Crackle Shino

Here are some images that people have been asking about. This Crackle Shino is made with Bruce's Crackle (see below for recipe).

Make the tea bowl and bisque fire.

Then glaze with the Bruces Crackle (or any high clay shino) then rebisque fire (at least 1100F) then black stain is rubbed into the cracks and then fired to cone 10.

You can use any stain or iron wash or slip or another glaze for that matter.  Experiment and have fun cause this won't last!

John, look at Michael Coffee's technique. He puts Alberta slip and Chun Red under shino and get a wonderful crackle.

Lee,

I have see those but don't know the CT recipe.

Is that Carbon Trap?

Togeika said...

John, Yes, Looking at the images, I think he used carbon trap. They tend to be less refractory. Malcolm's should work. I especially like the chun red under white shino. I want to try it!.

Lee,

I think it has to be a low clay shino, like Penn State (20% clay) otherwise it will be the typical crusty nasty mess that the phrase: "shino first or the pots is cursed" refers to. Try the ones in the book , page 83, High Feldspar Shino, like Penn State, Pete's Gold, V&O, etc.
