Gleditsia triacanthos
L-ħarrub tal-għasel huwa l-injam iebes ta’ Gleditsia triacanthos, siġra tal-Amerka ta’ Fuq b’qalb tal-injam kannella ħamrani u sapwood pallidu li jikkuntrasta magħha.
Agħfas tikketta għad-dettalji.
Bħalissa m’hemmx Honey locust. Dawn l-ispeċijiet jgħoddu għall-istess proġetti u għandhom biċċiet disponibbli.
Nibagħtulek email meta jaslu fallakki friski ta’ Honey locust għand KORENA. Kull biċċa hija unika, għalhekk avviż bikri jgħin.
Dehra tal-injam
Honey locust has conspicuous growth-ring figure and a moderately coarse texture. Heartwood runs from pink or light red to reddish brown, framed by broad pale sapwood. Grain can be straight or irregular. Choose a board for its actual colour, grain direction and sound usable area; the species name does not predict the figure of an individual slab.
Kif taħdem bih
Published descriptions differ: Purdue reports good machining, while the Alden wood fact sheet describes more difficult working but a smooth finish. Start with sharp tools and trial cuts on the actual board. A 2024 University of Ljubljana study included honey locust and found useful bonds with PVAc and one-component polyurethane; adhesive choice and moisture exposure mattered. This supports trial gluing, not a universal five-point operation score.
KORENA workshop guidance: compare finish samples on an offcut containing both heartwood and sapwood. Decide whether to retain the visible pore texture or use a compatible grain filler for a smoother surface. Follow the finish maker’s sanding and application instructions, and compare the fully cured sample in the light where the furniture will stand. A species-specific ranking of oils, waxes and lacquers has not been established.
Total shrinkage from green to oven-dry is 4.2% radial, 6.6% tangential and 10.8% volumetric (USDA). The tangential/radial ratio is approximately 1.57. These are reference totals, not the movement expected between seasons. Workshop guidance: measure the actual slab’s moisture, allow it to equilibrate with the intended environment, and use attachments that permit cross-grain movement. No universal drying time or thick-slab kiln schedule is specified here.
L-injam jintefaħ u jiċkien tul il-wisa’ hekk kif l-arja ssir aktar jew inqas umda. Stima l-moviment staġjonali ta’ wiċċ ta’ Honey locust qabel tiddisinja t-twaħħil.

Control dust from sawing and sanding with extraction at the tool and suitable respiratory protection where required. HSE identifies wood dust as a health hazard; a missing species-specific sensitisation report does not mean the dust is harmless. Food-contact suitability has not been established for this species entry and should not be inferred from a clear finish.
Gleditsia triacanthos is native to west-central and eastern USA and parts of northeastern Mexico. Kew records it as introduced in Bulgaria. A particular slab’s harvest origin must come from its own provenance record.
IUCN lists Gleditsia triacanthos as Least Concern in its 2018 global assessment, checked on 2 October 2026. This describes the species, not the legality or sustainability of an individual lot. Kew records introduced occurrence in Bulgaria. Confirm harvest location and chain of custody from the board’s documents; neither North American botanical origin nor occurrence in Europe proves where the board was grown.
Il-ħarrub tal-għasel huwa Gleditsia triacanthos, is-siġra msejħa гледичия bil-Bulgaru. L-aktar karatteristika viżiva qawwija tagħha hija l-kuntrast bejn il-heartwood sħun u s-sapwood pallidu. Il-grain għandu xejra ċara ta’ ċrieki tat-tkabbir aktar milli tessut uniformi u fin. Huwa għażla għal għamara fejn l-injam innifsu għandu jibqa’ viżibbli, b’kull board evalwat fuq il-merti tiegħu stess.
Tħawwadx dan mal-black locust, Robinia pseudoacacia. Isem komuni maqsum ma jagħmilx iż-żewġ injamijiet interkambjabbli. Id-deskrizzjoni botanika ta’ NC State tgħin tistabbilixxi l-identità; l-isem xjentifiku għandu jkompli jseħħ fir-rekord tal-fornitur.
