A Compact Vitrigraph Kiln for Pulling Stringers

The Jen-Ken AF3P Vitri Barrel is a specialty kiln designed for one specific glass technique: vitrigraph stringer pulling. Unlike a standard glass kiln that holds glass inside, the Vitri Barrel has a hole in the bottom that lets molten glass flow out so the artist can pull it into stringers, rods, ribbons, and decorative glass elements as it falls. It's how studio glass artists make their own custom stringers in any color or pattern they want.

Inside, you've got an 11" x 9" chamber with 0.55 cubic feet of capacity. The kiln is side firing only, with the elements on the chamber walls to bring the glass to working temperature without heating the bottom (where the glass is flowing out). It fires up to 2150°F, but the glass starts flowing out the bottom hole around 1650°F. The kiln plugs into a standard 120V wall outlet (NEMA 5-15) and weighs only 50 lbs, so it's portable enough to set up in any working glass studio.

The kiln comes as a three piece stacked design by default. If you prefer, you can special order it with the pieces attached and a hinged lid.

Important: this is a specialty kiln, not a beginner kiln

Vitrigraph stringer pulling involves molten glass flowing out the bottom of the kiln at around 1650°F. This is genuinely dangerous if you don't know what you're doing. Please seek proper instruction from a qualified instructor or workshop before attempting to fire this kiln and pull stringer. If you're new to glass and just want to fuse or slump, this is not the right kiln for you. Take a look at our ProFusion or AF3P glass kilns instead.

Setup: must be fired on a steel rack, not on a table

This kiln must be fired on a steel rack with a large steel container positioned below to catch the hot glass as it flows out. Do not fire this kiln on a table or any surface that can't safely contain molten glass. Proper protective gear is required: high temperature gloves, appropriate clothing, eye protection, and the right tools for pulling stringer. Set up in an appropriate area with adequate ventilation and fire safety precautions.

Convertible to fusing or ceramics

With the optional second solid floor (no hole), the Vitri Barrel can be converted into a standard fusing or small ceramic kiln. So if you want a kiln that does vitrigraph work plus everyday glass or small ceramic firings, the solid floor accessory gives you that flexibility.

Included with every order

The Orton Digital AF3P 3 Key controller, base brick (or optional stand), 2 year limited warranty through Jen-Ken, and free shipping to the US Lower 48.

Who Is This Kiln For?

The Vitri Barrel is built for a specific kind of glass artist. Here's how to tell if that's you.

✓ Fused glass artists making their own stringers

If you've been buying commercial stringers and want to make your own in custom colors, patterns, and twists, this is the kiln that lets you do it.

✓ Studio glass artists exploring vitrigraph technique

Pull rods, ribbons, decorative drips, and unique glass elements that other artists can't replicate. A specialty kiln for a specialty technique.

✓ Glass instructors and workshop programs

If you teach vitrigraph technique or want to add it to your workshop offerings, this is a portable, accessible, classroom friendly setup.

✓ Working glass studios adding stringer capability

If you already have a main fusing kiln and want to add vitrigraph as a complementary technique, the 120V plug and small footprint make it easy to add without major studio changes.

The Vitri Barrel ships with the Orton AutoFire 3 Key controller, which is the no frills option that handles vitrigraph firing schedules well since you're typically running the same heat to flow profile each session. If you want more programming flexibility (especially if you're converting the kiln with a solid floor for other glass work), upgrade at checkout to the AutoFire 12 Key or TAP Smart Controller.

FAQ - KILNS

What to consider when buying a Kiln

1. What are you firing?
Different materials have different temperature requirements. Pottery and stoneware need to reach cone 6–10 (around 2200–2350°F), while glass fusing works at lower temperatures but demands very precise, programmable cooling. Knowing your primary material upfront narrows your options significantly.

