How to use: You can use a flat blade to gently scrape away parts of the ITO film on one side of the glass to create 'traces'. Laser cutting can also be used to pattern the film. To make contact, use conductive inks, paints, copper tape with conductive adhesive, or alligator clips instead of soldering. Precautions: Since it's glass, be very careful when handling it. Any scratches or nick - lines can cause the glass to break along that line. Maintenance: Store the glass in a dry and clean place, away from sharp objects that could scratch the ITO film or the glass itself. Avoid exposing it to extreme temperatures and humidity.
