Wineglass with A Penne
A penne is a decorative technique that originated in antiquity. It was used by the Romans and, beginning in the 16th century, by the Venetians. Here, the technique is demonstrated using a wrap and a fin mold.
A thick tube of clear glass has been made, and a small amount of opaque white glass is trailed on to form a spiral wrap. After reheating, the glass is plunged into a special mold, creating the combing effect. After the mold, the glass is pulled on the marver to create the extreme festoons we see. The glass is pulled and twisted as blowing takes place, and from here glassblowing can begin for creating the object.
