Is fire clay and fire rock the same thing? I just got around to getting the supplies rounded up to make a small foundry and noticed when I got home they give me fire rock instead of fire clay. Reading the label says it's a mortor for laying brick fireplaces.
If not the same, will this stuff work? I'm mixing up the home brew refractory, Fireclay, sand, perlite, and portand cement.
Made the propane burner already, that thing is cool. Well..........hot.
Have a great day,
