A traditional deflocculant, often used with soda ash.
Mixing amounts vary, but a general guide is to make a small, diluted amount of sodium silicate to water, 1 to 4 (water) and then use this as a tiny splash which will be anything from .05% to .3% of the dry weight of clay, usually with a similar amount of soda ash.
We have not tested this deflocculant with our own powdered casting slips but as a general guide, use 140’s for stoneware, 100’s for earthenware and 75’s for bone china. However, this can vary due to the plasticity and contents of your clay body.
