Are you an aspiring glass artist considering fusing in your own home? Creating a home studio can be a great investment for a hobbyist wanting to take their passion to the next level, and an important step in that process is purchasing a kiln.
There are many aspects to consider as you begin your search for a glass fusing kiln, so to make the process less overwhelming, we’ve put together a guide addressing the most important things you’ll want to take into account.
At the end, we’ve also included our recommendations so that you can find the kiln that best fits your needs and interests.
When buying a kiln, there are many different factors to consider, both in terms of what you’re creating and the space in which you’ll be creating. Here are some of the most important questions to ask yourself:
Due to the fact that glass is a low-fire material, temperature maximums don’t vary significantly between different glass kiln models. However, depending on the project you’re making and the techniques you’re employing (tack fusing vs full fusing, for example), you will require different temperatures and firing schedules.
Consider not only the size and temperature needs for the pieces you want to create, but also how necessary it will be for your kiln to perform and maintain different programs and temperature changes easily.
Every time you fire, you will want to be able to fill your kiln to maximize efficiency, so to determine the size of the kiln you should buy, consider not only the dimensions of the pieces you’ll be making, but how many.
Before deciding on a kiln size and model, you’ll need to consider the maximum length, width, and height you’re willing to accommodate for. It’s also important to note that a glass kiln needs to be a minimum of 12 inches away from any walls. Additionally, be sure to think about what kind of ventilation the space has and what kind of access to breakers and outlets are available.
The bigger the kiln, the more energy is required to run it, so try to match the voltage and amperage requirements of your desired kiln to what you have available in the space you’ll be housing it. If you decide on a kiln that has higher energy requirements, be prepared to make further investments in its installation.
When sifting through the vast number and variety of kilns offered, it’s useful to have a list of specific qualities and characteristics you want your kiln to have. Here is an overview of attributes to consider when searching for your perfect match:
Unlike other materials fired in kilns, glass rarely fires over 1700 degrees Fahrenheit. Because it is a low-fire material, and due to its flat nature, even heat distribution is extremely important for fused glass firing.
It is possible to fire glass projects in a ceramics kiln, and you may be tempted to simply buy a ceramics kiln so that you can create art in different mediums. However, ceramics kilns typically only have side elements, while glass kilns insure that heat radiates not only from the sides, but from the top of the kiln as well. This helps counter glass’ sensitivity to temperature variation.
Also, shallower kilns are better for even heat distribution, so if this is something you are concerned about, be sure to look into the depth of the kiln you’re interested in purchasing.
When it comes to what procedures require which temperature ranges, slumping typically occurs between 1215-1250℉, tack fusing takes place between 1350-1370℉, contour fuse is around 1400-1450℉, and a full fuse occurs between 1450-1480℉.
All glass kilns should be capable of these temperatures, but consider how many of these firing procedures you’re likely to use when considering what kind of kiln controller might be a best fit for you.
Primarily, the size of the kiln you chose should depend on the types, size, and number of projects you intend to do, as well as the space you have available for the kiln itself.
In general, larger kilns take longer to heat up and cool down, so while they may be more practical for pieces larger in size, you will be able to fire more projects per day with a smaller kiln. Smaller kilns (up to 9” x 11”) are best for firing beads, jewelry, small pieces, and test items.
A kiln ranging in size from the aforementioned dimensions to 18” x 18” is perfect for those who are interested in creating slightly bigger fused glass pieces, shallow slumping, or more jewelry than can be fired in a single round in a small kiln.
A 23” x 27” kiln is a common purchasing size for average glass artists creating medium-sized fused pieces and deeper slumping projects, while anything larger than a 29” x 27” kiln is best for large production use.
Firing a full kiln is important to achieve maximum efficiency, so consider not only the size of what you’re firing, but how long it will take you to fill the kiln.
Soul Ceramics guarantees the lowest prices available, with glass fusing kilns ranging from just over $300 to close to $6,000.
Within the under $500 price range, Soul Ceramics offers the Jen-Ken GS-Fuse Box Glass Kiln for $322.99 and the Evenheat Glass Kiln Studio 8 for $447.99. Both of these are small, table-top kilns ideal for jewelry and small fusing projects.
