ABSTRACT:
A device for fracturing glass along a scoreline is disclosed which is particularly useful for forming glass pieces of irregular shapes, such as those utilized in stained glass artworks. The device has a convexly curved fulcrum element attached to one leg of a "U"-shaped manipulating member, while a pressure block, having a concavely curved planar surface facing the fulcrum element, is attached to an adjacent leg of the manipulating member. A force exerted by the pressure block and the fulcrum element on a scored glass piece located between them causes the glass to fracture along the scoreline. The device also has a glass support surface which supports the glass while being fractured, and collects and retains the minute glass chips generated by the fracturing process.
