Purgator Posted November 3, 2020 Share Posted November 3, 2020 Hi, I am new here and want to build a second a better gas forge. While looking my nearby hardware store i stumble on rock wool that is cheaper and can take up to 2150F. I know people usually use ceramic wool is there any reason people go for ceramic wool over rock wool? Quote Link to comment Share on other sites More sharing options...
