    Definition

    Shellac

    A finish made from lac resin dissolved in alcohol. Dries fast, repairs easily, sold or mixed in cuts from 1-lb to 3-lb. Excellent as a sealer or as a finish in its own right.

    Blotch

    Uneven stain absorption caused by varying grain density within a board. Common in cherry, pine, birch, alder, and poplar. Prevented with pre-conditioner, dye, or gel stain.
