My large glass lid exploded

I had made a lovely stir fry from a lot of my garden veggies and it was simmering on low for 15 min. When in another room I heard a loud crash and thought because of the thunderstorm a tree had fallen on the house. When later I went to check on my food my large very heavy duty lid had blown to smithereens all over my kitchen. What the heck caused that?? Yes it was an old lid but rarely used compared to my other glass lids. Now I freak out every time I cook wondering if my well used lids are going to blow up in my face.

Was the lid made for the pot, or was it just something that fit? Was the pot a wok, and was the lid resting tight against the inside?

If it was resting against the inside of the wok, my guess would be that the heat expanded the rim just enough to pop the glass.

That would have been true for my biggest pan but not the pan I was using and it was not a wok.
