ivory grain in
plastic.  The most common was probably "Ivorine," which has striations
(faint bluish lines, spaced about a millimeter apart) running the long way
through the keytops -- it's kinda hokey and looks not at all like ivory..."

David, et al,
That is/was not "Ivorine"! That be Celluloid! The flammable, stinky stuff,
used in the first part of the 20th Century. Ivorine is the good plastic that
many of use replace keytops with. The name "Ivorine" was the trade name used
by Tuners Supply and is essentially "Pyralin", which is an Industry name for
a specific type of plastic. It is sold by Schaff. Many pianos, even pre-1900
had Celluloid fronts with Ivory tops. The better quality stuff lasts
forever, and is the precursor of the Pyralin. K?

Sorry.  I assumed that because I ordered "Ivorine" keytops once from Tuners
Supply and got the ones with the blue lines.  Still have 'em in the original
wrapper.  --D.N.
