Similarly, in figures, for many reasons they should have no jutting arms or over out-thrust ornaments. First because in use they will be broken off. A glance at the damaged specimens on the china shelf will at once show the mistakes of the potter. Rarely at the Copenhagen factory did the modeller fancy for the moment he was a silver-worker and leave a projecting arm. There is one instance in an old figure most noticeable. A seller of _kringler_ has an outstretched hand offering his ware for sale, but that is missing in the example the writer examined. Another reason for the avoidance of undue extension is the technical difficulty of supporting this in the oven during firing. Clay in the oven requires every assistance to keep it from warping or bending over, and to introduce unnecessary difficulties in modelling is to produce bad art. This, coupled with the fact that porcelain shrinks in firing to about six-sevenths of its original size, is sufficient reason for the artistic potter to keep strictly within the limitations of his technique. =The Sound Principles of Old Copenhagen Porcelain.=--Throughout the Müller period it will be seen how carefully these axioms were followed. In regard to the styles of decoration, the old school worked in overglaze painting and the Renaissance school employs underglaze painting. They are in complete contrast to one another in the treatment of a subject. The narrow range of underglaze colours in a measure limits the results of the decorator of figures. But it must not be imagined that the overglaze school of painting, by reason of its freer palette, allowed the modelling of the figures to be less than ideal. A reference to the Müller chapter on _Figure Subjects_ will show that a great many examples were produced in white or in biscuit, and were thus entirely independent of colour to help out any deficiencies in modelling, if such existed. An indication of the strong individuality of the figure modelling of the Juliane Marie period, is forthcoming in the fact that the factory to-day is producing some of the coloured figures of that period in white.
