Glass screens dont look like metal screens. I have one in my hammer and basically all it is is a very small bit of blown glass sort of in the shape of a "jack" (like from the game where you bounce the ball and pick up the jacks). It sits in the bottom of your bowl and kinda half plugs up the hole, making it smaller so ash doesn't fit through but smoke does. They work great. The only problem is the first couple of times you cash your bowl the screen will probably fall out so be careful. Once there is enough sticky resin in there it wont be a problem.
