How to Choose Your First Pottery Kiln
Buying your first pottery kiln can feel like a much bigger decision than buying your first pottery wheel.
There are different sizes.
Different firing temperatures.
Different electrical requirements.
Different controllers.
Different prices.
And suddenly you’re looking at a page full of numbers wondering:
“Which one do I actually need?”
The good news is that choosing a kiln doesn’t have to be complicated.
You don’t need the biggest kiln available, and you don’t need every feature on the market.
You need a kiln that matches the pottery you make, the clay and glazes you use, the space you have, and the power available where you live.
Here’s how to think about it.
1. Start With the Pottery You Want to Make
This should be your first question:
What am I actually going to fire?
If you’re making small mugs, bowls, ornaments, and small sculptures, you probably don’t need an enormous production kiln.
If you’re making large vases, platters, sculptures, or lots of pottery at once, chamber size becomes much more important.
A useful way to think about kiln size is:
Don’t buy based on what you make today alone. Think about what you realistically expect to make over the next few years.
Kiln manufacturers such as Skutt recommend considering the size of your largest pieces, how much pottery you expect to produce, and how your needs may grow over time.
You don’t want to buy a kiln that’s so small that you’re constantly wishing you had more space.
But buying a huge kiln that you rarely fill can also be unnecessary.
2. Pay Attention to the Kiln’s Firing Temperature
This is one of the most important specifications you’ll see.
You’ll often hear potters talk about:
- Low-fire
- Mid-fire
- High-fire
- Cone 06
- Cone 6
- Cone 10
These terms relate to the heatwork and firing range the kiln is designed to handle.
Your clay and glaze determine what temperature you need.
For example, if you’re working with a stoneware clay designed for Cone 6, you need a kiln capable of reaching that firing range reliably.
Skutt’s kiln-selection guide recommends choosing a kiln that meets—and preferably exceeds—the firing temperature required by your materials.
The important rule:
Choose your clay and glaze first. Choose the kiln second.
Don’t buy a kiln simply because it reaches an impressive temperature.
Buy one that works with the materials you actually intend to use.
3. Think About Kiln Size Differently
When manufacturers list kiln dimensions, it can be tempting to think:
“That sounds big enough.”
But remember that the usable firing chamber matters more than the outside dimensions.
Think about:
Width: Can your largest piece fit?
Height: Can you stack shelves efficiently?
Depth: Can you load your work without awkwardly squeezing pieces inside?
And remember that pottery needs space between pieces and appropriate shelf arrangements.
A kiln isn’t like a storage cabinet where you can simply pack everything tightly.
4. Check Your Electrical Supply Before Buying
This is one of the biggest mistakes a first-time kiln buyer can make.
You find the perfect kiln.
You order it.
Then you discover that your building doesn’t have the electrical supply required for it.
Not ideal.
Kilns can have specific requirements for voltage, amperage, and phase. Manufacturers recommend confirming the available electrical service before ordering, and having a qualified electrician evaluate the installation.
So before buying a kiln, find out:
- What voltage is available?
- What amperage can the circuit support?
- Is the supply single-phase or three-phase?
- Does the kiln require a dedicated circuit?
- Will electrical work be needed?
Don’t guess.
Have the electrical requirements checked professionally.
The exact requirements also vary by country and building, so local electrical codes matter.
5. Don’t Forget Ventilation and Placement
A kiln needs an appropriate location.
That means thinking beyond:
“Where do I have an empty corner?”
You’ll need to consider:
- Clearance around the kiln
- Flammable materials
- Heat
- Ventilation
- Electrical access
- Room temperature
- Safe access to the kiln
- Local building and electrical requirements
Manufacturers provide specific installation requirements, and those requirements should be followed rather than improvising a setup.
This is especially important if you’re considering installing a kiln at home.
A kiln isn’t something you should simply plug in wherever there’s an empty outlet.
6. Automatic Controls Are Worth Understanding
Modern electric kilns often have digital controllers that make firing considerably easier to manage.
Instead of manually adjusting the kiln throughout the firing, a programmable controller can follow a selected firing schedule.
For a beginner, this can make the process much less intimidating.
