This intensive, week-long master class immerses participants in the material culture and making techniques of European medieval glass, with a particular focus on Germanic traditions. Through close study of historical drinking vessels from the Middle Ages, participants will investigate form, proportion, and construction, and actively translate these historical methods into rigorous contemporary hot-shop practice.
The class concentrates on the production of glasses, beakers, and goblets, drawing directly from Römer and Nuppenbecher traditions. Participants learn and apply techniques including prunting, trailing, stamping, and patterned surface work, adapting these processes across a range of forms and scales.
Emphasis is placed on precision, control, and an understanding of historical methods—not replication for its own sake. Techniques developed throughout the week support the creation of original sculptural work informed by medieval processes.
This is an advanced, hands-on course with extensive individual feedback. A minimum of one year of glassblowing experience is required.

DAY 1: The fundamentals: overview of the history of medieval glass objects and glass blowing focusing on the works from the Middle Ages. Hotshop demonstration. Discussion of theory and properties of glass and how to manipulate it. Practice of the trail techniques.
DAY 2: Elements & theory: discussion of techniques and demonstration with focus on the importance of angles and proportion and how to achieve them. Learn how to make and manipulate different shapes. Practice of the prunt technique and how many prunts one can apply to a vessel.
DAY 3: Techniques & shapes: to create more advanced pieces, learn extensive methods to transform the shape of glass. Concentrating on using stamps and blown prunts.
DAY 4: Advancing theory & principles: Go deeper into theory and principles of applying prunts, trails, stamps and patterns. Start to create a shape and a piece with two blown parts.
DAY 5: Pushing boundaries & refining blown shapes: Practice of techniques and experimentation with prunts, trails, stamps and patterns.
DAY 6: Your Own Design: using the techniques learned throughout the week, build your own design inspired by the past.
