This group of vases utilizes white Kohiki slip.

Kohiki slip was used centuries ago in Korea to thinly cover their dark clay with a layer of white while allowing hints of the darker clay to be seen.

Akira Satake took this idea to a new level with his patterned stretched clay kohiki slip creations. Fellow potters would enjoy one of his great workshops demonstrating this and other texturing techniques (https://akirasatake.com/workshops )

This variation uses a thick brushed layer of this slip and a multistep process which forms shaped crackles along the brush strokes, exposing the layer of clay beneath.

This allows glazes and stains to be added to the crevices as well.
I love the unexpected variations of the crackles which suggest waves and cracked earth.

Here are a few Kohiki and other crackled waterglass surface vases for sale. more examples are below in the SOLD area

The SOLD items below are saved as examples. While I don’t really do custom, I can make a shape you request
