Re: second post, lots of reading
Brevan,
this is an interesting topic and I currently have access to an engineer (who married my immediate neighbors daughter earlier this year and is currently next door for a week) who works out of Canada for a company who designs and builds blast furnaces all around the world using wholly refractory materials (albeit high temperature).
I will see if I can get either some specific information from him or get him to source through his company contacts regarding the positive characteristics (and also the negatives) of the differences in oven materials.
I feel quite strongly about this as many people don't have access to the quite expensive materials in some places to build an oven.
Refractory manufactures do have a agenda to make sell and profit from their goods - understandable, but these materials have only been available for a relatively short time when compared to the traditional fired clay brick.
I also realise that clays vary considerably through out the world, we might have the best for brick manufacture, and the US the worst, how it is mixed and fired for the final brick will also vary, but even with today's technology, every fired brick will be much superior coming out of a fully automated processing plant than when they were stacked in large (double garage sized kilns) and fired for 3 days with 4 foot hardwood only 50 years ago.
