here is a piece written before Shure Inc. purchased the rights to Roswellite for use in their KSM313 and KSM353 Ribbon Microphones. If you haven't heard, Shure Inc. manufactures the mics in Illinois, using the same methods, materials and tooling that we used at Crowley and Tripp.
ONLY Shure has this material. No other ribbon microphone manufacturers have it.
Here is a link to that article in which the naming of Roswellite is mentioned. It happened at Tape Op Con 2007, and was helped by some of the attendees who were at the booth who had a hard time with "acoustic nanofilm", which meant nothing to them, but a world to us!
