Firing ramp:
100c p/h to 600c (212f - 1112f)
150c p/h to 1140c (302f - 2084f)=20
80c p/h to 1240c (176f - 2264f)
10 min. soak
cool down max. to 1100c (2012f)
Hold 1 hour
Shut off kiln

60 Nepheline Syenite
22 Magnesium Carb.
18 Ball Clay

Note: All raw materials are measured up or down to the nearest half =
decimal. =20
Colorants or additives to a 100 gram test batch are measured in percent =
to the 100 gram test batch.

Application is crucial to get this glaze to crawl. It must be applied =
thickly enough that there are slight cracks in the dried surface. I =
brushed it on.

Glossy, white islands, like drops of school glue (Elmer's for the =
Americans). The individual islands were different in overall sizes, =
from 1cm or less to a healthy 2 centimeters in diameter. They are =
varied in shape from round to oblong. The islands sit high above the =
clay surface and are smooth to the touch. =20

Over a commercial 04 black
The glaze melted into the glaze, still forming distinct islands. The =
islands' edges are more geometric, like oatmeal, however still very =
distinct. The are not as raised as the Texture crawl by itself, but =
still raised about the surface of the black glaze. The black glaze =
pooled and formed a border around each island.

Over Lili Krakowski's Albany Slip substitution
The glaze is more covering and is more lichen like as opposed to raised =
islands. The overall surface is a labyrinth of white flattened shapes =
of all forms, revealing the slip only where the shapes are separated by =
their crevice like borders. The glaze lies almost flat, but has a very =
distinct lichen pattern. Like the pattern of our brain tissue.
