Dag

Hmmmmmm, Joe graphite is carbon not metal.  I don't personally use
graphite but if I did it would still be carbon.  :-)

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.)
