So you're getting into glass fusion

Glass fusion is kiln-fired magic: arrange compatible glass pieces, fire them, and they melt into a seamless whole. The barrier to entry is real — you need a kiln — but once you have it, this is one of the most immediately rewarding art forms around. Here's exactly what you need to get started, and what you can skip.

Before you buy anything

A few things worth knowing first

COE compatibility is the single most important concept to understand before buying glass. COE stands for Coefficient of Expansion — how much glass expands when heated. COE 90 and COE 96 are incompatible with each other. Mix them in the same piece and it will crack. Pick one system, buy everything in that system, and don't deviate.

A cheap ceramic kiln from a craft store is not a glass fusing kiln. Glass fusing requires precise ramp-speed control — how fast the temperature rises and falls. A dedicated kiln controller, or a kiln designed for glass work, is non-negotiable. The Skutt Firebox and Paragon kilns made for glass fusion have this built in.

Your first ten projects will be small: coasters, pendants, small tiles. Don't buy a huge kiln — a compact one gives you faster cycle times, lower electricity costs, and teaches you the medium more efficiently. Upgrade when you know exactly what you want to make.

The gear

What you actually need

Kilns

The kiln is the heart of glass fusion — and the first thing beginners overthink. For small-format work (coasters, pendants, tiles, small plates), a compact kiln in the $500–700 range is all you need. The key specs are firing area (8×8″ is plenty to start), a programmable controller (so you can dial in ramp speeds), and 120V operation (no special wiring). When you're ready for larger work, glass-kiln retailers carry mid-size models (14–18") that require 240V.

Kilns — what's the difference?

A few common shapes, each making a different trade.

Compact (8" square)

Perfect for pendants, coasters, tiles. Fires fast, standard outlet.

Best starter
Skutt

Skutt Firebox 8 Kiln With Pyrometer

$$$

The Skutt Firebox 8 is the kiln most glass fusers start on and never outgrow for small work. Programmable controller, fast heat-up, and a proven track record with fusible glass. The 8×8″ chamber handles coasters, pendants, tiles, and small plates — the projects that teach you the medium. Skip cheaper ceramic kilns; they lack the ramp-speed control glass fusing demands.

What we like

  • Built-in programmable controller — set ramp speeds precisely
  • 120V operation, no special wiring needed
  • Skutt is the most trusted brand in hobby kilns

What to know

  • 8" area limits project size — plates wider than 8" won't fit
  • Full firing cycle runs 4–8 hours; plan your schedule around it
See on Amazon →
Budget pick
Paragon

Paragon SC2 Fiber Kiln

$$$

Paragon's SC2 costs a bit less than the Skutt and fires glass well. Fiber construction heats faster and more efficiently than a brick kiln, and the Sentry 3 controller handles precise glass ramp schedules. If you want to spend less upfront and don't mind a slightly smaller round firing area, this is a legitimate entry into kiln-fused glass.

What we like

  • Fiber construction heats faster and costs less to run than brick
  • Paragon has been making kilns for 70+ years — solid reputation
  • Sentry 3 controller handles glass ramp schedules well

What to know

  • Round interior constrains rectangular panel projects
  • Controller interface less intuitive than Skutt's
See on Amazon →

Glass

Not all glass is created equal for fusing. You need fusible glass that's been tested for compatibility — either COE 90 or COE 96. Pick one system and stick with it. COE 96 (formerly System 96) is slightly more available from craft suppliers and works well in most beginner kilns. COE 90 has a long track record in the glass-fusing community. Do not mix systems in the same piece.

Best starter
Oceanside / Wissmach

COE 96 Fusible Glass Assortment — 20 Sheets

$$

This pack bundles sheets from Oceanside, Wissmach, and Spectrum — all COE 96 compatible — giving you 20 sheets of varied colors to work with from day one. Consistent 3mm thickness, guaranteed COE compatibility within the pack, and available without committing to a single brand's catalog. Exactly the variety you need to start designing real pieces.

What we like

  • 20-sheet multi-brand assortment covers your first 10-15 projects
  • All sheets are COE 96 — no compatibility guesswork
  • Standard 3mm thickness works with all common fusing schedules

What to know

  • Smaller range than a full supplier catalog — you'll want more colors soon
  • Doesn't include frit; order a sampler separately for texture work
See on Amazon →
Specialty pick
Delphi Glass

Frit Sampler Pack — COE 96

$$

Frit is crushed glass — coarse, medium, or fine — that you sprinkle onto sheet glass before firing to create texture and shading effects. This COE 96 sampler gives you seven colors across fine and medium grind to experiment with. Essential for adding the depth you can't get from flat sheet glass alone.

