Dear Arnold,

Here is the recipe I use for raku crackle:

Frit 3134 90
EPK 10
I also add a handful of epsom salts to the glaze bucket.

Pull from the kiln when the glaze has matured to a glassy finish. Place =
in reduction chamber (commonly known as trashcans in most places) to =
blacken the exposed clay. This is really just a clear glaze that is used =
on a white clay body. It is glossy and a good base for colorant =
additions.

If you experience problems with the glaze bubbling towards the end of =
the firing, turn down the flame and soak the kiln until the bubbles =
smoothe out and then bring the temperature up again before you pull the =
pot.

Happy Rakuing!
