The Glass-Master tool allows you to achieve excellent results when working with copper foil. It can also be used for lead window work. You can use one of the patterns supplied with this kit or create your own pattern. Simply place a coloured piece of glass over the pattern. Use an oil filled glass cutter to score the glass along the required line. Using pliers apply pressure down to cut the glass. Repeat the above procedure until you have all the pieces of glass you require. Apply copper foil to the edge of each piece of glass, then simply solder all of the pieces together to produce your work of art.
