APPLIED BLOBS AS DECORATION
During the making of vessels, blobs of molten glass were dropped onto the surface creating a raised decoration, sometimes called prunts. It was an option for the glassmaker to leave the blobs in an irregular smooth shape or to form a pattern such as a lion head or a raspberry design as with the German roemers. On others the hot glass blobs were pulled out with a tool forming spikes. The texture of these prunts provided a firm grip on the vessel, as diners during the Middle Ages may have been eating with their fingers.
The following pictures show examples from our collection to illustrate various styles of blob decoration.
