In reply to davidbeynon:
Linseed oil will age, darken and aquire a shiny lustre over time and with use... More coats will help, but it won't aquire the same glossy sheen as a varnish, or French polish.
If you're looking for good drying times and 'build' then Double Boiled Linseed oil is better; normally boiled linseed oil is just raw linseed with a transition metal catalyst to speed up polymerisation these days, Double Boiled usually refers to the traditional heat treated oil which is already oligomerised (part polymerised) with better characteristics in terms of durability and coat formation.
Linseed Based Varnish is great stuff too, easy to make too, melt rosin and a little beeswax in a bowl over boiling water, then add linseed oil of approx the same weight as the rosin, stir until the rosin is fully dissolved in the oil, cool and thin to desired consistency with turpentine, extremely durable and takes a fantastic gloss when polished.
