Calendar Next session starts Jan 23, 2026 at 9:30 am, runs for 8 weeks

Let's light it up! In this class, you'll explore stacking readymade glass and using kiln-fired enamel as a solder to create your own plasma light sculpture. If you are new to glass, create your sculpture with found glass vessels like vases, bottles, cups, and bowls. If you have experience in glass making, bring your own handmade cups or vessels and explore turning them into plasma sculptures. This class will utilize the equipment in the cold shop to cut, drill, and grind your ready-made glass; harness the power of the kilns to fire your work; and use the plasma cart to fill the vessels with gas. No experience needed.

 

Please bring 4 - 6 sets of glasses or vessels to work with. This class is designed for 2 projects to be filled with plasma.

 

Class does not meet on 3/6.

This five-day class is an introduction to the emerging artistic medium known as plasma light art. We will combine the fundamentals of physics and furnace glassblowing to create illuminated glass sculptures – the proverbial lightning in a bottle!

There is something magical about this process of making light. By producing light through the use of electrified gases, we create an invitation for play as it responds to your proximity and touch. If you think this is neon, you will be surprised how different this will be. Plasma light art is an evolving and experimental art form. If this sounds interesting, then I invite you to come join us.

We will cover the fundamentals for creating a vacuum tight vessel using various hot glass techniques and shaping methods. We will also discuss guidelines on form and structure, design considerations, and preparing your sculptures to be filled.

Our class time will start with demonstration, practice exercises, lecture/discussion and offer as much work time as possible. When you include having to fill our sculptures with gas, we will need all the time the class has to offer! Expect to make use of open studio time.

A list of easy to digest resources is available to prepare yourself at “Plasma Primer: Learning Resource for Students, Co-learners, and Educators” on taminglightning.net

Hot glassblowing has always been a collaborative art making process. This class requires some basic hot glass skills and an open mind prone to misdirection. So it’s important that you are comfortable working in the hot shop and working with a partner. This means you have a working knowledge of glassblowing fundamentals, while you may need some guidance here or there, and the ability to work through independent ideas with coaching and demonstration.

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.

Lightning in a Bottle: Plasma Filled Borosilicate

$950 MEMBER PRICE: $950

with Angela McHale

Calendar Next available session starts Jul 27, 2026 at 9 am, runs for 1 week

In this intermediate five-day class, you will learn the fundamentals of hollow sculpting borosilicate glass at the torch in order to design plasma lighting. We will cover shaping, texture, and creating proper seals to make simple and complex sculptures. Sculpting techniques will cover abstract and figurative forms. You will also learn to add and design around the electrode and filling tube.

We will cover advanced topics like encasements and inclusions of phosphor as well as problems and design challenges presented by this method of working. Once your glass vessel is complete and checked for leaks, we will put our pieces under vacuum and fill them with noble gasses!

Class time will alternate between demonstration, discussion, and plenty of work time. You are strongly encouraged but not required to use the evening open studio.

On the last day we will light up all of our work and have our own plasma show.

Come to class with a sketchbook and plenty of ideas. Reference photos are encouraged for students with specific ideas they’d like to pursue.

Experience working with hollow borosilicate glass is required, however experience with plasma/neon is not. Students should at least be comfortable connecting hollow tubes to make a "straight seal."

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.

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.
