Vintage Leaded Mottled Glass Four-Pane Window Sash

This is a rectangular wooden window sash featuring four distinct glass panels, each containing leaded glass work. The construction consists of a solid wood frame with a heavy white-painted interior finish that shows significant age-related wear, including chipping, peeling, and loss of paint (especially along the muntins and the bottom rail), revealing the underlying natural wood. The glass inserts are of a decorative 'mottled' or 'hammered' texture, which provides opacity while allowing light transmission, characteristic of late 19th to early 20th-century residential architecture. Each of the four panes contains a central quatrefoil or petal-like motif formed by curved lead cames, set against a background of rectangular glass segments. The lead caming appears to have a dark, aged patina, suggesting it is original to the piece. The overall condition is described as 'architectural salvage' quality; there is visible weathering on the frame and the glazing putty may be brittle or missing in sections. This style is consistent with the Arts and Crafts or late Victorian period (circa 1890-1920). No visible maker's marks are present in the image, but the artisanal quality of the hand-leaded glass suggests professional craftsmanship from a local glass studio of that era.
