Curiosity made me order one!
RN- would you know if the shelf can handle direct flame contact. For example a Fibrament stone cannot be place on the grill without a pan or other blocking of the flame.
As one would expect, results may vary, but I'm anxious to hear from someone else on their results.
SiC is used in direct flame impingement environments, so I'd say so. FibraMent stones are not designed to take extreme temperatures like traditional refractory materials, so the radiant heat must be kept at bay. I suspect FibraMent can't withstand the extra heat because of the fabric laminations within the stone. This is what Mark at FibraMent had to say about extreme baking temperatures: "It is not necessary for baking stones to have a temperature rating that exceeds 750 F."
So if you agree with him, it wouldn't matter.
