These gloves are great! I use them to manipulate a hot metal tube during a supercritical extraction process. I used to have to stop and wait (15 minutes) for the tube to cool enough to handle through work gloves, but this added complexity. Now, with these gloves, I grab the tube while it's hot (~70C), unscrew the tube, handle it, reverse it, replace it, and all within 3 minutes of needing to do the switching. I can barely tell I am holding anything even warm with these gloves on.
