Lead Cames have long been a feature of stained glass windows in churches and cathedrals. They consist of H-shaped sections of lead which hold together the individual pieces of glass. They are now being used more widely in modern homes both in the traditional way and in the form of self-adhesive strips stuck on to a larger piece of glass to simulate an integral came. The use of lead in this manner is attractive and lends a traditional air to a home.

A came is a divider bar used between small pieces of glass to make a larger glazing panel, sometimes referred to as leaded glass. This process is then referred to as "leading". Cames are mostly made of soft metals such as lead, zinc, copper or brass. They generally have an H-shaped cross section, although U-shaped cross sections are used for the borders of panels.