What we like

  • Frit adds depth and texture impossible with flat sheet glass alone
  • Seven-color sampler lets you explore before buying full jars

What to know

  • Fine frit is a respirable hazard — always wear a respirator when scooping
  • Mixing COE 90 and 96 frit causes stress fractures; match your system

Budget pick
Oceanside

Oceanside Rainbow Transparents Glass Pack — 96 COE

$

Oceanside's Rainbow Transparents pack gives you a spectrum of COE 96 colors in a single order — perfect for your first few projects without committing to individual 12×24" sheets. Transparent colors let you see how glass changes when light passes through, which is part of what makes fusion results so surprising.

What we like

  • Transparent colors are stunning in finished fused pieces with backlight
  • Single-order variety without buying full 12×24" sheets

What to know

  • Transparent only — you'll want opalescent colors too for contrast
  • Smaller sheet sizes mean more cuts for larger designs
See on Amazon →

Cutting Tools

Glass fusing doesn't require many tools, but the ones it does require matter. A good glass cutter and running pliers let you score and snap clean breaks without wasting glass. A grinder (rotating diamond bit on a water-cooled table) lets you smooth edges and resize pieces precisely. Buy the cutter and pliers first; add the grinder once you know you're hooked.

Best starter
Toyo

Toyo Custom-Grip Supercutter Glass Cutter

$

The Toyo Custom-Grip Supercutter is what glass artists reach for when they stop using disposable cutters — self-oiling carbide wheel, ergonomic grip, and a consistent score every time. Toyo's flagship hand cutter, and the one you won't replace for years. Cuts 3mm fusible glass cleanly on the first stroke.

What we like

  • Self-oiling carbide wheel — no separate oil bottle needed
  • Comfortable pistol grip reduces hand fatigue on longer sessions
  • Professional-grade tool beginners don't outgrow

What to know

  • Costs more than basic cutters — but $8 versions are false economy
  • Needs refilling with cutting oil eventually; takes a few minutes
See on Amazon →
Specialty pick
Silberschnitt

Silberschnitt Glass Running Pliers BO 700.0

$

Running pliers apply even pressure across a score line to produce a clean break without crushing. The Silberschnitt BO 700.0 is a professional-grade German tool that works on straight or gently curved scores, letting you work with shapes that are otherwise very difficult to break cleanly by hand. Under $25 and you'll use them on every project.

What we like

  • Professional-grade tool — clean straight breaks without crushing edges
  • Adjustable jaw depth handles different glass thicknesses

What to know

  • Takes a few sessions to dial in the right jaw pressure
  • Won't substitute for a grinder on tight curves and intricate shapes
See on Amazon →
Upgrade pick
Inland

Inland Wizard IV Glass Grinder

$$$

A glass grinder's rotating diamond bit spins in a water bath, letting you smooth and reshape pieces precisely. Not needed for the first few projects — but once you're cutting tight curves, this is the tool that makes accurate fitting possible. The Wizard IV is Inland's workhorse studio grinder: sturdy, quiet enough for home, and reliably accurate.

What we like

  • Diamond bit grinds wet — no glass dust, smooth edges every time
  • Quiet enough for a home studio or garage workshop
  • Inland has supported the studio-glass hobby for 30+ years

What to know

  • Overkill for your first 5–10 projects; buy after you know you're hooked
  • Requires water and cleanup after every session
See on Amazon →

Kiln Supplies

Every firing needs a few consumables that prevent your glass from welding itself to the kiln shelf. Fiber paper (Thinfire is the brand name everyone uses) goes under every piece, every time. Kiln wash goes on the shelves. These aren't glamorous, but running out mid-project is genuinely miserable — stock up before your first firing.

Best starter
Bullseye

Bullseye Thinfire Shelf Paper — 25 Pack

$

Thinfire is the thin ceramic fiber paper that goes between your glass and the kiln shelf — without it, your fused piece bonds to the shelf permanently. One sheet per firing, cut to size. The 25-sheet pack gets you through your first 25 projects. This is a consumable you'll always need; buy in quantity.

What we like

  • One sheet per firing keeps your glass from fusing to the shelf
  • Burns clean — no residue transferred to your finished piece
  • 25-sheet pack covers your first 25 firings at minimal cost

What to know

  • Single-use; you'll burn through a pack in a few months of regular firing
  • Handle spent paper outdoors — ceramic fibers irritate airways
See on Amazon →
Specialty pick
Primo Primer

Primo Primer Kiln Wash — 1.5 lb

$

Kiln wash is the chalk-like coating you paint onto shelves so glass drips and bubbles don't bond permanently. Primo Primer is the go-to wash for glass fusing — finer texture than general ceramics wash, so it releases cleanly after firing. Apply before your first firing and touch up as it wears.

What we like

  • Fine-particle formula releases glass from kiln shelves cleanly
  • 1.5 lb covers a typical 8" shelf many times over

What to know

  • Must dry fully between coats or it cracks during firing
  • Not the same as ceramics kiln wash — use glass-specific formulas only

Safety

Glass work has two real safety concerns: eye protection when cutting (shards travel fast and far) and respiratory protection when working with frit powder (fine glass dust is a long-term lung hazard). Both are cheap and easy to address. Don't skip them.

