Pioneered by Ben Franklin, I don't think it has any forced air mechanisms though. I do know however, that the glasss harmonica or harmonium uses high quality crystal for producing sound, much like when you see those dudes playing wine glasses. Those are high quality crystal goblets. The glass initially was rotated much like an old sowing machine functioned, with a foot pedal crank. Newer or modified glass harmoniums use an electric motor. These instruments are very expensive, Im not even sure if anyone makes comercial ones for sale. If someone did though, it would cost alot.
