Carob

Carob is the wood of Ceratonia siliqua, a small to medium evergreen tree of the legume family (Fabaceae) native to the Mediterranean region — Southern Europe, North Africa, and the Near East. The tree is far better known for its long, sweet seed pods, harvested as a chocolate substitute and animal feed, than for its timber, and it is grown chiefly as an orchard and shade tree. Wood therefore reaches the market only as a by-product of orchard clearing, pruning, and windfall, in short and often knotty or twisted lengths.

At a glance carob is a dense, hard, fine-grained hardwood in warm tan to light-brown tones. On our sample the grain reads fine with visible growth rings and a radiating pattern from the pith. Because the tree is short-boled and branchy, boards are small and figure is often busy, which suits it to turning and small craft work rather than long, clear cabinet stock.

The wood runs tan to light brown, sometimes with a pinkish or reddish cast in the heartwood, over a paler, less sharply defined sapwood; color deepens somewhat with age and exposure. The grain is fine and fairly close, frequently irregular or wavy because of the tree's twisted, branching habit, and cut surfaces show the visible growth rings and radiating rays seen on our sample. Texture is fine and even with a moderate natural luster.

Carob is a genuinely dense, hard wood — Janka hardness is roughly 1,700 lbf, placing it in the hard range alongside hard maple and hickory and well above walnut or cherry. It is heavy, stiff, and strong for its size, though the short, knotty logs limit how much of that strength can be put to structural use.

Natural durability is moderate: the heartwood has fair resistance to decay but is not a reliable choice for ground contact or exposed exterior use, and the sapwood is prone to insect attack. Like many orchard hardwoods, freshly felled carob is prone to checking and distortion, so it must be dried slowly and carefully.

Carob is a small-scale specialty and craft timber rather than a commercial one. Its density, fine grain, and warm color make it a favorite among woodturners for bowls, spindles, boxes, and other small turned objects, where its busy figure and occasional burl are assets rather than drawbacks.

Beyond turning it is used for carving, knife and tool handles, walking sticks and canes, inlay and marquetry accents, and small decorative and household items. Where longer clear pieces can be recovered it serves for small furniture parts and millwork. Because it is dense and slow-growing, it also burns hot and clean and is valued locally as firewood and for charcoal — often the main fate of orchard prunings and cleared trees.

Carob works much like other dense fruit- and orchard-woods: it is firm under the tool and takes crisp detail, but its hardness and frequently irregular or interlocked grain can make hand-planing and machining harder work, with some tendency to tear out around knots and wavy figure. Sharp, well-set tooling and reduced cutting angles give the cleanest surfaces, and pre-boring is wise before nailing or screwing near ends. It turns and carves very well, holding fine edges and detail.

The wood glues adequately and finishes to a fine, lustrous surface, taking oils and polishes readily thanks to its close grain; slow, careful drying is important to limit the checking and warp the species is prone to. No serious toxicity is specifically associated with carob wood, but as with any dense hardwood the fine dust can irritate the eyes, skin, and respiratory tract, so dust extraction and a respirator are sensible. The tree's pods are a common food, but the woody dust is best treated with the same caution as any hardwood.

Carob wood is scarce in commercial terms and is essentially never stocked as dimensioned lumber. It appears mostly as turning blanks, small craft pieces, and slabs offered by specialty dealers, turners' suppliers, and local sawyers in Mediterranean countries, salvaged from orchard clearing and prunings. Prices are set by scarcity and by the small, often figured pieces available rather than by any board-foot commodity rate, so expect it to be sold as an uncommon specialty wood.

The species is not listed under CITES and is not considered threatened — it is a widely cultivated orchard tree across the Mediterranean and beyond. Because supply comes from orchard by-product rather than forest harvest, using carob wood carries little sustainability concern; the main limitation is simply availability and the small size of the pieces.
