Vitreous enamel, also called porcelain enamel, is a material made by fusing powdered glass to a substrate by firing, usually between 750 and 850 °C (1,380 and 1,560 °F). The powder melts, flows, and then hardens to a smooth, durable vitreous coating.
The firing temperatures of such glazes are low, in the region of 950 – 1000 °C because of the variable degrees of solution of the individual oxides. [8] The amount of tin oxide used for coloured glazes depends upon the opacifying property of the chosen chromophore and the intensity of the colour desired; if a deep colour is required less ...
Until recent centuries the enamel firing was done holding the vessel in a furnace on a pontil (long iron rod), with the glassmaker paying careful attention to any changes in the shape. Many pieces show two pontil marks on the base, where the pontil intruded on the glass, showing it had been on the furnace twice, before and after the enamels ...
