A hot iron and a wet rag, or even a hot gun may work without too much danger I guess. But too much hotness and celluloid goes on fire for sure (that is an element of Nobel power or dynamite if I recall correctly).

Was Ivory Keytops Once thought it was a good idea to use a sanding wheel on a Dremmel to "waterfall" a set of really badly chipped keytops on an old Acrosonic. Didn't actually set fire to the piano, but there was smoke and flame! Odd that this should be mentioned in a post today as I am about to do the same thing today on an old Gulbransen. But this time I will take my time and use a hand-held file. Boy Scout should carry old piano keys and a Dremmel in their backpacks. Alan R.

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? Best Regards, Joe Garrett, R.P.T. Captain, Tool Police 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.
