I would like to build a new salt kiln, but I need to save as much energy
as I can so I don't want to use hard bricks again. I seem to remember
an article years ago in Ceramics Monthly about APGreen K23 soft bricks
being soda vapor retardant. Does anyone know about this?
I also wonder if there is any blanket material or castable that I could
use?

Paul -
Nils Lou, at his talk at NCECA, suggested Thermal Industries (Formerly
B&W) K-23 with either ITC-100 coating, or Heat Unity coating. He
recommended the ITC, despite its higher cost, because it apparently is
less likely to spall. He noted, however, that people have used the Heat
Unity coating with good results in salt kilns. The coatings not only
protect the kiln (kiln furniture, too), but also increase effiencicy by
around 1/3. (Nils - great talk. If I've screwed any of this up, please
correct me).
I just recieved my order of ITC-100. The folks were very helpful and
nice. Since you're just across town, stop by the studio and I'll show you
what they sent.

You are correct about the APGreen Brick, but it is called the GREENLITE
brick. It comes in temperature ranges from 2300 to 3000 degrees. They
have tested well against salt saturation. This is your best alternate to
the hard brick. Blanket is not a good option for this type of application.
For your nearest APGreen dealer try 800-887-5555 nationwide.
