Figure 13.

Raman spectra recorded on European (glaze 1, orange 1, dark blue 1), Chinese Famille rose (dark blue lm, blue La, dark blue Fr, black line Q, pink La, black line Q and yellow green La) and wucai plates (green w) for different colored enamels representative of the 18th century enameling recipes (see reference [23]). Details for Famille rose overglaze are given on the right. Note the variation of the Raman spectrum and fluorescence background of blue enamel with color density in the same area.
