Types of Kilns
Electric Kilns
Electric kilns are the most common type found among hobbyists and smaller studios. They are user-friendly and capable of reaching high temperatures, making them ideal for pottery and ceramics. Brands like Skutt and Paragon are popular choices. These kilns usually require a dedicated electrical circuit.
Gas Kilns
Gas kilns are favored for their ability to achieve specific atmospheric conditions. They offer a unique aesthetic, often producing richer colors in glazes. Gas kilns can be front-loading or top-loading and are typically more complex to operate. They are suitable for professional potters who want to experiment with various firing techniques.
Raku Kilns
Raku kilns are designed specifically for raku firing, a technique that involves removing pottery from the kiln while it is still hot and placing it in combustible materials. This creates unique surface effects. Raku kilns can be gas or electric, and they are generally portable, making them popular for workshops.
Wood Kilns
Wood kilns are traditional kilns that require wood as a fuel source. They are typically larger and suitable for professional potters aiming for specific effects in their work. The firing process can take several days and requires careful temperature control.
Vacuum Kilns
Vacuum kilns are specialized for drying wood and ceramics without the risk of cracking. They operate at lower temperatures and are efficient for drying dense materials. These kilns are less common in pottery but are valuable for woodworkers and specialty ceramic applications.
Salt Kilns
Salt kilns use salt during the firing process to create a unique glaze effect. The salt vapor reacts with the clay body, producing a distinctive surface quality. This technique is more advanced and generally used by experienced potters.
Factors to Consider When Buying a Used Kiln
Condition of the Kiln
When purchasing a used kiln, it’s essential to inspect its condition thoroughly. Look for signs of wear, damage, and any modifications. Ensure that all electrical components are intact, and check for any rust or corrosion, especially in gas kilns.
Age and Usage History
Understanding the age of the kiln and its usage history can give you insights into its reliability. A kiln that has been used frequently may require more maintenance. Ask the seller about how often it was used and for what types of projects.
Brand Reputation
Certain brands are known for their durability and quality. Brands like Skutt, Cress, and L&L are respected in the pottery community. Research the brand before making a purchase to ensure it meets your needs.
Size and Capacity
Consider the size and capacity of the kiln based on your projects. Smaller kilns may be suitable for hobbyists, while larger kilns are necessary for professional potters or educational institutions. Measure your workspace to ensure the kiln fits comfortably.
Temperature Range
Different kilns have varying temperature ranges. Ensure that the kiln you are considering can reach the temperatures required for your specific projects. For example, if you plan to fire stoneware, ensure the kiln can reach at least cone 5.
Where to Find Used Kilns
Online Marketplaces
Websites such as surplusrecord.com and machinio.com offer listings for used kilns from various sellers. These platforms often have a wide range of options, allowing you to compare prices and conditions easily.
