50 Years of Building Kilns Better
Olympic had a customer interested in a 23-inch-wide kiln but needed it "stretched" for some of the items he was firing. Olympic took the stretched idea and created the first 25-inch oval in 1977. What had been a 10-sided kiln, 23 3/8-inch wide, became an oval 14-sided kiln with an interior width of 25-inches front-to-back and 37- inches long.
