Miriam's Cone 6 Glaze: a variation on Lana Wilson's Textured Crawl

Nepheline Syenite       60
Magnesium               22
EPK                     18

This recipe is very similar to the original; I just replaced the ball clay with kaolin.  This seemed to make the glaze adhere more smoothly to the tile, and also gave it a pearlescent sheen.  The high amount of magnesium in this glaze is what causes the crawling effect.  It needs to be applied thickly in order to get a good amount of crawl – I applied it about 1/8 inch thick.  It can give interesting results layered over slips and glazes, as long as the base glaze is fairly dry.
