Technical Information
Dichroic means more than one colour and is produced through a process called thin film physics. In a heated vacuum chamber metals and minerals are vapourised by electron beams. The vapours rise and grow on the glass as metal crystals. On clear glass one colour is reflected while another is transmitted when light is allowed to pass through it. On black glass the dichroic layer will reflect all the light giving an intense metallic colour. Note that it is difficult to photograph clear dichroic glass and successfully capture the rainbows within it as movement is needed to release them.
The necklaces are worn quite short and are usually sixteen to seventeen inches long. Longer or shorter can be ordered. All metalwork used is silver. Generally a large bolt ring is used as a clasp which is robust and easy to use. Sometimes a bayonet or magnetic clasp is used depending on the style. No glues are used. Bracelets and earrings are made to match. Necklaces can be worn in water. They can be cleaned by washing in warm soapy water and rinsed.
