99% of all top loading kilns are made of K23 soft brick. The brick is relatively inexpensive and provides excellent insulation value. However, this brick is very fragile and can be easily damaged.

How it works

KilnShield® is placed on the top layer of bricks where you lean on to the kiln to load and unload. When you are finished remove the shield and close the kiln lid to fire or rest. KilnShield® will give you peace of mind, speed up the loading time and put less strain on your back.

How it's made

We use high-quality materials that are resilient to heat up to 250 degrees Fahrenheit for those times when you just can’t wait. Our Lifetime Warranty offers years of use and kiln preservation. We use 16 gauge galvanized steel for the base and 1/4¨ soft silicone foam for the top. Our design is customized to your kiln, insuring proper and accurate fit. (Some assembly required)

How it protects

KilnShield®’s design protects the soft brick from being damaged with heavy gauge galvanized steel and provides a soft silicone foam cushion for a pleasant loading experience. You can focus on loading the kiln not damaging your investment, with less strain!


Out Story

Tony Nardella, as owner of Boston Kiln Sales & Service, has been servicing kilns in the New England area for over 20 years. During that time, he found the leading factor in kiln deterioration was the gap created by worn and chipped top bricks. To prevent this damage, he developed and patented KilnShield® to a shield to protect this very vulnerable section of the kiln. This keeps kilns running efficiently and helps users during loading and unloading. 

The Benefits

Deterioration between the top brick and lid leads to inefficient firing, as well as caustic fumes to escape into the studio space. KilnShield® prevents this deterioration greatly increasing the life of the kiln, saving costly repairs, and benefiting the studio environment. In addition, the shield equally displaces your weight while loading making the process easier and causing less strain on your back. KilnShield® is 1/4 the cost of brick replacement prolonging your investment and putting your hard-earned money towards art!

The Design

Our design provides a strong and smooth metal surface to protect the brick. For your comfort, we added a soft silicone foam pad to lean on during loading and unloading of the kiln. The shield comes with holes
for hanging or magnets can be purchased for mounting to the kiln control panel for easy access.


Your Investment

A kiln is typically each studio’s largest investment. It’s performance and efficiency are crucial. As durable as a kiln appears the most delicate and important part is the top layer of brick.

Life of the Kiln

An important and often overlooked factor to the longevity of a kiln is the seal between the top layer of brick and the lid. A good tight seal is crucial for energy efficient firings and proper venting of fumes. The escape of fumes from damaged top layer bricks is the largest contributor of damage to a kiln beside the temperature and frequency of firings.

Vital Protection

The most common damage to the top layer of brick is done during loading and unloading of the kiln. The very soft and brittle brick is susceptible to degradation from leaning on it, scraping of clothing, shelves, and the pottery itself. The KilnShield® provides a hard and smooth surface that will protect the brick from the friction of the daily wear.
