Can I use glass separator as high fire kiln wash?

A glass separator is made of minerals that do not fuse at high temperatures. You can use Paragon's glass separator as a high fire kiln wash. Paragon’s glass separator and high fire kiln wash are both designed for temperatures up to cone 10 (porcelain and stoneware). The only difference between them is that the glass separator is ground more finely so that it will leave a smoother surface on the underside of glass pieces. (Please note: This information may not apply to other brands of glass separators. Ask your supplier to be sure.)
