Vernon Kilns was the name used by Vernon Potteries, Ltd. The company, which started in 1912 in Vernon, California, was originally called Poxon China. In 1931 the company was sold and renamed Vernon Kilns. It made dinnerware and figurines until it went out of business in 1953. Their main competition was J A Bauer and Pacific Clay Products.

The bread & butter plates measure 6 3/8" across. All pieces are stamped with a version of "Ultra California - Vernon Kilns Authentic California Pottery - Made in U.S.A."
