Cast linings for waste oil forges

[J.Marsillo]

Anybody using them? What kind is the best? After a year of light use on my WVO forge the kaowool/bubble alumina is pretty beat up...plus I get alot of build up in the bottom of the forge.
I know there is a pretty significant warm up time with the castable linings vs the koawool but when I light that baby up i'm in the shop all day anyway...

Darren Ellis sells Mizzou and Kast-O-lite . You can cast your own liner easily.
