Famille-rose enamels were first introduced around the end of the 1720's for use on porcelain. The palette takes its name from a rose-colored enamel which makes up a characteristic color in the palette. Other significant colors in this palette are opaque yellow and opaque white.The famille rose is characterized by that an opaque glassy white (bo li bai) enamel (lead arsenate) is employed as the base for coloring garments or flower petals and that colored enamels are either mixed with white or brushed on top of it to created variations in tone. Typically the earlier enamels in this palette was applied with glue as its base which helped with building thick layers of enamels, while later versions are applied with the use of rue oil as a medium, which gives thinner layers. The vase has the label "YuDeTang" on the bottom. 14 x 5 inches.