Best starter
3M

3M Nassau Safety Glasses — ANSI Z87 with Side Shields

$

Cutting glass sends tiny shards in unpredictable directions. You need side-shielded eye protection — not reading glasses, not sunglasses. 3M's Nassau glasses are ANSI Z87.1-rated, comfortable to wear for hours, and cheap enough to keep two pairs. Wear them every time you cut or break glass, no exceptions.

What we like

  • ANSI Z87.1 rated — certified for impact protection, not just splash
  • Integrated side shields block shards that don't come straight at you
  • Comfortable enough to forget you're wearing them

What to know

  • Not designed for frit dust — add a respirator for powder work
  • Will scratch over time; plan to replace annually
See on Amazon →
Specialty pick
3M

3M 8511 N95 Respirator — 10 Pack

$

Fine glass frit is essentially fine glass dust, and repeated inhalation is a long-term lung hazard. An N95 respirator is all you need when measuring, pouring, or sifting frit. The 3M 8511 has a Cool Flow valve for comfort on longer sessions. One 10-pack lasts most fusers a full year.

What we like

  • N95 filters the fine glass particles in frit and kiln dust
  • Cool Flow valve makes extended sessions comfortable in warm studios

What to know

  • Doesn't address kiln off-gassing fumes — ventilate your space too
  • One-time use; don't re-use a collapsed or saturated mask

Save your money

What you don't need yet

Beginners get pressured to buy a lot of stuff that doesn't help them play better. Here's what we'd skip on day one.

  • Lead came and copper foil tools — That's stained glass — a related but entirely different craft. No kiln, no fusing. Worth exploring later, but not the same thing.
  • A glass torch or blowpipe — Blown glass is a completely different discipline. Glass fusing happens in a kiln, not at a torch.
  • Slumping molds — Slumping (bending flat glass over a mold) is the next step after fusing. Master flat fusing first — then molds make sense.
  • Dichroic glass — Beautiful, expensive, and teaches bad habits early. Master COE compatibility and basic cuts before adding this.
  • Acid etching supplies — An advanced finishing technique. Save it for month six when you're looking to add surface effects to finished pieces.
First week

Your first seven days

A short, real plan to get from gear-on-doorstep to actually playing.

  1. Choose your COE system — COE 90 or COE 96 — before buying a single sheet of glass. Your kiln, glass, and frit all need to match. · Action
  2. Order a starter kiln. The Skutt Firebox 8 is the default choice. · Buy
  3. Order a COE-matched glass assortment and frit sampler. · Buy
  4. Order Thinfire shelf paper, safety glasses, and an N95 mask. You need all three before your first firing. · Buy
  5. Watch two or three firing-schedule tutorials before your first fire. Understanding ramp speed and annealing prevents cracked pieces. · Learn
  6. Design and cut your first three pieces — aim for simple rectangular and square shapes while you learn the cutter. · Action
  7. Run your first full firing cycle. Load your kiln, set the schedule, walk away, and don't peek until it's cooled. · Action
FAQ

Common questions

What's the difference between COE 90 and COE 96?

COE (Coefficient of Expansion) describes how much glass expands when heated. COE 90 and COE 96 expand at different rates and are incompatible in the same firing. Pick one system and buy all your glass — sheets, frit, and stringers — within that system. Most beginners choose COE 96 (formerly System 96) for its wider retail availability.

Can I use a regular ceramics kiln for glass fusion?

Not reliably. Ceramics kilns typically fire much hotter than glass needs, and their controllers often lack the fine ramp-speed control that glass fusing requires. Glass-specific kilns like the Skutt Firebox line are programmed with precise heat curves ceramics kilns can't replicate. Some experienced fusers adapt ceramics kilns with aftermarket controllers, but it's not a beginner path.

How long does a firing take?

A typical full-fuse firing cycle runs 8–12 hours total: a slow ramp up, a hold at full-fuse temperature (around 1480°F), a rapid drop to the annealing range, a slow anneal hold, and a slow cool to room temperature. Don't rush the cooling — glass that cools too fast develops internal stress and can crack days later.

Is glass fusing different from stained glass?

Very different. Stained glass is cold work — you cut, grind, foil or lead-came, and solder, with no kiln involved. Glass fusion involves cutting, arranging, and kiln-firing pieces until they melt together. The cutting and grinding skills overlap, but the glass types, tools, and techniques diverge significantly.

What can I realistically make in the first few months?

Coasters, pendant blanks, small decorative tiles, sun catchers, and small plates are all within reach in the first month. Bowls and larger pieces require slumping molds — a second technique — and come later. Most beginners produce genuinely beautiful small work within their first three to five firings.

How much does each project cost once I have the kiln?

A small project (coaster, pendant) uses a few dollars of glass and one sheet of Thinfire paper. Electricity for a firing adds roughly $1–3 depending on kiln size and local rates. Realistically, most beginners spend $10–25 per project on consumables once the kiln is paid for.
