Many thanks for all the replies. It’s definitely not going to be easy as I’d
hoped but looking at it I guess I knew that the color was trending more yellow
than would be expected from garnet shellac. It will take some experimentation
and I now have many things to try.
Richard mentioned "...patina, you might want to provide a bit of light wear and
damage”. That’s funny because on the other side of the table someone has gone
berzerk doing just that. It’s entirely cross-hatched in black. It might be
covering up graffiti, I don’t know yet. Getting rid of that will come before
finishing the rest. This table has suffered many fools. I’m next in line.
… and 78 records as a source of black shellac, that’s pretty cool.
