The small diamond-shaped panes used in old cottages and in churches are set in lead strips called carries, soldered together to form the panes.
The lead is first cast into bars, and then passed through a vice, which turns them out in cames about 6 feet long.
The section of the cames resembles the letter H. The dimensions vary according to the purpose for which the lead is intended. In the size most commonly used the sides of the H are -§ inch long, the cross-bar between the sides 3/16 inch long, and the thickness of the metal about 1/48 inch.
The sides of the cames are bent down so as to admit the panes, and then turned up again, so as to form a groove in which the edges of the panes are secured.
In large windows the leadwork is strengthened by iron saddle-bars, to which the cames are secured either by leaden bands or with copper wire soldered to the cames and twisted round the iron. The saddle-bars themselves are supported, when necessary, by iron stay-bars, or standards, which are fixed in the masonry.
Fretwork is somewhat similar to the leadwork just described, but that the cames are of much lighter section, and instead of being in regular shapes, such as squares and diamonds, the pieces of glass are cut so as to form figures or other patterns, and the cames are bent round to fit the edges of the pieces.
