Bandhu Dunham's Beginner Goblets

Runtime: 55 minutes
Skill level: Early Learner – Intermediate
Requirements: Your own torch or access to one
 
We are delighted to present internationally renowned borosilicate artist, educator, and author Bandhu Scott Dunham (USA) in this comprehensive E-demo exploring the fundamentals of hollow-form construction through the making of an elegant petroglyphic goblet.
 
Designed for early learner to intermediate lampworkers, this demonstration provides an accessible introduction to goblet making while developing the core technical skills that underpin blown vessels, scientific glass, and many sculptural hollow forms.
 
Throughout the demonstration, Bandhu guides viewers through every stage of constructing a decorative borosilicate goblet—from pulling accurate points and preparing counterweighted punties to blowing the bowl, creating a symmetrical foot, and assembling the finished piece. While the goblet itself is the final object, the techniques demonstrated translate across countless hollow-form applications.
 
What you'll learn
Pulling and centring accurate points
Creating controlled bubbles with even wall thickness
Heat management during hollow-form construction
Working confidently with heavy-wall borosilicate tubing
Decorative stringer application and petroglyph-inspired surface design
Goblet assembly, proportion and finishing techniques
 
Bandhu demonstrates how careful preparation at every stage influences the final outcome, showing how symmetry begins long before the glass is blown. Students learn practical strategies for maintaining even heat, controlling wall thickness, preparing balanced punties, and developing consistent proportions throughout the construction process.
 
The demonstration also explores many of the subtle principles that experienced glassmakers rely upon, including:
Why thinner-wall tubing often produces more predictable blown forms
Building heat gradually before inflation
Blowing in stages to maintain wall thickness
Using counterweighted punties for improved control
Creating elegant proportions through thoughtful bowl, stem and foot relationships
Understanding how sequencing and preparation improve efficiency and consistency
 
Throughout the demo, Bandhu continually reinforces that successful hollow-form construction depends upon observation, patience and thoughtful decision-making rather than speed. Students are encouraged to slow down, evaluate their work at every stage, and understand why each operation is performed in its particular order.
 
This E-demo can be completed entirely at your own pace. The techniques are suitable for ambitious beginners through to intermediate lampworkers wishing to strengthen their hollow-form skills, and provide an excellent foundation for more advanced vessel making.
