Letters written between 16 from the steward to the owner of Levens Hall in Westmorland refer to the use of ‘quarry’ glass (meaning diamond panes) in various buildings around the estate, including the stables and the clock house.The accounts for Levens Hall contain the following item: 'put into severall windos 14 squers of new glass att 2d the squer'.Figure 3 (above) A wrought iron casement with horizontal saddle bars and diamond leaded lights in Cheddington, Bucks.Note the spiral handle at the base of the casement and the plain hook stay. Figure 4(upper right)Window catches from dated houses (from ‘Fixtures and Fittings in Dated Houses’) Figure 5(lower right) Window catches from 38, Latimer, Bucks illustrating the great variety of window catches found in this house which dates from the second half of the 16th century.
This is a far more economical shape than the later square or rectangular panes, as oddments of glass – which was still a relatively expensive material – could be used up in the small triangles at the edges of the window.
Only the spring catch in the hall chamber is likely to be original.
The dairy chamber catch is late 17th century, the parlour chamber catch probably early 18th century, and the others any date up to the early 20th.
This design appears to be a later development, often appearing in late 17th century and 18th century windows.
Occasionally windows have two stanchions per light: these are for security, rather than for fixing the leaded lights, and generally seem to date from the later 17th century.
18th and 19th century casements tend to be much larger, and always take up the full height of the window.
