金箔
The first is a rare type of old master print parts of which are decorated with small thin shiny fragments of metal or quartz crystal applied to glue. Gold leaf fragments were used on some, and colour was applied before the tinsel. Arthur Mayger Hind cites fewer than ten examples as being "practically all whose location is known... all seem to date between about 1430 and 1460". All are religious woodcuts, and probably German in origin, perhaps from Augsburg. They intended to imitate fabric, which was also the intention of the related "flock prints", printed in glue on paper that had been impressed on fabrics, and then sprinkled with chopped wool.
