Here is a picture.

Picture does not do effects justice.  Glaze is very shiny looks more satin matt in picture.

I will mix it up and give it a try and let you know Randy. Looks good. I have done a few more glaze tests recently and will post the results as soon as i get time. Is it on white clay? Did you do a controlled cool? Thanks for sharing.

Sounds good. We need more sharing of these types of glazes.

Leach Blue base also makes a great clear put on thin no crazing on most stoneware.

can you post some pictures of this please?


You want me to post pictures of a clear glaze?  Put on two thin coats.


Special Red iron oxide used in C Harris Tem can be obtained from Ceramic Supply.
