Conductive Paint or Tape on the Edges??

Copper foil tape is used in leaded glass work. It might be worth a trip to the stained glass supplier.

Hey Arthur. Welcome aboard.

Not sure if it's still available, but alarms on store windows used to be made with a metal (possibly lead) foil tape. The breaking of the glass would cause a break in the continuity of the tape, which would set off the alarm. Perhaps Radio Shack or electronics supply shops might have it.
