He everyone. I'm using ^06 glaze on stoneware tiles I made, for my wooden table. No food will be eaten or prepared on the table top, so I just wanted to find out what without all think. Do I fire the glaze at ^06 or^ 6? Thanks in advance everyone.
P.s. I don't have access to the test kiln to test the results.

If you fire cone 06 glaze to cone 6, it will melt off your tiles and fuse them to the kiln shelves. The maximum you can fire to is always the minimum temperature material.

[Marcia Selsor]

06 glazes at ^6 will run or blister and boil at the higher temperature. Go look at a Cone temperature chart. You are using a glazes that mature at 1830 or so to a temperature of 2230.

If glazes are 06, then that's as high as you can fire the glaze.
It will not vitrify the clay, however.

Firing to 06 obtains porous and relatively weak tiles, so it is recommended not to use the table for outdoor conditions.

Low fire glazes don't often fit well on stoneware clays. Potential for lots of crazing or even shivering. If you want to use low fire glazes, it's best to use a low fire clay.

Perhaps you could first fire the unglazed tiles to ^6 in order to vitrify the clay, then glaze them with your ^06 glazes and fire them the second time to ^06. This will mature the glazes without over firing them and the clay will be vitrified, too.

You'll have a hard time getting the glaze to adhere to the vitrified tile during application. It's possible, but difficult.
