I work in a Mohs lab. I have been working in my cryostat for 3 years and haven't had a problem.
We are able to us 'surgical' type gloves. They are thicker and contain your body heat much better. I have sometimes been working in the cryostat with just blue nitriles and definitely notice the difference. We also wear barrier gowns so maybe the extra heat retention helps our hands stay warmer. I also try to touch the metal areas as little as possible. I use forceps (room temp) for tissue manipulation. The thin gloves you are enquiring about actually have no finger tips, so I don't know how much they would help you. It is also important to keep a bottle of lotion around. Specially as winter is setting in. Keeping the hands moisturized helps protect your hands from the cold too. If you use both hands for slide stability during section pick up, you can rest your elbows on the outside frame of the cryostat and not need to touch any of the metal.
Hope this helps,
