I know this has been discussed in the past regarding high duty vs. low duty but the cost arguement in my case is not an issue. I came across a gentleman who had a warehouse of palletized firebrick which was to be used to build an oven for Owens-Corning. The oven was never built and the bricks have been sitting there for years. He gave me enough bricks/slabs to create an oven - these bricks are KX-99 arch bricks (40% alumina) and BF Varnon slabs (9 x 18 x 4, 9 x 12 x 4.5). Dimensionally, it will be about .5" less than using standard fire bricks but I figure that's not an issue.
So it boils down to the heat issue. Some have mentioned it'll get to hot yet others have said it will keep heat longer for cooking. Rado at traditionaloven.com has said it requires just getting used to how your oven cooks. Am I wrong to assume that the bricks can attain a higher heat than low duty bricks but won't necessarily get that hot if you control your fire? It would be nice to have bricks which could retain heat for a longer period of time and minimize recharging while cooking. I appreciate any comments!
