Holloware
Hollow bangles, earrings and other Jewelry can be produced by various techniques
in which carat gold strip is formed into tubes by drawing it through steel dies.
These can be plain tubes or textured, with twists, spirals and other shapes.
These can then be shaped into circles and other shapes by wrapping it around
dies. These can be welded or soldered seamless tubes or more simply seamed
tubes. Often a base metal core is used around which the tube is formed and
supported. This has to be removed by chemical dissolution at the end of the
process.
Generally end-fittings or findings may be soldered on to give a final piece of
Jewelry. Final decoration consists of polishing or texturing (e.g. by sand
blasting) and may include diamond faceting to produce a decorative pattern of
bright facets.
