I know there's a point (cone 10?) where unglazed porcelain is food safe because water absorption approaches 0%. The inside of the snake is not smooth and I don't think I can glaze it adequately without plugging the hole. I thought you could layer glaze at any temp as long as you didn't exceed the temperature capability of your lowest material - OK to low fire glaze over high fire clay or high fire glaze, but not to high fire glaze over low fire clay or glaze. Isn't it the same as using a cone 018 gold overglaze over a low or high fired glaze? Looks like I may need to try some test tiles :)
