1785. Round in shape on collette foot; scroll piercing. Circular lid surmounted by knob. (_In the collection of B. B. Harrison, Esq._) 1790. Vase shaped on collette foot. Bead edging and beaded handle. Star piercing. All these examples have blue glass liners. (_In the collection of B. B. Harrison, Esq._)] [Illustration: DESIGNS OF MUSTARD POTS. From an old Pattern Book issued by eighteenth-century Sheffield platers to Continental markets. Many are by J. Parsons & Co., about 1784. The fine character of the cut and pierced ornament indicates the artistic output of that period. (_At the Victoria and Albert Museum._) (_Reproduced by permission of the Board of Education._)] Their shapes varied with varying fashions. The illustration (p. 145) taken from an old Design Book by J. Parsons and Co. of Sheffield, about 1784, shows the type then fashionable. All these are of oblong form. The lids spring up with fine contour and are chased with various patterns, all of them terminate in an urn pediment, following the prevailing note in decoration. As was shown with salt cellars in regard to these old pattern books the designs are only slight variations from each other, differentiated from each other by numbers for trade reasons. But the differences are trifling, as will be seen from the illustration. The middle examples on the two rows illustrate this. The same ostrich feathers, a simulation of the _fleur-de-lys_, and later in Hepplewhite manner to be affiliated with the Prince of Wales's feathers as a permanent feature in design. In both examples this is a feature as a pierced medallion. The floral festoons are the same in both cases, but the only variation is the chasing in the upper and lower bands. The other examples show similar relationship. During the period of classic design there was a drum-shaped upright form as is shown in the illustration (p. 149) with handle and lid, by the way, which go to an earlier period. The adjacent example, 1785 in date, is oval, like the copper-plate pattern book examples illustrated, but its character is finer. The pierced designs as in the 1775 example are of a fine quality. The thumb piece at the handle, it may be noted, goes back to seventeenth century days and is found in flagons.
