If you use custer feldspar and/or the following clay bodies: 112, 130, 153 192, 205, 211, 225, 240, 240G,257, 259, 306, 378, 437, 508, 621, 760, 762 and 768, please read!

Our Custer feldspar supplier, Pacer Corporation, has informed us that they will terminate production of 200 mesh feldspar and exclusively produce 325 mesh feldspar on July 1, 2015. We expect that this change will slightly affect absorption and shrinkage rates.  We will post the new data as soon as we finish testing. We strongly suggest that users do glaze fit tests.
