safe wood finish

http://www.finewoodworking.com/how-to/article/food-safe-finishes.aspx

Pure tung oil. Extracted from the nut of the china wood tree. Used as a base in many blended finishes. Available from catalogs and hardware stores. Difficult to apply, requires many coats, good water-resistance.
Raw linseed oil.Pressed from flax seeds. Not to be confused with boiled linseed, which contains metallic driers. Listed as a food additive by the Food and Drug Administration (FDA). Very long curing time, good looks, low water-resistance, frequent reapplication.
Mineral oil.Although derived from petroleum, it is colorless, odorless, tasteless and entirely inert. Sold as a laxative in drug stores and as a wood finish in hardware and kitchen-supply stores. Simple to apply, low waterresistance, frequent reapplication.
Walnut oil.Pressed from the nuts of the walnut tree. Sold as a salad oil in health food stores and in large grocery stores. Walnut oil dries and won't go rancid. Easy to apply, frequent reapplication.
Beeswax.The work of the honey bee. Can be mixed with an oil to create a better-smelling, slightly more waterrepellent finish. Sold in woodworking and turning catalogs.
Carnauba wax.Derived from the Brazilian palm tree. Harder than beeswax and more water-resistant. Can be used straight on woodenware as a light protective coating or a topcoat polish. Sold in woodworking and turning catalogs.
Shellac.A secretion from the lac bug. Harvested in India. Super blond shellac in flake form is the most waterresistant variety. A film-forming finish. Sold in woodworking catalogs and hardware and art supply stores.
