No, I can't say that I have heard of that........thick padded cloths were used to take stuff from the oven, but they were usually made up from other discarded household textiles.
Bits of old towels folded and stitched to give the required thickness....you were posh if you had oven gloves.
I think my grandma had asbestos fingers...she used to hold things that were very hot without seeming to suffer any ill effect...but warned us against trying the same things.
