Found these awesome gloves that are supposedly rated to 480 degrees. I used them today to find out. I cranked my MAK to high, then put on the gloves to grab the hot grates and move them around while I cleaned up the MAK. I did not feel any heat through these gloves. I like these gloves because they have fingers to help manipulate things very easily, and are great for moving around hot grates. Just thought I would share.
