Medienos išvaizda
Kaip atrodo
Pale pinkish-tan to warm salmon, deepening to a soft russet with age and light. Texture is dense, even, and almost poreless under the hand. Figure is quiet, gentle ribbon and the occasional fine fleck, which is exactly why carvers and marquetry workers prize it. The grain doesn't fight you, and detail holds crisply.
- Pale pinkish-tan when fresh off the saw
- Warm salmon to soft russet with age
- Steamed pear takes a uniform pinkish hue
- Stains evenly to deep black for ebonised work
- Subtle ribbon figure; rarely dramatic
- Mild UV warming, no harsh colour shift
- Labai smulki, tolygi tekstūra; subtilus raštas.
Apdirbimas
Apdirbimas
Carves, turns, and planes superbly, this is a benchmark wood for fine work. Cuts cleanly across the grain without tearing, holds knife-edge detail, and turns to crisp profiles. Sands to a near-polished surface straight off the tool. Glues and screws well. Steam bending is moderate. The low stiffness helps it bend, but it can compress unevenly, so test on offcuts.
Apdaila
Sands to a glass-smooth surface, one of the cleanest finishes you can pull off any European hardwood. Takes oil, wax, and shellac evenly with no blotching. Steaming produces the uniform pinkish tone historically used to imitate ebony when stained black (the piano-key trick). For natural finishes, hard-wax oil holds the warm tone; lacquer can flatten it. Expect mild warming in UV.
Džiovinimas
Honest tradeoff: tangential shrinkage is high (10.5–12%) against modest radial movement, so drying rate matters. Pear that's rushed will check, cup, and case-harden. Air-dry slowly under weight, then finish in a kiln on a gentle schedule. Once stable, it sits well indoors. Quartersawn or rift-sawn stock is the safer cut for wide panels.
Kiek mediena brinks ir trauksis?
Kintant oro drėgnumui, mediena skersai pločio brinksta ir traukiasi. Prieš projektuodami tvirtinimus apskaičiuokite numatomą sezoninį Paprastoji kriaušė stalviršio pokytį.

Didelis. Naudokite laikiklius arba gembes su pailgomis angomis, galuose palikite tarpus ir prieš surinkdami leiskite storlentei prisitaikyti prie aplinkos.

Food-contact safe, pear has a long tradition as kitchen utensil and treen wood. Not a commonly reported dust sensitiser. Standard shop dust extraction is enough.

What European Pear actually is#
Pyrus communis is the fine detail wood of Europe. Its texture is exceptionally close, even and dense, with essentially no visible grain direction, and at 7,420 N Janka it is one of the hardest species in this catalogue.
That pairing is unusual. Most woods that hold fine detail are soft, like lime. Most woods that are hard have pronounced grain that fights the tool, like oak. Pear is both hard and directionless, so carved detail is crisp and then survives being handled.
It is the traditional wood for woodcut printing blocks, recorders and wind instrument parts, drawing instruments, rulers, set squares and fine inlay, and all of those uses depend on the same property.
The orchard problem#
Pear is a fruit tree. It is grown for pears, and it reaches the timber market when an orchard tree comes to the end of its productive life.
The consequences are structural. Trunks are short and often irregular. Diameters are modest. Clean wide boards are genuinely scarce, and slab sized material is uncommon enough that finding it is the main constraint rather than affording it.
Expect narrow widths, short lengths, and a good deal of character.
Steamed and unsteamed

Why is pear so highly regarded for carving and instruments?
Its texture is exceptionally fine, even and dense, with essentially no visible grain direction, so it cuts equally well in any direction and holds very crisp detail. At 7,420 N Janka it is also hard, which means carved detail survives handling. That combination of fine texture and hardness is rare and is why pear has been the traditional wood for woodcuts, recorders, rulers and instrument parts.
What is steamed pear?
Pear that has been steamed during drying, which turns the pale pinkish wood a warm rose brown and evens the colour. It is the standard European commercial treatment and the colour most people associate with the species. Unsteamed pear is paler and more variable. The change is permanent.
Why are pear boards so small?
It is an orchard tree, grown for fruit and felled at the end of its productive life rather than for timber. Trunks are short, often irregular, and rarely large. Wide clean pear is genuinely scarce and priced accordingly, and slab sized material is uncommon.
