Volcanic Series (latest work)
Challenge: To express and capture the physical aspects of
colour, pattern and texture of our local volcanic landscape,
and express something of the immense untapped energy of this
environment in glass.
After all, Obsidian (naturally occurring glass) is the result
of volcanic activity and it seemed obvious to me that the
medium of hot glass lended itself perfectly to expressing
the textures and colour of geothermal activity.
This led to a period of experimentation and research into
a technique developed hundreds of years ago, aimed at producing
a crackle effect on the exterior of a glass vessels.
This technique involves plunging blown glass at about 800
degrees celsius into cold water. The resulting abrupt release
of energy, and thermal shock of the sudden change of temperature
produces the external crackling texture revealing the underlying
transparency that is best revealed by displaying the work
in natural sunlight or with artificial lighting. Some pieces
are Acid Etched resulting in a ceramic matt finish.
