Introduction

Process

The search for new techniques in material handling within the applied arts leads many artists to experiment with processes originally developed for industries such as engineering. This project explores the potential of laser processing with reference to the field of contemporary jewellery and aims to engage both engineering and art into productive conversation.

All pieces measure 48mm in diameter and are made using 0.6mm aircraft grade titanium, cut with a 35W Lumonics M35LS Nd: YAG pulsed laser using 3 bars of argon, 20Hz, 750v, speed of 24mm/min (increasing) and 660 pulse energy. The images (oxides) were applied using a 60W Universal CO2 pulsed laser at 100% power, 15% speed and 1000ppi. Variable oxide depths occurring on the titanium surface appear as different colours to the eye due to optical interference. Parameters are altered according to required colour. 3mm acrylic was cut at 100% power, 5% speed and 1000ppi, using a 60W CO2 laser. Pieces were manually assembled using oxidised sterling silver chain, reclaimed camera lenses and 12BA brass screws.

Concept The body of work Ocular series 1-6 is designed to attract the attention of art/design and science/engineering cultures and attempts to see the other’s point of view by offering a glimpse into the world of scientific research through the eye of a jeweller. The designs, based on the aesthetic of optical measuring equipment, are closely related to concepts of vision used in the English language: ‘seeing the bigger picture’, ‘clouded vision’’, ‘blurred vision’ to name a few. This is emphasized by the observation of engineers in scientific research, the scrutiny that accompanies their work and their test pieces that have, in their own right, become inspirational material for this project.

Results: Exhibition: ‘From Art to Engineering’ Figs. 1 to 6 illustrate three pieces from Ocular series 1-6 that track the successful development of titanium oxidation by laser for use in contemporary jewellery. The work will be exhibited within the engineering community in the foyer of George Begg building, February 21st - 28th 2007 (preview 21st Feb 6 - 8pm) and as part of the Ars Ornata Europeana jewellery conference, in the Manchester Museum, July/August 2007 (www.arsornata.org).
