Over the several years I spent developing my crystal mouthpieces, I researched glasses and crystals, as well as methods of working with them to produce the complicated geometries in a flute headjoint. In order to see my experiments through to the logical conclusion, I decided to build an entire modern flute out of glass. Two of these instruments were made. They featured redesigned key work out of sterling silver and the body material of quartz crystal. The tone of this instrument is truly unique, dark and woody, and at the same time, clear and transparent. In the end this instrument also proved invaluable studying the vortexes and air turbulence behavior within the sound column.