2. How much volume do you need?
Think about how many pieces you fire per week. Hobbyists and home studios generally do well with kilns under 5 cubic feet. Working artists typically need 5–10 cubic feet, and classroom or production studios often require 10+. A good rule of thumb: buy slightly larger than you think you need — you can always fire a half-full kiln, but you can't fire a piece that doesn't fit.

3. Check your electrical setup before you buy
Most mid-to-large kilns require a 240V dedicated circuit, which may need to be installed by a licensed electrician. Smaller kilns may run on standard 120V. Always check the kiln's amperage requirements against your existing panel before purchasing — electrical upgrades can add $200–$500 to your setup cost.

4. Manual vs. digital controller
Manual kilns use switches you adjust by hand throughout the firing, requiring you to stay close. Digital controllers let you program a firing schedule and walk away. For most potters today, a digital controller is worth the extra cost — the results are more consistent and the convenience is hard to give up once you've had one.

5. Don't forget ventilation
Kilns release fumes from clay, glazes, and organic materials during firing. A downdraft vent system is strongly recommended for any indoor studio. It protects your health, improves firing results, and extends the life of your elements. Budget around $150–$300 for a quality vent, and factor it into your total setup cost from the start.

6. Think about long-term running costs
The purchase price is just the beginning. Heating elements need replacing every 100–200 firings ($100–$300 depending on kiln size). Electricity costs $2–$8 per firing depending on your kiln size and local rates. You'll also need kiln furniture — shelves, posts, and stilts — which are typically sold separately and are essential from day one.

What size kiln do I need for my studio?

The right size depends on how much you fire and how often. Hobby potters or small home studios generally do well with a compact kiln (under 5 cubic feet), while working artists and classroom studios benefit from a larger kiln like the Olympic Champ XL. Consider how many pieces you fire per week — if you're constantly waiting to fill a small kiln, it's time to size up. It's usually better to buy slightly larger than you think you need.

What's the difference between a top-loading and front-loading kiln

Top-loading kilns are the most common for pottery and ceramics. They're more energy-efficient, easier to load evenly, and generally more affordable. Front-loading kilns (also called car kilns or door kilns) are better suited for large sculptural work or production studios where loading heavy pieces at waist height is more practical. For most potters, a top-loader like the Champ XL is the right choice.

What electrical requirements does this kiln need?

Electrical requirements vary by kiln model and size. Many mid-size and larger kilns require a dedicated 240V circuit, while some smaller models may operate on 120V. It is important to check the kiln’s specifications for the correct voltage, amperage, outlet type, and breaker requirements before installation. A qualified electrician should handle installation if a new circuit or outlet is needed. Never use a kiln with an outlet or circuit that does not match the manufacturer’s requirements.

Can I fire both pottery and glass in the same kiln?

Yes, in some cases — but it depends on the kiln and how you plan to use it. Many electric kilns can be used for both pottery and glass, but the firing schedules for each are very different. Glass typically requires slower, more precise heating and cooling cycles to help prevent cracking, while pottery firing follows different temperature and timing needs. If you plan to fire both, a kiln with a programmable controller is especially helpful for managing and switching between firing programs. Always check the kiln manufacturer’s recommendations before using it for multiple materials.

What cone temperatures can this kiln reach?

The cone temperature a kiln can reach depends on the specific model. Many ceramic kilns are designed to fire anywhere from low-fire ranges like cone 06–04 up through mid-fire and, in some cases, high-fire ranges such as cone 8–10. Always check the kiln’s product specifications to confirm its maximum cone rating and make sure your clay and glaze are compatible with that firing range.

Do I need a kiln vent, and is one included?

A kiln vent is strongly recommended, though it may not be included with your kiln purchase. During firing, kilns release fumes from clay, glazes, and organic materials — these can be harmful in an enclosed space. A downdraft vent system pulls air through the kiln and exhausts it outside, protecting both you and your work. Even if your studio has good airflow, a dedicated vent improves firing results and extends the life of your elements and lid.
