Product review (5 stars): Using these for my solar oven
I used these to cover the inside of my solar oven.  I did not want to paint the sides of the oven black because of the toxic fumes.  I purchased these oven liners since they are designed to be in contact with food in high heat environments and contain no chemicals, so they were a logical purchase.  So far there are no weird odors inside the oven, so I feel confident they will be up to the task.
