Glass/Clear Tea Pots

Hello. I have a couple questions about glass or clear tea pots. Are there glass tea pots you can use on the stove top or do you have to add hot water to them to steep the tea? I was gifted a flowering tea for Christmas and I've never had it before. I thought a clear tea pot would be a nice addition to my collection.

My second question is (and forgive me if this isn't allowed) what brands or places would be best to buy one from?
