Incredibly Intricate Murrine

$950 MEMBER PRICE: $950

with Penelope (Rakov) Lee

Calendar Next available session starts May 18, 2026 at 9 am, runs for 1 week

In this five-day class our goal is to break down the best method for constructing incredibly intricate murrine. Because of its complexity, murrine can be intimidating and hard to know which steps to do in what order. But by slowing down and really looking at how to best approach each step in the process, we can achieve the kinds of patterns that can seem impossible.

We will cover:

  • Some color theory
  • How to pull successful cane
  • How to build simple, and then complex bundles
  • When to work hot, and when to work cold
  • What to look for when cutting murrine for the hot shop, the kiln shop, and other applications
  • How to set up a plate for patterned roll ups
  • And finally, how to manage your piece with all those murrine.

Talk Suppio

$950 MEMBER PRICE: $950

with DJ Benyosef

Calendar Next available session starts May 25, 2026 at 9 am, runs for 1 week

This five-day glassblowing class will focus on pulling cane to create cane tubes, known as "suppios." This technique is excellent for producing matching or similar objects, making it ideal for production-style work. You will learn the entire process, from pulling cane and rolling it onto a bubble to pulling the tube and cutting it into smaller tubes or cups (suppios). We will also cover gathering, twisting, and blowing up the tubes.

By the end of the course, students will have a deeper understanding of pulling even cane, managing wall thicknesses, and achieving uniform twists. The class will also introduce various wraps and incalmo techniques.

Historical Objects, Contemporary Methods

$950 MEMBER PRICE: $950

with Ryan Tanner

Calendar Next available session starts Jun 1, 2026 at 9 am, runs for 1 week

In this cross-disciplinary class, you will use the torch to create objects out of glass that will then be engraved by handheld diamond tools. Inspired by the origins of engraving, we will investigate how to recreate some of the first known works carved by humanity. As we make our own versions of these objects, we will experiment with how to combine these techniques and processes into our individual artistic practices.

Students will start by developing a basic knowledge of torchworking in the Flame Shop to create their own cabochon and cylinder seal shapes. Once these objects are made, we will take them to the cold shop, where you will learn the art of engraving with handheld diamond drills. We will also introduce other various coldworking techniques such as lapidary grinding and sandblasting to shape and assemble our projects.

Through the study of ancient glassmaking and engraving, you will explore different ways to adapt to the changes in materials and technologies from history to the present. As a team of researchers, we will learn to remake these objects in a contemporary, but still true-to-process method.

All levels are welcome from beginners to intermediate students.

Non-Traditional Pâte de Verre

$950 MEMBER PRICE: $950

with Evelyn Gottschall Baker

Calendar Next available session starts Jun 8, 2026 at 9 am, runs for 1 week

One of the greatest challenges in kilnformed glass is capturing intricate detail in finished work. This hands-on five-day class introduces students to non-traditional Pâte de Verre techniques—an innovative approach to working with glass paste at low temperatures without the use of investment molds. You will learn how to recreate real or imagined objects in striking detail, while also exploring methods that lend themselves to expressive abstraction.

Through demonstrations, discussion, and guided practice, you will explore:

  • Silicone Molds – Make replicas of small objects using two types of silicone molds: one with common household caulking, and another with two-part pourable silicone rubber.
  • Freeform Sculpting – Shape glass paste directly using simple tools such as palette knives, creating unique forms without molds.Color Samples – Create and test color swatches, learning how low-fire schedules affect color maturity and how to achieve desired visual outcomes.
  • Exploring Binders – Experiment with three different binders, comparing their strengths and weaknesses for various applications.
  • Dry Working – Develop methods for refining detail, smoothing surfaces, and preparing pieces for successful firing.
  • Cold Working – Develop methods for cleaning and refining surfaces after firing.
  • Technical Discussions – Gain insight into low-fire kilnforming challenges, including managing shrinkage, balancing thin and thick areas, fusing schedules, and kiln support strategies.

By the end of the course, students will have a toolkit of practical techniques for shaping glass paste into forms rich with texture, depth, and detail—equally suited for realism or abstraction.

Advanced beginners are welcome, however they must have some understanding of firing schedules and heat work in a kiln.

Reflections in Glass: Mirroring the Sculpted Bubble

$950 MEMBER PRICE: $950

with MiNHi England

Calendar Next available session starts Jun 15, 2026 at 9 am, runs for 1 week

This intermediate-level class invites you to explore the reflective possibilities of glass through the process of creating chemically mirrored blown sculptures. Students should already be proficient in gathering and blowing a bubble, as the class will build on those core skills to develop refined, sculpted forms suited for silvering techniques.

The first three days will be spent in the hot shop, focusing on the intentional setup of a bubble designed for mirroring. You will learn how wall thickness, form, internal access, and glass cleanliness each influence the success of the silvering process. The class will experiment with transparent color applications in bar and frit, observing how different hues interact in front of a mirrored surface to create variations in tone and depth within the final chrome finish.

Through daily demonstrations and guided practice, we’ll cover foundational sculpting techniques including bitwork, simple bubble manipulation, and torch-worked surface texturing to enhance form and optical complexity.

The final two days will transition to the classroom, where you will learn the pouring chemical mirroring process. Special attention will be given to the chemistry and care of mirrored surfaces, how to achieve a clean, even silver coat, and the best methods for sealing and maintaining its brilliance over time.

By the end of the course, you will leave with a deeper understanding of how to merge hot shop form making with reflective surface treatment, creating mirrored glass objects that are visually dynamic and built to last.

Additional Class Materials

Organic vapor respirator is required for the mirroring process. Students may bring their own. Respirators can be purchased from PGC prior to the class for $80.

Evening Open Studio

Studios are open until 9:30PM for students to practice. Depending on the class, process, and techniques, this time might be highly suggested by instructors for students to use. In other classes, this time might be considered optional.

Calendar Next available session starts Jun 15, 2026 at 9 am, runs for 1 week

Beads have served as vessels of history, trade, and personal expression—and in this five-day class, they become a laboratory for flameworking exploration.

Using the bead as our central object of study, you will progress from mandrel-wound soda lime beads to hollow, off-mandrel, and blown sculptural beads in both soft glass and borosilicate. Along the way, we’ll cover color use, surface pattern and treatment, hollow-form techniques, and strategies for efficient production.

Grounded in almost 30 years of professional glasswork, the instruction combines deep technical knowledge with inventive problem solving. Expect a fast-paced but relaxed environment, filled with demonstrations, hands-on practice, and plenty of tips and tricks that you won’t find in books.

The focus is on pushing technical skills, broadening your design vocabulary, and helping you refine or reinvent your own beadmaking practice. You’ll leave with a collection of beads—ranging from small studies to oversized sculptural objects—that can stand on their own or be integrated into jewelry, strands, or other creative projects.

Expect to make a lot of beads, gain new skills, and walk away with fresh inspiration for your work.

This class is ideal for intermediate to advanced flameworkers, though adventurous beginners are welcome.

Additional Class Materials

A blow hose assembly kit is required. Students may bring their own or kits are available for purchase on-site on the first day of class for $40.
