Mason's Ironstone was made by the English pottery of Charles J. Mason after 1813. Mason, of Lane Delph, was given a patent for this improved earthenware. He usually called it Mason’s Patent Ironstone China. It resisted chipping and breaking, so it became popular for dinnerware and other table service dishes. Vases and other decorative pieces were also made. The ironstone was decorated with orange, blue, gold, and other colors, often in Japanese-inspired designs. The firm had financial difficulties but the molds and the name Mason were used by many owners through the years, including Francis Morley, Taylor Ashworth, George L. Ashworth, and John Shaw. Mason’s joined the Wedgwood group in 1973 and the name was used for a few years and then dropped.
