What Third Degree Glass Factory offers
Third Degree Glass Factory is a glass-blowing studio in Philadelphia that teaches people how to make glass art by hand. You work with an instructor in small groups or one-on-one to learn the basics of heating, shaping, and cooling molten glass. The studio provides all the equipment, materials, and safety gear — you show up and learn the craft.
The factory operates as a working studio where artists also create and sell their own pieces. This means you're learning in a real working environment, not a classroom set apart from actual production. Instructors are practicing glass artists who teach while maintaining their own work.
Sessions run on a schedule the studio sets each month. You can take a single introductory class, a series of classes to build skills, or drop-in sessions if you've already completed the basics. The studio also hosts special events and demonstrations.

How to register for a class
Visit the Third Degree Glass Factory website to see the current class schedule. The site lists each class by date, time, instructor, and whether it's for beginners or people with prior experience. You can see which sessions have open spots.
To register, you typically fill out a form on their website with your name, contact information, and which class you want to attend. Some classes may require payment at the time of registration. You should receive a confirmation email with details about what to bring and where to go when you arrive.
If the class you want is full, you can ask to be added to a waitlist. The studio sometimes opens additional sessions if demand is high. You can also call the studio directly if you have questions about which class level is right for you or if you need to reschedule.
What happens during your first session
When you arrive, the instructor will explain safety rules and how the studio works. This includes how to move around the hot glass areas, what protective equipment you must wear, and how to recognize when glass is too hot to touch. Safety briefing typically takes 15 to 20 minutes.
After safety, the instructor demonstrates the basic techniques: how to gather molten glass on a pipe, how to shape it by rotating and blowing, and how to use tools to form details. You watch them do this several times so you see the motion and timing before you try it yourself.
Then you step up to the furnace. The instructor guides your hand as you gather glass, helps you blow and shape it, and talks you through each step. Your first piece usually takes 20 to 40 minutes from start to finish. You'll make at least one piece during a beginner class, sometimes two if time allows.
Materials, equipment, and what you take home
The studio owns all the furnaces, pipes, torches, and hand tools. They provide safety glasses, heat-resistant gloves, and an apron. You wear your own clothes but they must be natural fiber (cotton or linen) because synthetic fabrics melt near hot glass. Closed-toe shoes are required.
The glass itself is included in the class fee. The studio stocks colored glass and clear glass, and the instructor can tell you what colors are available on the day you attend. You don't choose from an unlimited palette, but you have options.
Every piece you make during class is yours to take home. The glass needs to cool slowly after you finish, so the studio places your piece in an annealing oven that cools it over several hours or overnight. You pick it up the next day or a few days later, depending on the studio's schedule. Some classes include pickup in the fee; others charge a small fee to store and return your work.
Class levels and what each teaches
Beginner classes assume you have never blown glass before. You learn to gather glass, shape it by blowing and rotating, use basic hand tools, and finish a straightforward piece. Most beginner classes focus on making a small vase, ornament, or drinking glass. You leave with a finished object and an understanding of how the craft works.
Intermediate classes are for people who have completed at least one beginner class or have prior glass-blowing experience. These sessions teach more complex shaping, color techniques, and how to make larger or more detailed pieces. You might learn how to layer colors, create patterns, or work with thicker glass.
Advanced classes and open studio time are for people with significant experience. Open studio sessions let you work independently while an instructor is present to answer questions and help with difficult techniques. These are not taught classes but supervised work time.
Cost and how to pay
Beginner class fees vary depending on whether you take a single session or a series. A one-time introductory class typically costs between $75 and $150, though prices change and depend on class length and group size. A series of four or six classes costs more per session than a single class but less overall.
Private one-on-one instruction costs more than group classes. The studio may offer discounts for multiple classes booked at once or for returning students, but you should check their current pricing page for exact amounts.
Payment methods usually include credit card, debit card, and sometimes cash or check, depending on how you register. If you register online, you typically pay at that time. If you call to register, the studio will tell you when and how to pay.
What to know before you book
Glass blowing involves heat, so it is physically demanding. You stand near a furnace that reaches over 2,000 degrees Fahrenheit, and you hold a pipe with hot glass on the end. If you have back problems, joint issues, or heat sensitivity, tell the instructor before class starts so they can help you work safely or suggest modifications.
The studio is loud because of the furnaces and equipment. If you are sensitive to noise, expect a high-decibel environment. Hearing protection is usually available if you ask.
Class sizes are small — usually four to eight people in a group class — so you get individual attention. However, this also means you may wait for your turn at the furnace while other students work. A typical two-hour class might give you 30 to 45 minutes of hands-on time at the glass.
The studio's schedule changes seasonally. Summer classes may run more frequently, and winter may have fewer options. Check their website for the current month's offerings rather than assuming the same classes run year-round.
Frequently Asked Questions
Do I need any experience to take a beginner class?
No. Beginner classes are designed for people who have never blown glass. The instructor teaches you everything from the safety rules to how to gather and shape your first piece. You should be in reasonable physical health because you'll stand and hold equipment, but prior craft experience is not required.
What if I'm left-handed?
Tell the instructor when you arrive. Glass-blowing techniques can be adapted for left-handed people, though some tools and the furnace setup are designed with right-handed use in mind. The instructor will show you how to position yourself and your pipe so you can work comfortably.
Can I bring a friend or family member to watch?
Most studios allow observers in the space, but you should ask when you register. There may be safety restrictions on where spectators can stand, and some classes may not allow visitors due to space or insurance limits. Call ahead to confirm the studio's policy.
What if I want to make a specific item, like a drinking glass or a vase?
Tell the instructor what you'd like to make when you arrive or when you register. Beginner classes teach basic techniques that work for straightforward shapes like vases, ornaments, and small bowls. More complex items like drinking glasses with handles or detailed sculptures require intermediate or advanced skills and may not be possible in a first class.
How long does it take to become good at glass blowing?
You can make a recognizable piece in your first class. Building real skill — making consistent shapes, working with color, creating larger pieces — typically takes 10 to 20 hours of practice spread over several weeks or months. Many people take a series of classes to build confidence and technique before deciding whether to pursue it further.
