«Grand Feu» enamel
Usually white, beige or opaque, the "Great Fire" enamel dial has spread
widely since the 17th century. The term "Email or Enamel" is reserved for
vitrifiable products resulting from the fusion, vitrification or sintering of
a substance made of melted mineral materials at a temperature of at least 500°C.
«Guilloché and Flinqué» enamel
It is called "Guilloché" when the decoration is made on a Guilloché lathes.
The costs are quite high, and therefore reserved for a dial usually made of
precious metal as gold or silver.
« Champlevé » enamel
The Byzantine craftsmen took up and perfected a technique used by the Romans,
the engraver creates three-dimensional pockets cavities in a gold metal base and
the enameller deposits a glass paste or flow. This technique is called “Champlevé”.
Most of the Byzantine enamels known today date from the 9th to the 12th century.
The iconoclastic period between 726 and 787 has contributed to the destruction of
most pre-8th century examples, due to their iconographic nature. The "Champlevé"
enamel technique was created after the "Cloisonné".
« Cloisoné » enamel
The revival of a very ancient technique, dating well before the Middle Ages, and
extensively used extensively during the Byzantine Empire and in the West as early
as the 4th century, this method consists of creating compartments or housings
using gold wire in order to deposit the enamel with utmost precision.
Depending on the desired result, Donzé Cadrans decorates the base of the dial
either with a "Milanese" engraving (damier), a traditional engraving or sometimes
using the technique of "hand guilloche". The base plate for the "cloisonné" is
almost always 18 carat gold, as are the partitions.
