White Mulberry

White Mulberry is the wood of Morus alba, a small to medium deciduous tree native to China and long naturalized across Europe and Western Asia, where it was spread for centuries as the food plant of the silkworm. It is a short-boled, often crooked tree that rarely yields large clear logs, so its timber tends to reach the market as smaller boards, turning blanks, and craft stock rather than as commodity lumber.

At a glance the wood is fine and even-grained with subtle growth rings. Freshly cut and in pale sapwood-rich stock it reads cream to light tan — as on this sample — while the mature heartwood can develop a warmer golden-brown to russet tone that deepens with light exposure. It is dense, hard, and tough for a fruitwood, and its combination of workable texture and occasional wavy or rippled figure makes it a favorite of turners, carvers, and small-scale furniture makers.

Sapwood is pale — cream to light tan or pale yellow — and is often broad on this small-diameter tree, so many sawn pieces read light overall, matching this sample's pale cream to light-tan color and fine, even grain with subtle growth rings. The heartwood is more distinctive: a golden yellow to warm olive-brown that oxidizes toward a russet or reddish-brown with age and UV exposure. The grain is typically straight but can be wavy or interlocked, and figured stock shows an attractive ripple or curl. Texture is fine and even with a natural, satiny luster; the wood is ring-porous, so annual rings are visible as bands.

Mulberry is a dense, hard, tough wood — Janka hardness is roughly 1,540 lbf, placing it in the hard range, comparable to hard maple or white oak. It is strong, stiff, and shock-resistant relative to its modest tree size.

Natural durability is good: the heartwood is rated durable to very durable with reasonable resistance to decay, which historically made it valued for fence posts, stakes, and outdoor uses. The pale sapwood, however, is not durable and is susceptible to insects, so decay resistance applies to the colored heartwood only.

Mulberry is above all a craftsman's and turner's wood. Bowls, spindles, boxes, tool handles, and small decorative turnings take advantage of its density, ripple figure, and warm color, and carvers value it for its fine, even texture. Figured and colorful boards are sought for small furniture, cabinetry accents, jewelry boxes, and inlay or banding.

Because the tree is small and often gnarled, it seldom appears as flooring or structural timber, but its durable heartwood has long served for fence posts, stakes, gate parts, and other ground-contact work in its native range. It is also used for sporting goods and handles where toughness matters, and historically for cooperage, wheel and cart parts, and boat framing in regions where it was plentiful. In East Asia the wood and roots have additional traditional and instrument-making uses.

Mulberry works well with both hand and machine tools despite its hardness; sharp, well-set cutters give clean results, though wavy or interlocked grain can tear out during planing, so a reduced cutting angle and light finishing cuts help. It turns and carves excellently, holding crisp detail and taking a fine surface straight from the tool. It can be somewhat prone to checking and movement during drying, so slow, careful seasoning of blanks pays off.

The wood glues and finishes well, developing a warm glow under oil or clear finishes; because the golden and russet heartwood tones can shift and darken with light, makers sometimes account for that when matching colors. It holds screws and nails adequately but, like most dense hardwoods, benefits from pilot holes near edges.

On safety, mulberry is not a widely reported sensitizer, but as with any fine hardwood dust it can cause respiratory and skin irritation in some workers, so effective dust extraction and a respirator are sensible. Morus alba is not listed on CITES and is not an endangered timber.

White Mulberry is not a commercial timber and is essentially never stocked as dimensional lumber. It reaches woodworkers as turning blanks, craft billets, and occasional small boards — usually from urban, orchard, or silk-culture trees, salvaged wood, or hobbyist sawyers. Availability is sporadic and local rather than through mainstream suppliers.

Because it is sold as specialty and figured craft stock, pricing is set by piece and by figure rather than by board foot: plain pale pieces are modest, while well-colored or rippled heartwood blanks command a premium among turners. Expect to source it from specialty turning-blank dealers, arborists, or small mills rather than lumberyards.

Sustainability is not a concern for this species: Morus alba is abundant, fast-growing, widely naturalized, and often considered weedy or invasive outside its native range, so most mulberry wood is a byproduct of tree removal. It carries no CITES listing and no endangered status, and salvaged urban trees make it an easy responsible choice.
