Q: I like the color and the sizes of these lids, and plan to use the large ones to cover my pot on the stove top. Unfortunately these are not 100% silicone and contains fillers as you can see in the pinch test. Google search shows silicone products containing fillers are not recommended for use under heat.
A:
Failed pinch test, not 100% silicone contains fillers
