One other thing people recorded with care was, somewhat surprisingly, window glass. Other than in churches and a few wealthy homes, window glass was a rarity well into the 1600s. Eleanor Godfrey, in The Development of English Glassmaking, 1560–1640, notes how in 1590 an alderman in Doncaster left his house to his wife but the windows to his son. The owners of Alnwick Castle from the same period always had their windows taken out and stored when they were away to minimize the risk of breakage.
