At this point, armed with new knowledge, you may want to abandon the crucible notion entirely on your next inevitable rebuild and use some of the AZS block that comes out of Minteq in Slippery rock Pennsylvania. Eddie Bernard at Wetdog has been working it successfully all these years I am happy to say. Basically, you need five bricks all prefired and hopefully machine edged. I think the notion of the square crucible could be addressed by them as well. I don't know if Eddie has some sort of exclusive on that but you might give him a call at Wetdog. AZS liners aren't for everyone and have many drawbacks. It has to be considered carefully.
