Brown/black, shiny glaze.
This is a really dependable temmoku glaze.
Black when thick, brown when thinner.
Works well in salt, where it turns a runny yellow green if salted heavily.

Opaque light yellow glossy to matt.
This glaze is a good salt liner.
Add approximately 1 or 2 tablespoons of Epsom salts dissolved in a little warm water to 5 gallons of glaze to help keep the glaze suspended.
Very nice on stoneware clays.
In reduction firing, with no salt or soda glaze, it makes a beautiful yellow matt with medium to slightly thin application.
Too thick and it gets shiny!
Too thin and it will be brown!

Opaque red orange brown slip or engobe.
Apply thinly to bisqueware, slip should be very thin.
Dipping or spraying works well.
Dampening the bisque will aid in adhesion and in getting a thin coat.
C-Red clay would be a good substitute or you can try your local earthenware clay.
If possible, use clays low in magnesia and calcia.
I often add more red clay to this, maybe double the amount, for a darker flashed color in wood or soda, sometimes just mixing in some red clay terra sigilatta by eye as I thin the slip for spraying.
Like a rubber band, the truth weakens the more it is stretched. |
