It's a non-asbestos heat proof pad, rigid, one quarter inch thick. It's off white with sparkly bits and I need to mill a fancy insulating washer out of it.

Anyone know this stuff and what it is made of? Came without a HazMat sheet. It feels like a cross between MDF and a ceramic wall tile.

Just wondering if I need to take extreme dust precautions and cut under water? :confused:

When in doubt, take the safest route.

I think I know the material you are talking about. If it's the material I think it is, it's really brittle and hard. I have no idea what it is.

Good luck and be careful!

I woke up this morning with a chesty cough, luckily I hadn't cut the whatever it is yet or I'd have been worried :)
