Cloisonné Factory

We visited a Cloisonné Factory and found the process very interesting.
They start with a copper item and they apply copper strips with a type
of glue in the desired pattern. Then it is fired at 800 degrees C
(1472 F) for 2 minutes. Then enamel is painted on using eye droppers
as seen in the picture; it is actually mineral stone powder (in dishes
in the picture) with water. It is applied then fired at 800 C for 4
minutes; the enamel will shrink so the enamel is re-applied and fired
about 5 times. It is then polished with peach wood that appeared to be
burnt.
