Blown Ribbed Glass Bowls with Delicate Trailing
Blown ribbed bowls (Zarte Rippenschale) with the ribbing ending at an arc under the mouth were decorated with a delicate filament of applied glass trail spiraling around the ribs. This relatively small group of vessels was circulated primarily in northern Italy, the Upper Adriatic, Switzerland and the Rhineland and maybe a Western product, datable to the first century and possibly later. The bowl was made by mold blowing, followed by working free-hand to apply the trailing, expanded by free blowing and finished with working the rim. This type of vessel was also made without the trailing decoration. The examples of both types are shown from many museums and private collections.
