oil varnish

Did they use oil varnish, our successors would at all events reap the benefit, if not ourselves.

Then stir in five ounces of glycerine, ten ounces of turpentine, and five ounces of linseed oil varnish.

But to what oil varnish is not my present purpose; why should I seek to close the door on research and on experiment?

Therefore, I shall draw your attention to the use of oil varnish, utterly discarding that of spirit.

When this varnish is dry, two or three coats of copal, or oil varnish are applied, at intervals of two days.
