This type of glass gradually replaced the use of leaded lights.

Sashes were introduced, which led to a greater demand for ironmongery. The most common fittings included brass pulleys (and later cast-iron) weights, sash stoppers, shutter hinges and handles and various fasteners used to fix the sashes.
