Danish oil is a advertising name for an oil varnish mix. The average is about 1/3 each oil(usually linseed),varnish(usually polyurethane varnish) and mineral spirits. There are no standards and the percentages vary a great deal,Watco is almost 50% solvent. If you are just interested in popping the grain without using dye and/or shellac, flood the surface with linseed oil let it soak for 20-30 minutes wipe off excess and buff the surface well. Let it cure for a couple days and apply a top coat. What protection danish oil offers is from the very thin varnish component.
