I have a pair of army green 100% wool gloves that I'd be willing to ship off to you for $7. However they are almost 3 oz, so I don't know if that meets your requirements. I bought them for the exact same reason you are looking for a pair. I bought a pack of them as that was all I could find that would give me enough insulation in 100% wool for cooking over a wood stove.
If you decide to go with something else, make sure you get 100% wool and not something that has a little something else mixed in that will melt. There are many places out there that sell "wool gloves" that have some polyester or acrylic mixed in. Just a heads up for you.
