Mastering a rercord in the days of 78's called for making the first 
"impression" (take one) on a platter of hardened wax which was engraved 
by the recoding stylus.
This wax cutting was then used in a process called "lost wax" copying to 
make a metallic master which in turn became the transfer plate to the 
(early) shellac, and later vynal. It was much like a printing plate used 
to print money, an engraved "plate" to create a duplicate of the 
original recording on wax. This is why there are still references to 
"Wax" used in relation to records. 
For years, a furniture refinisher friend used to ask me to look for old 
shellac records of any kind for him, which he would then crush and 
delute in shellac thinner to make a black shallac used in refurnishing 
old furniture pieces that has been orignally finished in  a black 
laquer/shellac base. I always brought him old lieder type records of 
god-awful foriegn singers who hurt my ears.
