ABOUT
Hand Made Borosilicate and Dichroic Lampwork
These beads are individually handcrafted in the USA by a network of highly
skilled glass-blowers. They are fashioned in a torch flame by a process called
'lamp-working'. Unlike most beads, which are made from ordinary
or 'soft'
glass, these are created from 'hard' borosilicate glass. Only the finest
imported glass from Europe or the United States is used. Many of the coloured
glass is custom mixed. Borosilicate glass is worked at a much higher temperature
than ordinary glass and then kiln annealed at over 1000 degrees which makes for
a stronger more durable product. The higher the temperatures are also
responsible for rich natural colours.
Originally created for the Aerospace industry, dichroic chips are
incorporated in many of the beads. The brilliant optical properties of dichroic
glass are the result of multiple micro layers of metal oxides. These thin layers
of oxides have a total thickness of three to five millionth of an inch. NASA
developed dichroic glass for use in face shields in space suits. Multiple ultra
thin layers of different metals (gold, silver, titanium, chromium, aluminium,
zirconium, magnesium, silicon) are applied to the surface of the glass. The
glass is then kiln fired at extreme temperatures in a vacuum.
The resulting plate of dichroic glass can then be fused with other glass in
multiple firings. Certain wavelengths of light will either pass through or be
reflected causing an array of colour to be visible. Due to variations in the
firing process, individual results can never be exactly reproduced; each piece
of fused dichroic glass is unique and no two pieces are ever the same.
If making a large piece or set of jewellery, we suggest that you buy all
matching colour beads at the same time.
The main characteristics of Dichroic
Glass is that it has transmitted colour and a completely different reflective
colour. Furthermore, these two colours shift depending on angle view. With the
play of light together with its vibrant colour, dichroic glass is a prime tool
used to add interest to any piece of work or project.
