Obviously, this glass lid cannot take the heat, for when I removed it from the heat, it instantly exploded into thousands of bits.What I was preparing had to be dumped, since it was full of glass, glass everywhere.Junk, pure and simple. Check the warranty on the lids...N o W A R R A N T Y o n L I D Sso, there you have it.Maybe a nice all-metal hubcap from a '64 beetle will fit.
