for posting this Tig,

It's not a good liner glaze so best not to use it where food can be in
contact. It's what we call an underfired matte and is not properly
melted at cone 6.

I'm not criticizing but some potters may not be aware of the problem.
