Willets China

Q:        I inherited my grandmother’s set of china. The dishes are decorated with red and yellow roses. Each one has an octagonal mark with “Semi W.M. Co. Porcelain” inside it. Can you tell me who made this china and how old it is?

A:         Willets Manufacturing Co. of Trenton, N.J., made your dishes. The pottery was in business from 1879 to about 1912. It used the octagonal mark on semi-porcelain made between 1879 and 1909.
