White crackle with technique –Susan Stefanski Amann

  The clay body is standard 239.

Underglazes are Amaco Velvets.

  Glaze is: Colemanite (Gerstley Borate) 80%

and Custer Feldspar 20%

 

Emerald – Cone 5/6 ox –Kelly Moen

 

 

Emerald – Cone 5/6

Gerstley Borate – 49

EPK (kaolin) – 19

Flint (silica) – 32

Chrome oxide – 2

Cobalt Oxide – 1

Bentonite 2%

This glaze has to be applied much thicker

than you would expect a glaze to go on.

Almost like a thin yogourt. The mug in the illustration was fired to cone 5.

As you get hotter the green becomes more uniform and “greener” much like the area on the edges of the handle
