Most glass is mostly transparent to microwaves. Not all. I’ve broken several glass objects in the microwave over the years, from the glass absorbing the RF and getting unevenly hot. Bang! Plain glass. The pyrex glass used in cooking implements, such as our measuring cups, will heat up, but I have yet to break one of those. Then there are some glazes on ceramic mugs and the like, that will heat up. Then there was the Arby’s bag with the sandwich in it. I put the whole thing in the microwave. They wrap their sandwiches in that foil coated paper. So yeah; I ended up stomping out the flames on my sister-in-law’s kitchen floor. For some reason she failed to see the interesting novelty and the humor in it. The only real downside was the loss of a good sandwich.
