Hi Martin
Hi Keith et al,
I used Perlite mixed with refractory cement in my aluminum casting
furnace. The walls saw temperatures surpassing 2000F, it was working
well. The mixture was 50/50, and the perlite is very light-weight,
reducing the overall mass of the structure.

Perlite gives very similar results to rice husk ash. Michael Allen and I
discussed Perlite in this context when I made that page on rice husk
ash. You used the same ratio of cement as I do with RHA, after trying it
20 different ways in tests.
Regards
Keith
I wouldn't mind using RHA for such a thing, but I don't think I'm within
1000 miles of a rice field.
