Cast quarries (sometimes also referred to as 'stamped' or 'pressed') were made in the nineteenth and twentieth centuries by pouring glass into patterned moulds, producing designs of stylised flowers or leaves, or copies of medieval bird quarries. Glass-painting pigment and yellow stain were then applied to the indented pattern, and the glass was fired in the conventional manner. Once very common, this type of glazing is becoming rare. The London firm of James Powell and Sons acquired various patents for this type of glass and also sold pre-made quarries to other studios to use in their own windows.
