Techniques: 1780-1807: Line engraved transfers with heavier cruder designs and a minimum of shading. In 1807 stippling was introduced, using many small dots to produce more precise, shaded, dimensional designs. Motifs before about 1815 are predominantly Chinese-inspired, and between about 1815 and 1830 landscapes and historical scenes were popular. Romantic views predominate after ca. 1830. Colors Blue- 1784-1840; Brown introduced - 1809; Dark (almost navy) blue - 1818-1830; Red, Green, Purple introduced - 1829. These chronological indicators also apply to whitewares.
