elry cast in bronze or silver would be coated with sil-
ver or gold respectively to give an impression of a
more valuable material.
DECORATIVE TECHNIQUES
Jewelry made by either casting or fabrication may be
further adorned by surface decoration, including
granulation, filigree, and inlays of stones or glass.
Filigree, also known as wire work, consists of pat-
terns of plain or decorative beaded wires soldered to
the surface of a piece of jewelry. In the fifth and
sixth centuries, wire was made by techniques called
strip twisting and block twisting, in which a strip of
metal is twisted, rolled, and hammered until it is ap-
proximately circular in section like a drinking straw.
Drawn wire, manufactured by pulling a thin metal
strip through a series of successively smaller round-
sectioned holes in a draw plate, gradually replaced
strip- or block-twisted wire from the seventh
through the ninth centuries in northern Europe.
A decorative technique called granulation con-
sists of soldering small spheres of gold or silver onto
the jewelry surface. Granules are simple to produce
by heating small pieces of metal until they roll up
due to surface tension, but they are difficult to sol-
der into place accurately. They were often used in
large quantity and in combination with filigree, so
individual mistakes are difficult to see without a mi-
croscope while the overall effect is impressive. Both
filigree and granulation created glittering effects
that are impressive by firelight.
Enameling and inlay of colored stones and cut
glass were also used to enhance the surface appear-
ance of jewelry with color, or polychrome, effects.
Cloisonné, a technique in which materials are set
into small cells (cloisons) fabricated by soldering up-
right strips of metal onto the surface of the jewelry,
was often used in the early medieval period. Garnet
cloisonné was used extensively on Merovingian jew-
elry. Well-known Early Anglo-Saxon examples are
the shoulder clasps from Sutton Hoo, in which cut
garnets as well as millefiori glass, composed of col-
ored glass rods fused together and sliced into thin
sections, are placed in cell work. Enameling during
the early medieval period was achieved by placing
broken or powdered glass within cells, which were
then heated, and the glass was allowed to melt and
fuse with the metal jewelry surface. Finally, glass was
also used to make colorful, patterned beads, as evi-
denced from workshops at Ribe in Denmark.
