 Homemade refractory recipe
I've been reading about used oil burners for casting and trying to come up with a recipe for some homemade refractory for the burner. I have portland cement and perlite kicking around the farm and some hard firebrick. I was wondering if, while it will be a fair bit of work, crushing up the firebrick would work for the refractory or will I still need new fireclay or benntonite clay? |
