CIRCA 1885-95, INCISED NUMERAL 6

Flambé (or sang de boeuf) glaze was developed in China during the Ming dynasty during the reign of Wanli (1573-1620) and the technique refined during the Quing dynasty and the reign of Qianlong (1736–96). In France in the 1880's the chemist Georges Vogt, assisted by Charles Lauth, succeeded in imitating the glaze and produced a formula which was used at the Sèvres manufactory to great success. See Marie-Nöelle Pinot de Villechenon, Sèvres, (London, 1997), pp. 102-103, pl. 102-103 for examples made at Sèvres.