Il-profil tal-honey locust ta’ Purdue jiddeskrivi injam ring-porous b’xejra ta’ grain simili għall-ballut u jinnota li siġar ta’ kwalità ta’ sawlog mhumiex abbundanti fil-provvista bl-ingrossa. Id-disponibbiltà ta’ slab attraenti waħda għalhekk ma twiegħedx boards li jaqblu għal estensjoni aktar tard.
Gwida tax-xiri ta’ KORENA: eżamina ż-żewġ uċuħ u t-truf. Immarka l-parti li tibqa’ wara l-flattening, it-trimming u t-tneħħija ta’ materjal mhux sod. Ivverifika li t-tarf pallidu hu sapwood sod aktar milli tassumi li kull żona ċara hija difett. Itlob moisture imkejjel u storja tat-tnixxif, u kkonferma jekk il-thickness ikkwotatx hu rough-sawn jew finished. Dawn il-kontrolli huma aktar importanti minn deskrizzjoni ġenerika tal-ispeċi meta tkun qed tippjana top wiesa’.
Il-katalgu juża density tipika ta’ 750 kg/m³ f’12% moisture content, ikkonvertita minn 46.8 lb/ft³ ta’ Purdue. Għall-ippjanar, immultiplika l-volum finished b’din id-density: top rettangolari li jkejjel 2.0 × 0.9 × 0.04 m huwa madwar 54 kg qabel is-saqajn jew l-hardware. Din hija stima kkalkulata; live edges, vojtijiet u moisture ibiddlu r-riżultat.
Il-USDA Wood Handbook jagħti valuri ta’ referenza għal dry clear-wood ta’ 7,000 N side hardness, 101 MPa bending strength, 11.2 GPa stiffness u 51.7 MPa compression parallel to grain. Dawn jiddeskrivu materjal tat-test, mhux il-load rating ta’ mejda finished jew grad strutturali. Knots, checks, dimensjonijiet u d-disinn tal-ġonot jibqgħu jiddeterminaw il-biċċa vera.
M’hemm l-ebda bażi soda hawn biex jiġu kkupjati s-scores ta’ operazzjoni tal-black walnut. Purdue jiddeskrivi machining tajjeb, filwaqt li l-fact sheet ta’ Alden jiddeskrivi xogħol aktar iebes b’wiċċ finished lixx. Id-direzzjoni tal-grain u l-stock attwali jistħoqqilhom trial cut qabel ma tikkonferma l-wiċċ viżibbli.
Hemm riċerka diretta dwar il-gluing. Kariž u l-kollegi (2024) inkludew il-honey locust f’testijiet ta’ adhesives PVAc u one-component polyurethane. L-istudju jappoġġa l-potenzjal tiegħu għal bonded woodworking, bir-riżultati affettwati mill-kondizzjonament u l-għażla tal-adhesive. Ma jikkwalifikax kull glue kummerċjali għal kull espożizzjoni. Uża uċuħ tal-ġonta nodfa u li jaqblu tajjeb, u segwi l-istruzzjonijiet tal-adhesive magħżul; trial joints jiswew għall-stock mhux familjari.
L-USDA jirrapporta total green-to-oven-dry shrinkage ta’ 4.2% radial, 6.6% tangential u 10.8% volumetric. Tangential shrinkage hija madwar 1.57 darbiet radial shrinkage. Dawn il-valuri huma utli għat-tqabbil, iżda li tapplika 6.6% direttament bħala allowance staġjonali għal tabletop ikun qari ħażin tal-kejl.
Gwida tal-workshop ta’ KORENA: irreġistra l-moisture qabel is-sizing finali, ħalli l-materjal jaġġusta għall-ambjent maħsub u ħalli movement cross-grain fid-disinn tat-twaħħil. Skeda ta’ drying għal lumber ordinarju mhijiex awtomatikament adattata għal slab oħxon. M’hemm l-ebda perjodu fiss ta’ acclimatisation li jieħu post il-kejl tal-injam.