But don’t assume that an automatic controller means you can completely ignore the kiln.
You still need to understand your clay, glaze, firing schedule, kiln condition, and safety procedures.
Think of the controller as a tool—not a substitute for learning how firing works.
7. Think About the Cost Beyond the Kiln
The price on the kiln isn’t necessarily the final cost.
Your budget may also need to include:
- Electrical installation
- Ventilation
- Kiln shelves
- Shelf posts
- Kiln furniture
- Witness cones
- Maintenance
- Replacement elements
- Other replacement parts
Depending on your setup, installation can become a significant part of the overall investment.
That’s why it’s better to ask:
“What will my complete kiln setup cost?”
rather than:
“How much does the kiln cost?”
8. Should You Buy New or Used?
A used kiln can look tempting.
Especially when you see one being sold for a fraction of the price of a new model.
But this is where you need to slow down.
Kilns contain components that wear over time.
Heating elements, thermocouples, relays, wiring, insulation, controllers, and other parts can require replacement.
If you’re considering a used kiln, you need to know:
- Its age
- Its model number
- Its firing temperature rating
- Its electrical requirements
- Whether replacement parts are still available
- How frequently it was used
- Whether it has been properly maintained
- Whether the electrical components are in good condition
If you don’t know what you’re looking at, getting advice from an experienced potter or qualified technician before purchasing can save you from an expensive mistake.
9. Don’t Automatically Buy the Biggest Kiln
Bigger isn’t always better.
A larger kiln can be useful if you regularly produce large amounts of pottery.
But if you’re making a few mugs and bowls every week, a massive kiln may simply be more equipment than you need.
Think about your actual production.
What do you make?
How often do you fire?
How large are your pieces?
How much do you realistically expect to make?
Those answers should guide the size you choose.
10. Don’t Buy the Cheapest Kiln Just Because It’s Cheap
Price matters.
But reliability matters too.
Your kiln is responsible for the final stage of turning your carefully made pottery into ceramic.
A cheap kiln that struggles to reach the required temperature—or produces inconsistent firing—can cost you more in the long run through wasted clay, glaze, time, and finished pieces.
Look beyond the initial price.
Consider:
Build quality
Controller quality
Replacement parts
Manufacturer support
Warranty
Service availability
Electrical requirements
Firing capability
You’re not just buying a metal box that gets hot.
You’re buying a piece of equipment you’ll depend on for your pottery.
11. Ask These Questions Before You Buy
Before handing over your money, write down the answers to these questions:
About your pottery
- What clay will I use?
- What glaze will I use?
- What cone or firing temperature do they require?
- What’s the largest piece I’ll make?
About the kiln
- What’s the internal chamber size?
- What’s its maximum firing temperature?
- What electrical supply does it require?
- Does it have a programmable controller?
- Are replacement parts available?
- Is technical support available?
About your studio
- Where will the kiln go?
- Is the location appropriate?
- Is there adequate ventilation?
- Can the electrical system support it?
- What installation requirements apply locally?
If you can answer those questions, you’re already much closer to making an informed choice.
12. Your First Kiln Doesn’t Need to Be Your Forever Kiln
This is something worth remembering.
Your first kiln doesn’t have to be the kiln you’ll own for the next twenty years.
Your pottery will change.
Your production may increase.
Your pieces may become larger.
You might eventually start firing different clay bodies or glazes.
Your studio may change too.
So don’t put enormous pressure on yourself to predict your entire pottery future.
Choose something appropriate for where you are now and where you’re realistically headed.
The Bottom Line
Choosing your first pottery kiln isn’t about finding the biggest, cheapest, or most powerful model.
It’s about finding the right match.
Start with your clay.
Then your glaze.
Then your desired firing temperature.
Then think about chamber size.
After that, check your electrical supply, installation requirements, ventilation, and total budget.
And don’t be afraid to ask for help.
A good kiln supplier, experienced potter, or qualified electrician can answer questions that are difficult to solve from a product page alone.
Your kiln is going to become an important part of your pottery journey.
Choose it based on the pottery you actually want to make—not simply the specifications that look impressive on paper.
