Low vs. Medium Duty Firebrick

Frustrating

I think the different duty firebricks weigh different- the ones we're supposed to use in the oven plans (low-duty, I think) should weigh about 8 pounds each. A little more or less is ok, they do vary a little in size. Mine aren't quite the same width as the ones in the plans, so they're a tad lighter. Not sure how much more the high and med. duty ones weigh.

If you have a local concrete or brick supplier, they really should have the heatstop in bags. If they don't, they ought to be able to get it, although it's expensive.....

One would think. Unfortunately, the local brickyard has been very unhelpful. They have not even heard of the HeatStop 50 (powder type, in a bag). Several phone calls, and they won't even try to get it for me. It seems residential customers are not worth their time. Detroit is 90 miles south, I may have to make a trip this week.
