Changes in the art of wood-finishing has come about through the rapid progress in the development of quick-drying, very permanent, nitrocellulose lacquers which are new finishes derived from the realm of magic and mystery Present-day lacquers contain varnish-gums in addition to nitrocellulose, and dry so quickly that they are practically dust-proof; yet they set slowly enough so that they can be applied with little training by use of either a brush or a spray-gun
