Hello list,
A friend of mine has acquired a used Bailey kiln and is thinking about
using it for salt firing. It has a soft brick interior. She asked me if
it would be OK to do that, and if there is any kind of refractory coating
she can apply that can make it work.
My reply to her was that soft brick is not appropriate for salting. I also
mentioned ITC coatings and said I believe that either Neils Lou or Mel
Jacobson had experimented with it and that the experiments did not
indicated ITC to be a satisfactory coating for use with salt. Am I right
in this advice? Does anyone have any better advice, or a better coating,
to offer her?
Thanks in advance for all the replies I will get...

Richard -
ITC coatings do wonders in some kiln applications, but they do not protect
against salt. I do not know of any coating that allows salting in an IFB
kiln. Salting will result in serious sponging and spalling of the IFB
hotface.
We have an IFB soda kiln lined with ITC, and it holds up pretty well. We
use it quite heavily (30-40 firings per year) and we have to rebuild it
every five or six years.
Best wishes -
