This vintage Pyrex glass ovenware has been used for over 20 years. I think we acquired it in a thrift store in town after we bought our place in Caseville. It's a perfect size cleans up easily and is practically indestructible. The green flower pattern held up well but looks a little worn and faded.  The dish pattern Vintage Pyrex “Spring Blossom Green” pattern casserole has lead levels registering at  110,000 parts per million.
