Buying a Pottery Kiln | Facts Features and What to Consider

Hobbyists looking for Electric Kilns to fire up Earthenware Pottery or Slip Cast Ceramics will find the market flooded with options. But not all of these Kilns can be good for the job.

When buying a Kiln, there are things you need to look for. Electric Kilns tend to be more popular than Gas-fired options because they produce different brighter colors with Oxidation firing. While some colors, like copper red, turn out better when fired in a Gas (reduction) Kiln, many Potters opt for an Electric option.

Carefully researching before purchasing your first or next Electric Kiln can help you choose the right one, whether you produce a few pottery pieces a month or are looking to establish a pottery business. This guide looks at 6 popular electric kilns suitable for your home studio and features six electric kilns that offer exceptional power and efficiency.

6 Popular Home Studio Kilns

• Skutt Kilnmaster – KM-1227-3
• Amaco Excel Kiln with EZ-Lift – EX270SF
• Amaco Excel 22” Deep Single Phase Kiln – EX-329SF
• Skutt Kilnmaster – KM-818
• Skutt Kilnmaster – KM-614-3
• Skutt FireBox 8×6 Kiln

But before we discuss these Kilns, we need to cover the features that a good Electric Pottery Kiln has. 

What Do You Need in a Good Pottery Kiln?

A good pottery Kiln will ideally offer even heating, be easy and safe to use, and last for many years to come.

Supports Higher Temperatures

Stoneware and porcelain typically need higher temperatures. Bisque and Glaze firing typically want to reach temperatures ranging from around 1789°F (976 C) Cone 07 to 2345 F (1285) Cone 10.  

Porcelain, Stoneware, and Porcelain glazes work best in even higher temperatures. You want your kiln to reach temperatures of 2345 F or 1285 C (Cone 10). The reason is that even if you fire lower, a Cone 10 Kiln will fire more efficiently and last longer. Also, if you ever want to or need to fire to Cone 10 you have the ability to do so. Again, you can always Lower the Temperature of a Higher Temperature Kiln, but you can never Fire Higher with a Low-Temperature Kiln. 

If you plan on firing low-fire earthenware clay and/or mid-fire stoneware or porcelain clay, then a kiln that fires to Cone 6 will work fine for your needs.

Heating Elements and Bricks Designed for Even-heating

A good Electric Kiln for pottery should ideally have 3-inch fire bricks for Insulation. They are more energy efficient, which is always a plus when it comes to your power bill.

One of the limitations of Electric Kilns is that they use radiant heat from heating elements for firing up your Pottery ware. Because there is no circulation to distribute the heat evenly around the piece, the section facing the heating element gets more heat than the section on the shady side. Heavier pieces of Pottery tend to be heated unevenly as a result. That’s why a 10-minute hold is recommended to ensure the whole kiln reaches the desired temperature.

Well-designed Thermocouple

The Thermocouple is technically the probe that senses the temperature in the Kiln and sends info to and from the controller for an accurate temperature reading. An expensive kiln may have type S platinum thermocouples that can last a decade or more even at Cone 10 firings. These are made of platinum and rhodium. 

Most Electric Kilns, however, come with type K thermocouples. These are inexpensive and made of chromel and alumel. How long type K Thermocouples last depends on your firing schedule and the firing temperatures. 

A Type that Fits Your Project 

If you intend to fire up little ceramic animals as a hobby at home, a 27-inch Electric Kiln is a waste of space and money. At the same time, firing up thick porcelain pieces evenly on a Cone 8 Electric Kiln to perfection may be difficult. You should buy a Kiln that fits your needs. If you only make a few pieces in a week, how long do you want to wait until you have enough greenware to fill your Kiln?  

Ergonomic Design

The ergonomic design means a Kiln that you don’t have to bend over too much to use safely. Top-loading models aren’t good for everyone. If you have a height disadvantage in the face of deep full-volume kilns, go for a front-loading model. They are pricier, but you’re paying for the lack of a backache from bending over too much. 

Many models come with a one-handed lid design. Such handles can be helpful if you intend to use your Kiln a lot.

Intend to move your Kiln around a lot? Look for models with wheeled stands. Most Kilns come with a stand without wheels. Wheel stands are great space savers. You can wheel your kiln out for use and back against the wall when you are done.

Reasonable Price 

Electric Kilns can go for $1000 to $15,000, depending on a variety of things. Usually, higher wattage, greater capacity, and better quality of the heating elements mean a higher price. 

Front-loading designs are typically more expensive. Top loaders are more popular. Paragon and Skutt are two popular brands to come out of the US with excellent industrial-standard kilns at surprising prices. 

Paragon is recommended for you if you have a big budget. Skutt models are more competitively priced. Skutt is known for its thermocouples, and the brand’s industrial-standard models are highly affordable for what they are. 

