I'm trying to build my oven this summer on a REALLY tight budget, and since I work at a university with a big ceramics and art program, this summer I can pick the best used firebrick I can find from a kiln rebuild. Now, this is super duty firebrick, 40-44% alumina, 49-53% silica (I'm putting together information on this stuff at my site). My reading indicates the higher alumina may tend to burn bottom in the hearth; but I'm wondering if there would be any problems using it in the dome?
No announcement yet.
(free!) super duty firebrick for the dome?
