At San Jose State University we are thinking of building a soda kiln.

Are you familiar with Ruthann Tudball's soda firing? She recently did some
very interesting workshops on the West Coast. She claims the soda firing is
not toxic as is salt firing, as there is no chlorine to be released. She
lines her kiln with something that may be similar to ITC and the soda does
not impregnate it. She says one can soda fire in a regular kiln and switch
back and forth with an appropriate lining. You might want to read her book
titled "Soda Firing" or some such. Maybe someone else in Clayart has been
to one of her seminars and can add information. Lesley in So. Calif.
