All my Pyrex lids are plastic. I'm away from home at the moment and can't check, but some "search engine research" suggests BPA-free #7 (the "other" category) plastic. I've seen glass lids with silicone seals, but never a fully silicone lid. I'm not spending a lot of time microwaving those lids, though. |
