I found the following recipe online for castable refractory...
"By volume, it is 3:3:4 Portland cement:perlite:silica sand, mixed together thoroughly, then combined with 4 parts fireclay. The dry ingredients are then moistened to the texture of “stiff cookie dough,” packed into a form, and allowed to dry thoroughly before bake-out." This attributed to backyardmetalcasting.com.
Can anyone comment on if this is a workable mix for stove components?
