River Valadez leads six Wednesday sessions on making small hollow forms with borosilicate glass. The class is for students who already have basic flameworking and beadmaking experience.

Miniature bottles, tiny bud vases and straws set the scale for Small Vessels, a six-session UrbanGlass class focused on hollow borosilicate work. Students practice sealing, blowing and shaping at the torch, with heat management and control at the center of the course.
UrbanGlass describes flameworking as shaping glass rods or tubes softened by a torch. In this class, the focus is hollow forms: the listed examples range from miniature bottles and bud vases to straws, and the named techniques include sealing, blowing and shaping.
The course emphasizes heat management and control, not just the finished shape. Those priorities make this a step for students who have already worked with a torch and are ready to apply that experience to hollow glass.

Brooklyn-based ceramicist and glassblower River Valadez works at the torch with borosilicate glass, making tactile, functional vessels. That practice connects directly to the class’s material and small-vessel focus; the listing does not promise a specific finished design for each student.

Each class includes demonstrations followed by time at the torch to practice. Cleanup is part of the three-hour session; UrbanGlass says the final 20 minutes are usually reserved for cleaning workstations. Across six meetings, students get repeated opportunities to work on control and heat management rather than taking a single introductory session.

Demonstrations introduce the techniques, followed by hands-on torch practice. Cleanup is included in each session, with the last 20 minutes usually set aside for workstation cleaning.
Sessions run November 4–December 16, 2026, from 6 to 9 p.m. There is no class November 25.
The class is open to ages 14 and up. Students should have basic flameworking and beadmaking experience and be ready to move beyond solid sculpture; it is not presented as a first flameworking class. UrbanGlass classes are taught in English.

Registration and payment are required, and UrbanGlass accepts electronic payment methods only. The class page does not give a price. Registration is primarily through Eventbrite from the UrbanGlass class page; students can also call the Education Registrar and register by phone with a major credit card. UrbanGlass classes may also appear on CourseHorse; if you register there, UrbanGlass says it will confirm your place and add you as an Eventbrite attendee.
Classes are filled first-come, first-served. UrbanGlass maintains waitlists for full classes and advises students to respond quickly if a place opens. Its general policy accepts sign-ups up to the start of class if space remains, but recommends registering early; a class with low enrollment may be canceled within two weeks of its start date.
Partial scholarships are available for most UrbanGlass classes, but the listing does not confirm one for this class. Ask the Registrar whether one is available. The Registrar can also discuss payment plans.

UrbanGlass provides the basic class materials and supplies, including protective eyewear, which must be worn in the studio. Wear work clothes; flammable or synthetic fabrics, sandals and open-toe shoes are not allowed, and long hair must be tied back. A notebook and water bottle are recommended. Students are responsible for any particular tools or materials they want to use that are not supplied.
The class listing describes the work as primarily seated, involving glass rods and torches. It notes that the studio can be bright and loud, and that handling glass and tools may require dexterity. UrbanGlass says its facility is ADA compliant; the studios are reached through the automatic-door Rockwell Place entrance and an elevator to the third floor. Service animals are welcome, and the organization recommends booties because glass particles may be on the floor.
Flameworking areas are not air-conditioned, and glass work involves heat. UrbanGlass recommends bringing water and monitoring how you feel; the building’s accessibility information also notes fans and filtered-water dispensers. Contact the Education Registrar before class about access needs or accommodations so arrangements can be discussed.

The glass must cool slowly overnight, so students should not expect to take finished work home at the end of class. UrbanGlass says hot-work pieces are available after five business days or when the student is notified; the class listing asks students to return to the studio once notified. Work left uncollected for a month will be recycled.

Cancellations, transfers or changes made more than two weeks before the first class are eligible for a refund. UrbanGlass does not grant refunds for changes or cancellations within 14 days of the start, or for withdrawals after the class begins. Refunds exclude the combined Eventbrite processing and service fees; any donation added to a class purchase is nonrefundable.
Missed sessions cannot be made up outside the scheduled class time. If you expect to miss a session, notify the Registrar. UrbanGlass says classes remain in session while the MTA is running and does not offer refunds or transfers for weather-related absences outside that policy.
