Eric Goldschmidt 3: Burgundy Goblet

Runtime: 50 minutes
Skill level: Advanced
Requirements: Your own torch or access to one
 
We are pleased to present Eric Goldschmidt, Properties of Glass Programs Supervisor at The Corning Museum of Glass, in this in-depth E-demo focused on advanced borosilicate blowing, precision goblet construction, and refined control of form.
 
This E-demo is designed for intermediate to advanced lampworkers interested in hollow work, scientific glass techniques, and developing greater precision when constructing elegant functional forms. The class centres on the making of a Burgundy goblet, combining technical discipline with aesthetic balance and structural clarity.
 
In this demonstration, Eric guides viewers through the complete process of building a blown goblet form, exploring how heat placement, airflow, and controlled rotation work together to achieve proportion, symmetry, and clean transitions between bowl, stem, and foot. While the final object is specific, the skills demonstrated translate directly into broader blown and hollow-form practice.
 
What you will learn
Managing heat and airflow when working with larger blown forms
Controlling wall thickness and maintaining symmetry
Building clean transitions between bowl, stem, and foot
Using rotation speed and timing to refine form
Developing stability and balance in functional glass design
 
Eric demonstrates practical approaches to shaping and adjusting the goblet as it develops, showing how small refinements in heat and movement influence the final result. Viewers will learn how to read the glass, maintain structural integrity, and make subtle corrections while preserving elegance and clarity in the finished piece.
 
Throughout the process, Eric emphasizes patience, observation, and disciplined execution. The demo reflects the realities of advanced blowing work, including constant evaluation, incremental adjustments, and the importance of confident decision making at the torch.
 
This E-demo can be completed entirely at your own pace. Techniques shown are advanced and require patience — expect challenges, corrections, and learning moments as part of the process.
After purchase, access may take up to 24 hours to activate.
