This pretty set of four salad plates were made by the pottery established by William Adams in Staffordshire, England. The hand painted flowers are predominantly in shades of ruby red with green foliage, with one central flower in golden yellow. The rims are decorated with floral sprays and red diamonds composed of 4 dots, and they're edged in a narrow line of green, all against the pale ivory china.
The backstamp has "ADAMS" across an oblong tablet, surrounded on the four sides by "ESTBd 1657 ROYAL IVORY ENGLAND," followed by "TITIAN WARE Hand Painted" and the Registered Design Number of "Rd 459174." This mark used from 1896 into the twentieth century; the presence of the word "England" indicates it was made after 1891 for export to the U.S. The design registration number is for the pattern, which was registered in 1905 according to English Registry records. This number was used on a variety of Adams patterns, however; the pattern name is not included on the mark and we've been unable to identify it but it is not a common one (Replacements.com identifies it as pattern ADA121). We're dating these from the 1920's.
Each plate measures 8 inches across, with a flat center and a dished rim 1 1/4 inches wide. Weighing about 11 ounces apiece (2 3/4 pounds for the set before packaging), they are in excellent condition with no cracks or chips. The clear glaze on the back of one of the plates is crazed but clean and unstained, while the fronts are pristine. There are a few glaze pops and each plate has three evenly spaced tiny stilt marks on the back. They all appear as new and are ready to use and display beautifully.
