In addition, trays or teaboards of various sizes and shapes were sometimes used. They were usually circular or rectangular in form, occasionally of shaped or scalloped outline. Some trays were supported upon low feet; others had pierced or fretwork galleries or edges to prevent the utensils from slipping off. Wood or metal was the usual material, although ceramic trays were also used. At large gatherings a tray was often employed for passing refreshments (fig. 4). "A servant brings in on a silver tray the cups, the sugar bowl, the cream jugs, pats of butter, and smoked meat, which are offered to each individual," explained Ferdinand Bayard.[46] The principal use of the tray was, of course, to bring the tea equipage to the table. Whether placed on a bare or covered table, it arrived with the various pieces such as cups and saucers, spoons, containers for sugar and cream or milk, tongs, bowls, and dishes arranged about the teapot. [Illustration: Figure 10.--Pieces of a tea set of Crown-Derby porcelain, dating about 1790. The cups and saucers, covered sugar bowl, container for cream or milk, plate and bowls are ornamented with gilt borders and a scattering of blue flowers on a white ground (_USNM 54089-54095; Smithsonian photo 45541-A._)] Such tea furnishings of ceramic were sold in sets; that is, all pieces being of the same pattern. Newspaper advertisements in the 1730's specifically mention "Tea Setts," and later in the century ceramic imports continue to include "beautiful compleat Tea-Setts" (fig. 10). In the early 18th century, tea sets of silver were uncommon if not actually unique, though pieces were occasionally made to match existing items, and, in this way, a so-called set similar to the pieces seen in _Tea Party in the Time of George I_ (fig. 5) could be formed. However, by the latter part of the century the wealthier hostesses were able to purchase from among a "most elegant assortment of Silver Plate ... compleat Tea and Coffee services, plain and rich engraved."[47] When of metal, tea sets (fig. 11) usually consisted of a teapot, containers for sugar and cream or milk, and possibly a slop bowl, while ceramic sets, such as the one seen in _Family Group_ (fig. 1), included cups and saucers as well. [Illustration: Figure 11.--Silver tea set consisting of teapot, sugar bowl, container for cream or milk, and waste bowl, made by John McMullin, of Philadelphia, about 1800.
