it may be a bit much as far as gripping with it. I have used 1 layer of jeans (recycled) fabric and one of batting. for handling a roaster coming out of a 450 degree oven I think I would want either the insulbrite or 2 layers of batting with denim in the center. like someone said-try it. potholders are small enough that you won't be out much if it is not enough.
