warning...
cutting 1/4 inch thick glass is pretty difficult to do well the first 30
times!
Window glass or thin mirror tiles are easy to cut with a hardware store
glass cutter, and you might want to try practicing on them first.
The thicker stuff requires a very steady hand, even pressure, and a good
straight edge.
This is especially true if your first few cuts have to be on a very big
piece.
It has to be all one cut, you can't stop and start again if you want a
good edge.
