[Clayart] Replacing bentonite

[David Woof]

Hi Jeremy,
A typical Kuan Crackle formula contains Neph Sy,  Potash Feldspar,  Silica, and Calcium such as Whiting.
These ingredients alone, mixed into a Glaze slop (slurry) will soon sink to the bottom of the glaze bucket without the addition of a mechanical mineral suspension agent such as Bentonite.
 Bentonite excels as a suspender as well as being the most often addition to effect higher plasticity which supports ability to provide colloidal dispersion, and thus to effect and control the rheology of the glaze slop.
Bentonite also works as a binder to hold the materials together and make a more durable dried adherence to the pot.
Misneach,
David Woof.....................................................................................................................................................................................

Subject: [Clayart] Replacing bentonite

Hello,

I’m starting to work on creating a Kuan crackle glaze. My starting recipes
have bentonite in them and I don’t currently don’t have bentonite in my
workshop and would like to keep it that way otherwise I just keep adding
new materials all the time to my list of raw materials.
Would you have any suggestions how to go about replacing bentonite in a
glaze ?
Thanks and all the best,
Jeremy
