Details of a cool way to make transparent metal
sheets, never heard of this before...indicates it
would be a good transducer for speakers, maybe even
electrostatically driven...conductive and transparent,
hmmm...;

TRANSPARENT METAL FOR RADIO
Sheets of metal such as iron, gold, or platinum so
thin that ordinary type can be read with ease through
them, may find use in radio and phonograph
reproducers.
Ordinary diaphragms for this purpose are so heavy that
they dampen some of the overtones and so coarsen the
sounds. These thin metal sheets are the result of
research by Dr. Carl Muller, of the Charlottenburg
Laboratory, near Berlin.
His method of preparing them is to electroplate the
metal on the surface of some soluble substance, such
as rock salt, and then dissolve away the support.
A ring of thicker metal can be used to support the
films, of which 2.5 million would have to be piled to
make a stack an inch high.
