How is stained glass made? historically where was stained glass typically used

this is a good question! i'll do some research and come back when i have the answer!

so, not gonna do the actual thing because that's just laziness for an easy assignment like this.

but someone that has a lot of information and interesting details about is picasso. you can easily write a 500 word essay about him and how overtime his paintings of himself got more and more deformed representing that he was forgetting what he looked like and that was from memory.
