I watched a turning video in which the turner used multiple coats of tung oil to get a fairly shiny finish on his bowl. He was going for a glass-like finish by adding additional coats of what he called "shine juice", which is nothing more than the old three equal parts resin, oil and thinner. (He used shellac, BLO, and alcohol.) And he did get a beautiful shiny finish for his considerable effort. None of this is really new to me-- except the long "drying" times , namely overnight, for each coat of tung oil. So I thought I would give it a try. But I used boiled linseed oil instead of tung oil for these initial coats of oil. The results were good looking-- kind of a rich dark brown color on this particular wood-- but it's not even slightly shiny; it's fairly dull. Is  this dullish result due to using BLO instead of tung oil? I can't think of any other reason. What do you think?
