At the risk of sounding dumb, I have a question about food-safe finishing (yes, again). I've seen several posts that talk about BLO plus Mineral Spirits to bring out the color in a piece. Then I've seen posts saying that Mineral Oil is food safe.
Is BLO a mineral oil?
Is the BLO+MS followed by wax a food-safe finish?
How about BLO+MS followed by lacquer?
How about BLO+MS followed by shellac?
I've heard on this site that hard finishes like lacquer, shellac, or urethane are food-safe once they have lost their odor, but if you dig your fork into the salad bowl and scratch that hard surface, will the underlying BLO+MS be any issue? If so, what is an acceptable substitute?
