What glass is this? Where did it come from? What's it look like? What is it doing to the cat? WhoooooOOOOOOoooo! All is shrouded in mystery. Dark and spooky mystery, which is our favourite kind.
Seriously though, obviously someone forgot to tell us what kind of glass to use. So blame them, and use whatever kind of glass you want.
