How can I tell if a glass saucepan lid is oven safe?

I have a set of saucepas.
I recalls from when I got them that the silicon handle is oven safe, so that you could put them under the grill to finish.
But I don’t recall if the glass lid is also oven-safe.
Its handle is also silicon, but that might just be to match

I am considering if I could use it to cook bread in the oven, as the particular bread I am using calls to be cooked in something with a lid, e.g. a cassarole dish, and my dutch oven is too large.
