Han Duong’s beginner-friendly class takes students from sizing a glass ring to adding torch-shaped details. The work cools at the studio, so plan to return for pickup.

In this UrbanGlass class, the ring comes first as a fit problem: participants learn to size borosilicate glass for a finger, then decorate the cooled shape. Han Duong demonstrates before students practice flameworking, a torch-based process that turns glass rods soft enough to shape.
The class works with prepared borosilicate rods at a torch. Once students have sized and cooled a ring, they practice pulling stringers—thin glass strands—and attaching small bits as embellishments. The order matters: participants work on the ring’s fit before moving to its decoration.
UrbanGlass defines flameworking as shaping pre-made rods or tubes after torch heat softens them. Borosilicate is used in this class because it withstands thermal shock, or sudden temperature changes. This is torch work on softened glass, rather than coldworking, which shapes or decorates glass at room temperature.

Duong’s demonstration is followed by hands-on practice. UrbanGlass describes learning to control heat and gravity as part of the work, so the class is geared toward trying the process as well as making wearable forms. No prior experience is required, although the listing says experience may help.

Han Duong leads the class through a demonstration and practice with glass rods and torches. The project connects two distinct decisions—sizing a ring to fit, then adding stringers and attached glass details—within a single introduction to borosilicate work.

Intro to Boro: Rings and Things! (November) | UrbanGlass ↗ · Registration Info | UrbanGlass ↗
The class listing says students should be able to leave with two to three rings. Its preparation guidance gives a more cautious expectation: one or two successful pieces, alongside experimental attempts. The number of finished rings may vary as participants practice.
UrbanGlass recommends registering early because enrollment informs materials and teacher planning, and a class with low enrollment may be canceled within two weeks of its start date. Classes are filled first come, first served; waitlists are kept when a class is full. Sign-ups are accepted up to the start of class, subject to availability.
Registration is primarily through the Eventbrite widget on the class listing. Phone registration is available Tuesday through Saturday, 10:30 a.m.–6:30 p.m., at 718-625-3685, ext. 246. UrbanGlass currently accepts electronic payment methods.

UrbanGlass provides the basic materials and supplies needed for class. A notebook and water bottle are recommended; students who want to use specific tools or materials not supplied must obtain them themselves.
Protective eyewear is required throughout the studio, and UrbanGlass provides suitable eyewear. Wear appropriate work clothes: flammable or synthetic fabrics, sandals, and open-toe shoes are not allowed. Long hair must be tied back.
Student cancellations, transfers, or other changes made more than two weeks before the first class date are eligible for a refund. Changes within 14 days of that date, or withdrawals during class, are not refundable; Eventbrite payment-processing and service fees are excluded from refunds.
UrbanGlass says classes remain in session as long as the MTA is running. It does not offer refunds or transfers for weather-related absences outside that policy. Missed classes cannot be made up.
Flameworking is primarily seated, but the environment can be bright and loud, and handling glass and tools may require dexterity. UrbanGlass advises that its flame shop can be hot; working areas do not have air conditioning. Bring water and monitor how you feel.
