--can you still salvage the wooden keys to re-top them with plastic? or will the water/chemical mess up the wood?

Sorry, but I have never tried soaking off the key tops on "good" keys--have always thrown away the wood after retrieving the tops, but I would assume that they would be no good for future use.

Thanks Wayne, That's what i figured. The Ivories do seem slick though (almost like plastic) what can be done to add some grip to them?

I do have a Plant light that i will get up and running. Thanks guys

Hey Brown,
I talked with an Ivory Tech in Boston who said that Peroxide will un-glue the ivories and should only be used when soaking them. What do you think?

I really appreciate everyones input...

i ordered some key tops (ivory that were yellower than i hoped. i scrubbed them with Arm and Hammer whitening toothpaste for about 4 minutes..

they were whiter definitely.. a couple were too light in spite of my care. - i have no idea if the ivory was damaged since i gave them to the guy i sold my piano to.

love and peace, Õun (apple in Estonian)

Dear Jazzpianoguy-

I have used this method on several different makes and models through the years with the last being a Hamburg D . No ill effects several years later. Your mileage may vary.

Regards-

David

I have seen 100 year old celluloid keytops that look perfectly fine. Good quality plastic will definitely outlast ivory.

A 30 000 Year Old Ivory Horse Sculpture from South Germany

By

Maximilian O. Baldia











What is among the oldest Stone Age Art was reported July 28, 2000 in an invitation to this year’s press conference by the excavators in South Germany. The press release was sent out by the German Internet information service Informationsdienst Wissenschaft (idw) in cooperation with the Eberhard-Karls-University in Tübingen.

The report states that Prof. Nicholas Conard and coworkers found a 30 000 year old ivory horse sculpture in the “Hohle Fels” cave. In addition to the sculpture two years of excavations have yielded nearly 10 000 artifacts, consisting mainly of animal bones and stone artifacts, but also include organic material, such as staffs of reindeer antler, adornments, etc.

Can plastic trump that?
