Stiegel glass
American colonial glass, blown in pattern moulds and painted with enamel flowers.
German-born Henry William Stiegel ran one of the first large glassworks in the American colonies in 1763–1774. He went bankrupt, but his name became the label for a whole style. Examples are in the Metropolitan Museum and the Philadelphia Museum of Art.
Materials: Colourless, blue or amethyst glass, enamel
Manufacture: The glass was blown into a pattern mould of diamonds or ribs and then expanded; some was enamelled.
Diamond or rib patterns softened and stretched as the glass was blown further.
Simple enamel painting of birds and tulips, as on German peasant glass.
