We dismantled a very old upright piano and kept the keys with idea of making jewelry or something but do not have time or energy. I am not 100% sure what they are made of but it is likely since the piano was about 100 years old the white keys were covered with ivory not sure what wood the black keys are... BUT ivory has an international sale ban on it so the Center for Creative Reuse *cannot* take them but I hate to chuck it in the garbage. Does someone want them? They are free and I'd love to see them repurposed in some way. Nicole carlin5707@gmail.com
