Refractory ceramic coatings are sprayed onto the insides of kilns and on elements to achieve several goals. Coated elements are claimed to last up to 10 times longer. Coated kilns are more efficient and last longer. Coating technology has been developed into successful commercial products by Feriz Delkic ( pronounced Ferris) of International Technical Ceramics, Inc. Although ceramic coatings are expensive, they do save money in the long run.
