Window Glass Edge Piece


Jamestown Rediscovery

Window glass edge piece This piece of window glass that was found in Pit 1 is an edge piece from crown window glass. Crown windows are blown into large rounds which are then cut up by the glazier into pieces that are held together by lead in a window frame. The edge pieces are too thick to be used and are discarded as waste glass known as cullet. Cullet is an ingredient in the making of glass because if old glass is thrown into the new glass mixture, the temperature of the furnace does not have to be quite so hot and the production time is shortened. This is why we recycle glass today! The edge piece is at Jamestown, then, as cullet to help the glassmakers (who arrived in 1608) make glass. It is not part of a window that the glassmakers made.
