We're about to build a castable refractory Soda kiln and would
appreciate any comments about what mix works best. The primary
question seems to be: add vermiculite or not. In the book "Soda
Glazing" a reference is made to eliminating the vermiculite because it
made the mix too crumbly.
Also some folks use Kyanite in the mix,
which seems like a good idea as far as thermal shock resistance goes.
Finally, One mix listed an alumina cement, while others just added
Alumina Hydrate - any advantage.
Has anyone got one of these kilns that has withstood hundreds of
Thanks for your help!
