This type of glass gradually replaced the leaded light bulbs.

The introduction of sashes resulted in the need for a larger variety of ironmongery with the basic fittings being brass pulleys and lead (and later cast iron) weights, sash stoppers, shutter hinges and knobs as well as a range of fasteners used to keep the sashes in the right place.