Ibda b’offcut li jinkludi l-kuluri li biħsiebek iżżomm. Qabbel il-finish kompletament cured, mhux biss id-dehra tiegħu meta jkun imxarrab. Iddeċiedi jekk it-texture tal-pori hijiex parti mid-disinn jew jekk hux mixtieq filler kompatibbli, u uża s-sekwenza ta’ preparazzjoni tal-manifattur tal-coating.
Bħala suġġerimenti tad-disinn, il-black walnut jista’ jipprovdi kuntrast skur u l-European ash sieħeb eħfef. Dawn huma tqabbil viżiv, mhux pretensjonijiet ta’ moviment jew saħħa identiċi. Uża komponenti separati jew joinery li takkomoda l-imġiba tagħhom aktar milli tittratta injam differenti bħala dimensjonalment identiku.
Għamara, flooring u xogħol ta’ ġewwa huma użi dokumentati. Tabletops, desks u cabinet fronts huma modi prattiċi biex jintwera l-grain, bil-kondizzjoni li l-stock u l-kostruzzjoni jkunu adattati għax-xogħol. Ikkonferma l-klassifikazzjoni u r-rekwiżiti tal-finish għall-flooring aktar milli tittratta kwalunkwe slab dekorattiv bħala flooring stock.
L-użu storiku bħala post ma jikkostitwixxix klassi moderna ta’ durability. Is-sorsi jiddeskrivu r-reżistenza għat-taħsir b’modi differenti, għalhekk din l-entrata ma twiegħedx servizz fit-tul mhux ittrattat fuq barra jew f’kuntatt mal-art.
Il-gwida tal-HSE tapplika għall-periklu tat-trab: aqbad it-trab fil-magna, uża protezzjoni respiratorja xierqa fejn meħtieġ u naddaf b’vacuum industrijali adattat. In-nuqqas ta’ evalwazzjoni ta’ sensitizzazzjoni speċifika għall-honey locust mhuwiex prova li t-trab ma jagħmilx ħsara. Pretensjoni dwar adattabbiltà għall-kuntatt mal-ikel ma ġietx stabbilita għal din l-entrata.
L-evalwazzjoni globali tal-2018 tal-IUCN telenka l-ispeċi bħala Least Concern. Kew tirreġistraha bħala introdotta fil-Bulgarija. L-ebda stqarrija ma tiċċertifika lot ta’ injam partikolari. Itlob il-post attwali tal-ħsad u l-chain of custody, u uża dawk ir-rekords meta tevalwa x-xiri.
Mistoqsijiet tax-xerrejja
No. Honey locust is Gleditsia triacanthos; black locust is Robinia pseudoacacia. Their similar common names are not a basis for transferring durability or woodworking claims between them.
Furniture is an established use, and its pronounced grain can suit a substantial tabletop. Inspect the actual slab for soundness, moisture and usable dimensions, and design its base and fixings for weight and seasonal movement.
The reference density is about 750 kg/m³ at 12% moisture content. A rectangular 2.0 × 0.9 × 0.04 m top would contain 0.072 m³ and weigh approximately 54 kg before hardware. Live edges, voids and actual moisture change that estimate.
A 2024 study tested honey locust with PVAc and one-component polyurethane adhesives and found useful bonding performance. Results depended on adhesive and conditioning. Test your stock and follow the adhesive maker’s preparation, pressure and curing instructions.
Published descriptions of decay resistance differ, and an EN 350 durability class has not been verified here. Historical use for posts is not a guarantee of service life. Choose exterior material against the actual exposure and applicable product requirements.
No. The radial 4.2%, tangential 6.6% and volumetric 10.8% figures describe green-to-oven-dry shrinkage. Seasonal movement depends on the moisture change, board width and grain orientation.
No. Thornless cultivated forms exist. Absence of thorns alone does not rule out honey locust; check leaves, pods and the recorded botanical identity.
No. The species is native to North America but has been introduced elsewhere, including Bulgaria. The harvest location must come from the particular board’s provenance record.
