Hard Wood and Soft Wood--Closeness of Grain Desirable--Advantages of Pine and English Oak.
The woods suitable for carving are very various; but we shall confine our attention to those in common use. Of the softer woods, those which are most easily procured and most adaptable to modern uses are yellow pine, Bass wood, Kauri pine, and Lime. These are all good woods for the carver; but we need not at present look for any better qualities than we shall find in a good piece of yellow pine, free from knots or shakes.
The following woods may be considered as having an intermediate place between soft and hard: Sycamore, Beech, and Holly. They are light-colored woods, and Very useful for broad shallow work.
_English Oak._--Of the hard woods in common use, the principal kinds are Oak, Walnut, and occasionally Mahogany. Of oak, the English variety is by far the best for the carver, being close in the grain and very hard. It is beyond all others the carvers' wood, and was invariably used by them in this country during the robust period of medieval craftsmanship. It offers to the carver an invigorating resistance to his tools, and its character determines to a great extent that of the work put upon it. It takes in finishing a very beautiful surface, when skilfully handled--and this tempts the carver to make the most of his opportunities by adapting his execution to its virtues. Other oaks, such as Austrian and American, are often used, but they do not offer quite the same tempting opportunity to the carver. They are, by nature, quicker-growing trees, and are, consequently, more open in the grain. They have tough, sinewy fibers, alternating with softer material. They rarely take the same degree of finish as the English oak, but remain somewhat dull in texture. Good pieces for carving may be got, but they must be picked out from a quantity of stuff. Chestnut is sometimes used as a substitute for oak, but it is better fitted for large-scaled work where fineness of detail is not of so much importance.
_Italian Walnut._--This is a very fine-grained wood, of even texture. The Italian variety is the best for carving: it cuts with something of the firmness of English oak, and is capable of receiving even more finish of surface in small details. It is admirably suited for fine work in low relief. In choosing this wood for carving, the hardest and closest in grain should be picked, as it is by no means all of equal quality. It should be free from sap, which may be known by a light streak on the edges of the dark brown wood.
