So I purchased a few more medium duty fire brick to finish my dome as I was running short. Thus is my thrid purchase, two from the same vendor and the final batch from a new vendor.
The first vendor had two different colors, both batch one and two had a mix of each color. They are differences in tone, one is more orange while the olore is more yellow.
The third batch is quite a bit different from the other two, almost purple.
i think this third batch also seems to have a different texture, the first two are more corse and pitted. The thrid batch is very smooth. I also believe the thrird batch is easier to cut. The dry weight appears to be pretty similar.
So I'm wondering, are the all really medium duty fire brick? I am wondering if their thermal properties will be similar.
i could return batch three and go back to the original vendor but I though I'd check to see if there's a recommendation.
