I’m looking to cast a one piece throat for the transition from the inner and outer arch to the flue pipe. Any advice or tips. I’ve looked at some castable refractories like KS4V plus but it seems pretty dense. I’d like to go with something a bit lighter plus still strong and can handle direct flame contact. Was thinking of basalt fibers instead of stainless steel fibers to take further out some weight.
Thanks
