  • light duty fire bricks as an insulation

    My cousin dismantled an old pottery kiln. He offered me the fire bricks. They are very light in weight and falling apart almost into a powder. So, there's no chance of using them for my dome build.

    I'm wondering if these could be used as an insulation. Crush them with a sand tamper and use in place of perlite (in a Portland Cement mixture) on the hearth under my floor bricks. Or, should I just help him throw these away??
