Operated by Glass Class Denver · Englewood, Colorado
Englewood, Colorado sits just south of Denver, and here a studio-classroom hums with torchwork and molten color: the ZWICK Two Day Class offers focused, hands-on marble making led by Thomas Zwick. Over two intensive days (weekend sessions run 10 a.m. to 6 p.m.), students move from flower compressions to stringer layering, sleeving clear tubing, and learning rounding techniques while watching live demos and practicing at designated torch stations.
The format is practical: mornings begin with a demonstration tailored to the day's curriculum, then participants rotate through torch time and observation spots. Lunch is provided both days, and the instructor encourages students to steer part of the lesson with requests and questions, creating a responsive classroom dynamic. Techniques covered range from color theory to advanced compression styles, so the class suits beginners who want a structured introduction and intermediate artists seeking to refine marble-specific skills.
What sets ZWICK apart is Thomas Zwick himself — an artist who pivoted to glass in 2013 after a formative exhibition and who carries a decade of workshop experience from notable teachers across the U.S. That lineage shows in the balance of technical rigor and creative freedom: the studio emphasizes safe torch practice, efficient workflow, and thoughtful color choices while making space for playful experimentation. The studio is also an integral creative node in the Englewood arts scene, drawing makers from Denver and surrounding towns and contributing to the city’s growing maker-community reputation.
Physically the class demands steady hands more than brute fitness. Expect to stand, lean into the torch, and manage short bursts of focused concentration. Safety gear and ventilation are standard; students learn protocols before handling molten glass. Materials are provided in-class unless otherwise noted; check with the organizer for take-home kiln schedules or shipping of finished pieces.
For travelers staying in nearby Denver or Englewood, this two-day intensive doubles as a creative micro-residency: pack a small notebook, a camera for demo shots, and comfortable closed-toe shoes. Whether you’re chasing a new studio skill, building a portfolio of handmade marbles, or simply curious about the chemistry of flame and color, the ZWICK Two Day Class promises a concentrated, memorable plunge into contemporary marble making.
Exact meeting point and studio address are provided after booking. Minimum age is 13. No prior torch experience required, though students with some lampworking exposure will gain immediate momentum.
Zwick’s curriculum is rooted in a lineage of lampworking mentors — from early workshops with Banjo, Joe Peters, Elbo and Tyson Peltzer to later study with John Kobuki, Robert Mickelsen, Coyle Condenser and Brian Jacobson — which shapes a curriculum that’s both technical and inventive. Students leave with finished work and practical habits for studio safety, color mixing, and torch setups that accelerate practice.
No — the class is built for beginners through intermediate students; safety and basic torch protocol are taught before hands-on time.
