<DIV><FONT face=Arial size=2>That is/was not "Ivorine"! That be =

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 =
