All you ever wanted to know about Cloisonné Pins but were afraid to ask...

(Jack is so proud of himself for discovering how to pronounce "Cloisonné") ...  kloyz-uh-NAY, or klwahz-uh-NAY.

Enameling is the technique used to cover metal with colored glass in order to produce stunning pieces of jewelry and decorative items. The glass, which is usually used in a powdered form, is fused to the metal by heat to form a strong bond between the two materials.

Cloisonné, is from the French "cloison" meaning "compartment" or "partition."
This technique involves laying out a design on a metal base with thin gold, copper, or silver wire. Then the cloisons or "partitions" of the design are carefully hand filled using fine brushes or droppers with finely powdered colored glass which, when fired at around 1700 degrees fahrenheit, bonds the glass to the metal with a jewel-like quality.

More FYI:

• Color variations are not created by mixing pigments, but by meticulously layering colors.

• Cloisonné first developed in the jewelry of the ancient Near East, typically in very small pieces such as rings, with thin wire forming the cloisons, and in the jewelry of Ancient Egypt, including the jewels of the Pharaohs.  The most elaborate and highly-valued Chinese cloisonné pieces are from the early Ming Dynasty.

• Cloisonné art appeared as "Critter Pins" which were collected, worn on clothing, or attached to quilts as early as 2012 and were developed by a quilt design establishment known as Brandywine Design.
