How Much Does It Cost to Fire Pottery?

Firing pottery at a studio typically costs $5 to $25 per piece, or roughly $0.04 to $0.06 per cubic inch, depending on how the studio bills. If you own your kiln, electricity alone runs $5 to $20 per firing, though total ownership costs (maintenance, elements, replacement parts) push the real per-firing cost somewhat higher.

This guide breaks down both pricing models — studio firing fees and self-owned kiln costs — so you can estimate your firing budget either way.

Quick Cost Overview

Firing Method Typical Cost Billed By Studio, per-piece pricing $5–$25 per piece Size or weight Studio, per-cubic-inch pricing $0.04–$0.06 per cubic inch Volume Studio, per-shelf/kiln-share $15–$63 per cubic foot Shelf or cubic foot Own kiln — electricity only $5–$20 per firing kWh used Own kiln — all-in (electricity + maintenance) Under $30/month with regular use Ongoing

Which option is cheaper depends almost entirely on how often you fire. Occasional firers save money at a studio; frequent firers save money owning a kiln.

How Studios Calculate Firing Fees

There’s no single industry standard — studios use one of several methods, and it’s worth understanding each before you commit to a studio.

By Cubic Inch (Most Common)

Charging by volume has become the standard approach for many studios, since kiln space is limited and larger pieces reasonably cost more to fire. A typical rate for combined bisque and glaze firing using studio glazes runs around $0.06 per cubic inch, which factors in electricity, kiln maintenance, glaze costs, and labor to load and unload the kiln.

Example: a mug measuring 4 × 3 × 5 inches works out to 60 cubic inches, which at $0.06/cubic inch comes to $3.60 for both bisque and glaze firing.

Some studios separate the two firing stages: bisque alone might run around $0.04 per cubic inch, with glaze firing priced separately on top.

By Weight

Some studios simplify billing by weighing the piece and charging per pound instead of measuring volume, often in the $1–$5 per pound range depending on the studio. This is easier to administer, though it can undercharge for large, lightweight pieces that take up more kiln space than their weight suggests.

By Shelf, Kiln-Share, or Cubic Foot

Some studios skip per-piece billing entirely. A flat rate for a whole, half, or quarter kiln — or a set price like $15 for as many pieces as fit on a shelf or a 1×1 foot square — keeps billing simple, though it usually means saving up enough work to fill the space before you see finished pieces.

For contract firing (using someone else’s kiln without a studio membership), rates run higher: one studio charges contract firers $63 per cubic foot using studio glazes, or $52.50 per cubic foot for cone 10 work using the customer’s own glazes.

Minimum Charges and Extra Fees

Most studios set a minimum charge regardless of piece size — minimums often range from about $1.25 for low-fire bisque up to $2.00 for high-fire glaze work, and some studios also add rush fees (commonly around $20) if you need work fired faster than the normal 1–2 week turnaround.

What It Costs to Fire Your Own Kiln

If you own a kiln, the main ongoing cost is electricity, and it’s more affordable than most people assume.

The Formula

Kiln kW × Firing Hours × Duty Cycle % × Cost per kWh = Cost per Firing

• Duty cycle refers to how much of the firing time the elements are actually drawing full power (they cycle on and off to hold temperature). Bisque firings typically run around 50% duty cycle, while glaze firings run higher — around 60–65% — since the kiln works harder to reach and hold higher temperatures.
• Electricity rates vary significantly by state. The national residential average sits around $0.18/kWh as of early 2026, with states like Louisiana and Idaho closer to $0.10–$0.12/kWh, and Hawaii and parts of New England topping $0.30/kWh.

Worked Examples

• Small 120V hobby kiln: a compact kiln rated at 1.5 kW running a 2-hour program at a 60% duty cycle and $0.15/kWh costs a little over $1 for that firing — genuinely inexpensive for small, quick loads.
• Mid-size production kiln: an 11 kW kiln firing for 9 hours at a 55% duty cycle and $0.17/kWh works out to about $9.26 per firing.
• Full-size kiln, cone 6 glaze firing: an 11.5 kW kiln running a 12-hour cone 6 glaze firing at 65% duty cycle and $0.18/kWh costs around $16 per firing at the national average rate.

Across kiln sizes, a single firing on a medium hobby kiln usually falls in the $8–$20 range — often far less than people expect before they run the numbers.

The Full Cost of Ownership (Beyond Electricity)

Electricity is only part of the picture. Budget for:

• Element replacement: roughly $100–$200 every 100–200 firings
• Kiln wash and shelf maintenance: ongoing, relatively minor cost
• Occasional shelf or thermocouple replacement

Put together, ongoing monthly costs for a well-maintained kiln typically stay well under $30 with regular use.

Studio Firing vs. Owning: Which Is Cheaper?

The answer comes down to volume.

Community studios and shared kiln spaces typically charge $0.50–$1.50 per pound or $15–$50 per shelf per firing — meaning firing a couple of shelves twice a month at a studio adds up to $60–$200 monthly, or $720–$2,400 a year, just for firing.

Compare that to ownership: a quality mid-size electric kiln costs $1,500–$3,000 delivered, with each home firing running $5–$10 in electricity at average rates, plus modest maintenance costs.

Rule of thumb:

• Firing occasionally (a shelf or less per month): studio firing is usually cheaper and involves no upfront investment
• Firing regularly (multiple times per month): owning typically pays for itself within the first year or two, on top of the convenience of firing on your own schedule

Tips to Keep Firing Costs Down

• Trim more before firing. Less clay mass means smaller pieces, lower volume-based fees, and less wasted kiln space.
• Fire in full batches. Whether at a studio or with your own kiln, filling the kiln fully spreads the fixed costs of a firing across more pieces.
• Only buy a kiln as big as you actually need. Bigger, more powerful kilns cost more both to buy and to fire — a smaller kiln sized to your real output keeps firing costs consistently lower.
• Maintain your kiln properly. Old firebricks, worn elements, and poor lid seals force the kiln to work harder, raising the duty cycle and driving up cost per firing — regular maintenance protects both your budget and your kiln’s lifespan.

The Bottom Line

Expect to pay $5–$25 per piece for studio firing, or $5–$20 in electricity per firing if you own a kiln — with studio firing making more sense for occasional work and kiln ownership paying off once you’re firing multiple times a month. Ask any studio exactly how they calculate fees (by volume, weight, or shelf) before committing, since the billing method can meaningfully change your actual cost per piece.
