Malcolm Kriegel leads this one-session Brooklyn workshop on Nov. 22, 2026. The drills focus on glassblowing technique, not making a finished piece to take home.

In glassblowing, a gather is molten glass collected on a blowpipe before it is inflated and shaped. UrbanGlass’s bootcamp narrows the work to getting consistent gathers and practicing punties—a focused day of repeating particular techniques rather than moving among different glass processes.
UrbanGlass defines a gather, also called a gob, as molten glass on the end of a blowpipe; the glassblower inflates and shapes it toward a desired form. The class’s emphasis on drawing clean, consistent gathers puts attention on that early stage of the work.
The other stated target is practicing punties. The class listing describes drills for both techniques, but does not set out a sequence of separate projects.

Instructor Malcolm Kriegel is a Brooklyn-born artist whose early training included wood, metal and fiber at Fiorello H. LaGuardia High School for Music & Art and the Performing Arts. He later studied glass at Tulane University’s Newcomb Art Department, earning a BFA in 2018.
His UrbanGlass biography says he went on to incorporate glass into mixed-media sculpture about creating and navigating interpersonal relationships. That background describes his artistic practice; the workshop listing identifies drills, rather than those sculptural themes, as the lesson’s focus.

The class listing describes the hot shop as loud and potentially very warm; the glass is listed at about 2,000 degrees. Glassblowing involves sitting, standing and handling hot glass. Working with glass and tools may require dexterity and the ability to lift approximately 5–10 pounds.
UrbanGlass says its working areas do not have air conditioning. The studios have fans and filtered-water dispensers; the organization recommends bringing water and monitoring how you feel in the heat.
