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.
