The glass in the new Mojo as well as the original glass call by River Valley Game Calls is also as Scott put it, straight up glass....it's then acid washed to roughen the surface for use with a stricker to create the friction....many glass calls are sand blasted which creates a more rough surface.

The surface of the Mojo and Original glass isn't as rough as a sandblasted glass call, it's realitely smooth other than enough texture to allow the friction between the glass and the striker. Once acid washed, sandpaper or scratch pads can roughen it up when needed. When wet, the call still produces great sound with a carbon, glass or acrylic striker....when dried and touched up with a scratch pad, you can go back to the wood striker although the carbon, glass and acrylic still work making it an all weather call.
