CLEMENT HEATON (1861-1940) ARTS & CRAFTS JARDINIERE, CIRCA 1890 copper with applied cloisonné decoration (20cm high) Note: Clement Heaton, an early member of A.H. Mackmurdo’s Century Guild, set up his company Heatons Cloisonné-Mosaic Ltd at 6 Berners Street, London in 1887, a year after selling his share in his father’s lucrative stained glass business Heaton, Butler & Bayne for £4,800. He patented his enamelling technique in 1886, inspired by medieval techniques that precluded the firing process and instead used coloured cements: a mixture of resin, beeswax, sulphur marble dust and coloured pigments. Hardening over time, these cements could be polished to give the soft matt finish characteristic of Heaton’s work as seen in the present example.
