Hmmmmmm, Joe graphite is carbon not metal.  I don’t personally use graphite but if I did it would still be carbon.  J

Julia asked: "Greetings, 
 
Just curious, can Acheson dag after it is dried up, be re ground and 
liquified again? If so, what would the solvent/medium be? If it cannot be re 
liquified, then if it is ground into a fine powder, can it be used as a 
graphite lube for pedal rods and such, where smeared black stuff isnt a matter?
 
Thanks in advance,"
 
 
Julia,
The solvent for Dag is Isopropyl Alcohol. Yes, it can be "reconstituted". However, I do not recommend it for lubing "pedal rods and such..." It's fine for coating bridge tops, if you must, but...Think about it: Graphite is a natural metal/rock. When powdered, it's still metal. If you apply it to other metal it will coat, (somewhat), but you've still got metal against metal. In a friction situation you WILL GET SQUEAKS when you use this stuff. Trapwork, generally works, noise free, if you use absolutely nothing. However, there are exceptions.<G> In the exceptional cases, a lube that is better suited for such is VJ Lube or the more modern version that uses Teflon. In my opinion, Graphite, in any form, has NO PLACE in pianos! (There are better alternatives.)
