Notes

The company was introducing this material during late 2006 and calls it "a high quality potassium/sodium/calcium aluminum silicate ground to 325 mesh for ceramic applications." "It offers a high potash and low iron oxide content per unit of alumina and is particularly suited for use in glazes".
Cone 11 fired flow tests beside MC Na-200 show that this does not melt nearly as well.
The melt flow is whiter than G-200 and much whiter than Custer.
