But the vases bearing the Chelsea-Derby mark of an anchor crossing the down-stroke of the letter D ([Pl. e]. 73) differ from those made by Sprimont not only in outline. A new scheme of decoration has come in, one that continued with no radical change for the next fifty years and more. Let us take the Chelsea-Derby vase in the Jones collection—it stands in company with several others of the Sprimont rococo type. Notice the oblique fluted mouldings of the upper part (a motif taken directly from the silversmith), which are accentuated by deep blue and gold lines on a white ground (this is a scheme of decoration above all characteristic of Derby china). The reserved panels on the body of the vase are painted with pastoral subjects. Here there is little change, but around these panels the ground is completely covered with flowers of various kinds—each species can be made out, but full-blown double roses predominate. These full-blown roses are a note that distinguishes English porcelain from this time onwards. As they become larger, and occupy a more prominent place, the painting loses all trace of decorative feeling. Billingsley carried them in his wanderings to all the porcelain factories of England, and we are finally landed in the monstrosities of Rockingham and the insipidities of Nantgarw.
One point we have omitted to mention in our description of the Chelsea-Derby vase at South Kensington. The handles, winged figures somewhat classically treated, are of unglazed ware. This is an example of the famous Derby biscuit, or bisque, as it is sometimes called, which we now know was made as early as 1771. The greatest care was taken in the preparation of this biscuit ware; any piece with the slightest defect was rejected. The material allows of a sharpness and high finish which would be lost in the thick covering of the glazed ware. The paste in many of the examples has acquired a somewhat shiny surface, as if covered with a skin of glaze. The best known specimens date from the last years of the century, when Spengler, a modeller from Zurich, was engaged by the second Duesbury. In them we see exemplified that mixture of the sentimental and the pseudo-classical so much admired at this time. The shepherd with his dog (there is an example at South Kensington) is taken from a Roman relief, the head perhaps from an Antinous. The shepherdess has been reading Richardson, if not Jean Jacques, and they both take life very seriously.
We find, however, the Chelsea-Derby mark on enamelled figures that differ little from the earlier and more frivolous type. These survivals, as it were, of the rococo school stand no longer upon a scroll pediment, but on a rocky ground, amid careful reproductions of natural objects, stumps of trees, shells, or what not. The colours, too, have become somewhat stronger; the pale, greenish blue of the earlier pieces is replaced by a fuller turquoise hue.
It was at this time, or a little later, that the process of ‘casting’ was introduced for these statuettes. This was a process of English origin, though it is now extensively used at Sèvres and elsewhere abroad. We have described the various modifications of this plan in a previous chapter ([p. 25]). In the case of these statuettes, the figure is first modelled in tough clay; the head and limbs are then cut off. A plaster-of-Paris mould is then made of each of the separate parts, a cream-like slip is poured into the mould and quickly poured out before all the water is absorbed, a layer of the paste remaining on the sides of the mould. This layer is detached when sufficiently dry; the pieces are then joined together by means of the same slip, and the outline of the figure sharpened with a modelling tool.[234] Porcelain made by this casting process is not so dense as that made on the old system; its specific gravity is appreciably lower. The moulding or repairing knife may be, to some extent, replaced by the use of a brush, but a less sharp outline is obtained in this case. In the furnace these figures have to be supported by an elaborate scaffolding of props, and the shrinkage of the clay during the firing is another source of difficulty.
In the British Museum may be seen a garniture of vases, of a type very characteristic of the early Chelsea-Derby time. A pale turquoise ground is overlaid with white flowers in low relief. This is but a modification of the German schnee-ball decoration. Somewhat later the pâte tendre of Sèvres is evidently taken as a model, as in the cabaret which was given by Queen Charlotte to one of her maids of honour. This ‘equipage,’ to give it its English name, has also found its way into our national collection. It has the rare jonquil ground with a border of blue and gold.
For smaller objects, for cups, saucers, and plates, a simpler style of decoration is in favour. The wreaths of little blue flowers, forget-me-nots, and corn-flowers (the French barbeau), relieved with touches of green and gold, remind one of the similar ware made at Sèvres, and more especially at some of the smaller Parisian factories during the early years of Louis xvi.
The elaborately decorated ‘old Japan’ was much copied at Derby, but so unintelligently that the patterns degenerated into meaningless forms, known as ‘rock Japan,’ ‘witches Japan,’ and even ‘Grecian Japan’! This was the beginning of a barbarous style of decoration, in vogue in the Staffordshire potteries at a later time both for porcelain and earthenware, in which scattered members of the original scheme are jumbled together at the whim of the ignorant painter.[235]
The subsequent vicissitudes of the Derby factory may be traced in the marks in use at successive dates. The combined anchor and D was apparently employed at Chelsea as long as the factory existed, but at Derby a crown with jewelled bows was introduced in 1773 ([Pl. e]. 75), perhaps on the occasion of some velléité of royal patronage, although we have no definite evidence of anything of the kind.[236]
Somewhat later we find two batons crossed, with three dots in each angle (similar to the ‘billiard’ mark on some Dutch porcelain) inserted on Derby porcelain between the crown and the letter D ([Pl. e]. 74).
