Naturally, the MANUFACTURING processes of very many things, can be very hazardous.  Think, for example, of the hazards presnt in an iron foundry!  Yet we are willing to use cast iron plates and steel music wire in pianos.  Think of the hazards present in a sawmill, yet we use wood.

Teflon itself, is inert at temperatures below 500F. I'd suggest putting space between yourself and any piano that is over 150F in temperature regardless of possibility of the use of teflon in servicing it. ;-) Andrew Anderson</pre> </blockquote> </body> </html>
