Vintage Masons Mandalay Covered Cheese Dish with Wedge. 9x7 1/2x4 tall. Hand decorated in 22 carat Gold. Good condition. PROVENANCE: A Charleston South Carolina Private Estate. 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. Some experts believe the name ironstone came from the slag, but others think it came from the fact that the ware was as hard as iron. It was usually called Mason's Patent Ironstone China. It resisted chipping and breaking so it became popular for dinnerwares 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. Mason's 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 is still found on dinnerwares. Wt. 2 1/2 pds