A Programmable Controller

Manual Controller:

Kilns can come with different types of controllers. Manual controllers are rare. These controllers need you to start your kiln at the lowest settings and change the temperature manually throughout the firing process. Note that manual controllers are not for beginners. 

The Set-Pro Control:

The Set-Pro Control is a standard 3-button controller that you’ll find on many Electric Ceramic Kilns. Some people find that it doesn’t give them the flexibility of 12-button or touchpad controllers. But the Set Pro is good for beginners or those on a low budget. 

The KMT Controller:

The KilnMaster by Skutt has a touchscreen controller similar to a smartphone with built-in WiFi that allows you to upgrade your firmware whenever Skutt comes out with a new feature, which gives you a new controller for the life of the kiln. I like the free App you can download and access directly to your phone. The App allows you to monitor the temperature of your Kiln and how long it’s been firing from anywhere you are. This touch screen was designed with beginners in mind. It will guild you through the process until you learn more about the firing process.

Select Fire Controller:

The Select Fire controller allows you greater control over your Firings. It’s two controllers in one. You can fire your own firing profile with multiple holds and ramps or by cone numbers. This is an easy controller to use.

Well-Ventilated Unit and Switch-Housing

You don’t want fumes and moisture to build up inside the Kiln during firing. This can rust the insides of the unit and affect the glaze. 

A good Electric Kiln will have Vents to work as an exhaust. During the firing process, you’ll want to remove the top peeper to let the fumes out. You may also prop the top up with a piece of fire brick that Skutt supplies with the kiln.

A switch housing with a solid metal top will not have good ventilation to prevent overheating. Ideally, the switch housing should have a metal grate or vents to allow airflow for cooling. Without airflow, the switches can overheat and fail. 

Efficient and Suitable Kiln Furniture 

A good Kiln manufacturer will offer good quality furniture that will heat quickly, lose as little heat as possible, and hold heat at the temperature that you want. 

One of the reasons that Electric Kilns can be inefficient is poorly designed Kiln furniture. Furniture includes bricks, shelves, bread racks (for wearable ceramics), Kiln posts, and stilts. Some materials are better than others. It’s best to order the furniture with your Kiln unless you want to pay for extra shipping charges later. 

Here are a few things to keep in mind when choosing Furniture Materials: 

• Kiln shelves are typically made of Cordierite, containing alumina and silica. They support firing up to Cone 10. But they tend to get warped beyond Cone 8.
  If you plan a lot of high fire projects, look for high-alumina kiln shelves. But if you can afford them, silicon carbide shelves are the lightest and least likely to warp. You need to take into account ware weight, temperature rating, and size of shelves for efficient and effective firing. 
• Support kiln shelves with Kiln posts. Using posts will maximize the space inside for the firing process. 

What Are the Installation Safety Measures?

Install your Kiln as per the manufacturer’s instructions and your local fire and electrical safety codes. That is the area you never want to get cheap.

Using a qualified technician keeps your insurance coverage valid,  just in case something goes awry. When it comes to electricity, you do NOT want to take any chances.

I strongly suggest getting a Licensed Electrician to check and make sure you can safely operate the kiln you are thinking of purchasing. I have found that Home Advisor (affiliate link) is an excellent choice for hiring an Electrician to ensure the safe and correct installation of any wiring, breaker boxes, or outlets.

After signing up for Home Advisor (no charge) up you will be connected with multiple contractors in your local geographic area.
You will then be able to ask your contractors questions to see if your Kiln is compatible with your electrical system before even setting up an appointment.

I had my Garage wired for my Skutt 818 Kiln and it took less than one hour. Be Safe and get a Licensed electrician.

6 Popular Home Studio Kilns

Now that we’ve got the basics out of the way let’s take a look at the Electric Kilns for your Home or Small Studio, from the larger to the smaller models.  

Skutt Kiln Master KM-1227-3 

This Skutt is a popular high-fire Kiln for larger pieces and higher production volume in your Home Shop or Small Professional Studio. The brand offers a huge range of lowfire to high-fire production Kilns. I have chosen the best-selling Skutt KM 1227 PK for a variety of reasons. 

This unit is larger in size, at 28.13 inches by 27 inches. It’s suitable for larger projects that need volumes of up to 9.9 cubic feet. 

This Kiln fires all the way to Cone 10. The precision Thermocouples increase the temperature accuracy and a host of other advanced features. Intermediate or seasoned users will appreciate the many high-level features of the model.

The elements are designed for even heating across various zones, with twice the number of grooves as most kilns of the same volume. There will be fewer cold spots when you use several shelves. The Skutt offers greater flexibility of use with its element placement and design. Elements will last longer, too, when there is less burden on each one. 

Thermocouples are exposed to greater accuracy. You have the option to upgrade to Type S to buff up your Skutt. Plus, the warranty on the model covers labor as well as parts.
