I bought this stone, because in our kiln always the plate which deflects the flue gases, ie just above the fire, always breaks. The manufacturer has replaced me on warranty, but said that this happen repeatedly würde.Auch an info that I would like to know before buying. After I had to replace two more at his own expense, I was a little upset. Since I am not want to resign to swap the board every year I once tried this stone and behold he holds and holds and holds. I have tailored it to my firewood circular saw and also has wonderful funktioniert.Mit the remains, I then once tested a little how robust is the stone. So there is already a significant difference to my original product.
Can only recommend buying, I think I will now replace gradually all fireclay brick through this. Full 5 stars!
