NYcBBQ, the gloves you describe sound like the same ones I use. (I was the one who originally posted about the Wells Lamont PVC-coated work gloves.) They may not specify any heat resistance on them, but I will attest that I have comfortably used them removing hot grates from the smoker, moving hot thermometer probes around in meats, and for flipping large briskets and butts. Thus far, no damage to the coating on the gloves, and the heat doesn't come through to my skin. As I've said in other threads, I'm sure there's a limit to the heat they can take, but I haven't found it yet. Of course, then, I haven't picked up a flaming log or red-hot coal and held them in the palm of my hand for any length of time, either... now I DID grab one end of a burning log in the offset once and quickly rearrange it on the fire, but no damage to the glove or heat felt through the glove.
