_Cloisonné:_ In this work the design is done usually in coloured
enamels, which are separated one from another by means of ribs of
metal bent so as to follow the outlines of the design. These ribs are
placed on the plaque, and a drop of solder here and there keeps them in
place. The coloured enamels are filled in between these ribs and fired
as before explained.
_Champlevé:_ In this method the partitions between one colour and
another are formed by ridges of the base and not by separated ribs of
metal. These ridges are made by driving the metal with chasing tools
from the under side up and raising it above the surface. The spaces
between these walls are filled in with enamel, and it is all fired as
explained before.
The lid on the rose jar as shown in the group is an example of this
kind of enamelling.
