For me, I've used these for the past two years. I accidentally had a knife slip and nicked around the wrist which hasn't affected the operability, but it does let water in when I wash. I try to keep the insides dry because I had one pair of another gloves get mildewy years ago when they got wet. These are NOT SLICK! They're ribbed (for my pleasure?) and food stays in your hands. They're for food, not fire.

For hot grates and tools near the fire (pans, CI skillets, etc) I use the Ove Glove. But any of the heavy knit gloves, I think, will do. you can throw these in the wash.
I bought a pair of the silicone gloves once. I think they're in a box someplace in the garage. Don't waste your money.
For fire, I use my firefighter gloves which are highly resistant to heat, but very expensive. Shelby's are the biggest brand, running about $100, depending on features. If you need true fire gloves, look for the words "NFPA rated" and "Structural" -- they'll withstand much higher heat.
"Rescue" gloves are basically advanced workgloves -- better dexterity, but not much heat resistance.
"Wildland" gloves are closer to Rescue Gloves, sort of in-between the two, but don't have the high heat-resistance.