On the other end of the spectrum are kilns like the Jen-Ken AFG Oval 9 Glass Kiln for $2,119.99 and the Evenheat Glass Kiln Studio Pro 41 for $3,689.99. These kilns are capable of firing the biggest pieces in a studio, come equipped with many special features, and are intended for very prolific artists or communal use.
Between the extremes are dozens of other kilns, ranging in both size and price.
Voltage and amps are two important elements to factor into your kiln decision as well.
The voltage of a normal household is 120V. For smaller kilns, this should not be a problem. However, larger kilns often require 240V; if you are interested in installing this kind of kiln in your home, you might want to consult an electrician.
Additionally, you will need to be certain you have a breaker that meets the amperage requirements for your kiln. First, determine how many amps you have available - look in the fuse/breaker box of the plug you want to use to see what number is indicated. Most U.S. homes are protected by 15-20 amp breakers, but a large kiln may require 40. Even if you have the correct voltage for a larger kiln, the kiln won’t work if the amp number is not high enough.
In general, the larger the kiln, the larger the energy requirements, thus providing another motive for beginners to start with a kiln smaller in size.
Considering location is important not only for the size kiln you purchase and electricity available; it can also determine the necessity of certain kiln attributes.
Mainly, if your kiln is going to be in a place that is frequently populated, like a studio, you’ll need to heavily consider ventilation needs. Make sure your kiln is near a window, and look at models with good venting systems. However, if your kiln is going to be in a garage or shed, where there aren’t a lot of people, you don’t need to worry about purchasing a kiln with an excellent venting system.
Additionally, based on where you’d like to place your kiln, you’ll need to consider its height. Many small glass fusing kilns are top-loading, meaning you’ll want to be sure your new kiln’s height, combined with the height of the stand you’re placing it on, isn’t too high for you to load it comfortably. Your kiln should stand about waist-high for easy loading.
All Soul Ceramics kilns come with a control, but most models offer you the choice of different types.
The most basic, elementary kilns come with a manual control, which requires you to start the kiln at the lowest setting and be responsible for all changes in temperature throughout the rest of the process. While this kind of control does require more effort, it also allows you the most power to regulate the firing process.
Electric controls are more expensive, but they are easier to operate, due to their ability to regulate temperatures independently. These range from the Set-Pro Control, a three-button system that lets you choose between 4 different firing programs, to the TAP Control, a touchscreen device that allows you to create your own personal firing program, chose one of many pre-programed options, or use its wifi connection to develop and edit programs from a computer, tablet, or phone.
For your first kiln, the argument can be made that the cheapest option - the manual control - is a smart choice, but on the other hand, an electric control is a good investment if you’re going to be doing a variety of firings, since reprogramming is a nuisance.
More detailed descriptions of specific controls we offer can be found here.
It’s a good idea to consider ordering furniture with your kiln so as to minimize shipping charges. Here are some of the most important accessories to consider investing in:
Kiln shelves: The benefit of using kiln shelves, as opposed to firing directly on the floor of your kiln, is that then the texture of the kiln floor won’t transfer onto the pieces you’re making; kiln shelves provide you a flat, untextured surface to fire on. Additionally, if you have an accident, kiln shelves can create a layer of protection between the hot glass and the floor bricks, which could be seriously damaged from the material.
Kiln posts: Kiln posts elevate shelves from the floor of the kiln and provide support while optimizing space within the kiln for firing. They are available to order in many different levels of thickness and height.
Bricks: Used as an insulator by lining the inside of a kiln, bricks come in a variety of shapes and two main materials. Hard bricks are strong and dense, and are great for structural support. Soft bricks are less capable of withstanding high temperatures, but retain heat more effectively.
Furniture kits: Instead of puzzling over what kinds of shelves, posts, bricks, or cleaning materials you need, one easy option is to invest in a furniture kit, which can be purchased automatically with many kilns offered from Soul Ceramics. Kiln furniture kits are an easy way to acquire the most essential accessories in a single purchase.
