I have a set of stiff silicone perforated disks from 8" up to about 14" that I purchased many years ago fro QVC. They can be used in the microwave, stove or oven as covers or trivets. I leave the smallest one on the counter in front of the microwave for use as a lid or sometimes I use it to carry a hot bowl from the microwave to the table. they clean easily in the dishwasher.
