_Oil or Copal Varnishes._ The old Cremona varnish once used for violins is supposed to have had amber (Greek, electron) as its base.
It was a fossilized coniferous resin found on the shore of the Baltic Sea.

The art of making it is said to be lost, probably because of the difficulty and danger of melting it, for this can be done only in oil on account of the danger of ignition.

Hence its use has been abandoned.
Perhaps the most beautiful of all varnishes is lacquer, much used in China and Japan.

It is made from the juice of the lacquer tree, (_Rhus vernicifera_) which is tapped during the summer months.
