Cut glass wine glass made of lead glass. Lead glass, commonly called crystal, is a variety of glass in which lead replaces the calcium content of a typical potash glass. [1] Lead glass contains typically 18–40% (by mass) lead(II) oxide (PbO), while modern lead crystal, historically also known as flint glass due to the original silica source, contains a minimum of 24% PbO.

Leadlights, leaded lights or leaded windows are decorative windows made of small sections of glass supported in lead cames. The technique of creating windows using glass and lead came to be known as came glasswork .
Came glasswork includes assembling pieces of cut and possibly painted glass using came sections. The joints where the came meet are soldered to bind the sections. When all of the glass pieces have been put within came and a border put around the entire work, pieces are cemented and supported as needed. [1]
Leaded glass may refer to: Lead glass , potassium silicate glass which has been impregnated with a small amount of lead oxide in its fabrication Lead came glasswork , glass panels made by combining multiple small pieces of glass, which may be stained, textured or beveled, with cames or copper foil
The American glass manufacturers also had to compete with English glassmakers. By 1740, English glassmakers produced good quality window glass and some of the best lead crystal glassware available. English trade restrictions caused most of the glassware purchased in America before the American Revolutionary War to be English–made. [70]
Window glass was produced throughout the period on a small scale, in the form of crown glass and broad glass. [ 3 ] [ 11 ] This was predominantly made from green glass throughout the 16th century. [ 3 ] [ 6 ] While rare in the early 16th century, glass windows soon became a symbol of increasing wealth and status.
Hinged at the top: awning window. Throughout Britain and Ireland, casement windows were common before the sash window was introduced. They were usually metal with leaded glass, which refers to glass panes held in place with strips of lead called cames (leaded glass should not be confused with lead glass, which refers to the manufacture of the glass itself).
The channel runs the length of the came. H-shaped came has 2 back-to-back channels that hold adjoining glass pieces in position on the interior of a stained glass panel. It can also be used as a border came in certain situations. U-shaped came has only one channel and is used as a border around the perimeter of panels.
