Gusana Ibibumbano Byamenetse ukoresheje Irangi rya Laki na Zahabu (Kintsugi) — Ubugeni bwo Guhuza na Zahabu

Sukura neza impande zose zamenetse ukoresheje amazi y'akazuyazi, maze ubireke byume neza. Kuraho kole ishaje yose yasizwe n'igihe wagerageje gusana mbere, ukoresheje amavuta ya kamfure cyangwa aseton. Banza uhuze ibice bikiri byumye kugira ngo wumve uko bijyana, maze ufotore uko biteranye ngo bizakubere urugero. Kintsugi ikora neza cyane ku bice byamenetse neza bihura bikwiranye. Niba hari uduce duto twabuze, tuzuzuzwa n'ivangiro rya laki mu ntambwe ikurikiraho. Ambara uturindantoki twa nitrile igihe cyose ukora: urushi rudatunganyije rufite urushiol, ikinyabutabire kimwe n'icyo mu kimera cyitwa poison ivy, kandi rutera abantu benshi indwara ikomeye y'uruhu iterwa no gukoraho. Korera ahantu hinjira umwuka mwiza.

Kora ikomatanya gakondo ryitwa mugi-urushi: kanda ifu y'ingano isanzwe n'amazi make kugeza ibaye irobe rikomeye, hanyuma uvangemo urushi rudatunganyije (ki-urushi) — hafi ingano zingana z'urushi n'ifu — kugeza ivangiro rigumana ishusho ryaryo ntirisandare. Siga ivangiro ku ruhande rumwe rwa buri hantu hamenetse ukoresheje akuma gato ko gusiga, hanyuma ukande ibice ubihuze cyane. Hanagura ibirenga bisohoka, ariko ntuhangayikishwe no kubinoza — urwego rwa nyuma rwa zahabu ruzapfuka aho byahurijwe. Fatisha ibice byahujwe ukoresheje igipapuro gifatisha cyangwa imigozi y'ibirastike. Shyira igikoresho cyateranyijwe mu gasanduku k'ubuhehere (igikoresho gifunze kirimo igitambaro gitose, kigumishwa mu buhehere bwinshi; akabati gakondo kabigenewe kitwa furo) mu gihe cy'ibyumweru 1-2. Urushi ntirukomera kubera kuma: rukomera binyuze mu kwivanga buhoro n'umwuka wa ogisijeni bibaho gusa mu mwuka ushyushye kandi urimo ubuhehere, bityo mu cyumba cyumutse rugumana ubworoherane.

Ikomatanya rimaze gukomera (ibyumweru 1-2), suzuma aho byahurijwe. Uzuza imyanya, uduce twabuze cyangwa ahantu hacukutse ukoresheje sabi-urushi — urushi rudatunganyije ruvanze na tonoko (ifu y'amabuye yoroshye cyane, mu buryo gakondo ivuye ku rutare rw'ibumba rwangijwe n'ibihe cyangwa ku gukata amabuye yo gutyaza) n'amazi make — kugeza ubuso bungana n'ibibumbano bibukikije. Ahantu hanini habuze, siga ivangiro mu byiciro binanutse, kandi ureke buri cyiciro gikomerere mu gasanduku k'ubuhehere mbere yo kongeramo ikindi. Ibyiciro bibyibushye bikomera hejuru gusa ahasigaye hakaguma horoshye, amaherezo bigacika. Ibyuzujwe byose nibimara gukomera n'ubuso bukaringanira, kuba buhoro aho byahurijwe ukoresheje urupapuro rwo gukuba rukoreshwa n'amazi rwa grit 800, kugira ngo ubone ubuso buroroshye kandi buringaniye ku rwego rwa nyuma rwa zahabu.

Siga urwego runanutse rw'urushi ku mirongo yasanwe ukoresheje uburoso bworoshye — mu buryo gakondo ni bengara-urushi, isizwe ibara na oxide y'icyuma itukura, iha zahabu ishingiro rishyushye. Kora witonze kugira ngo laki igume aho byahurijwe gusa — urushi rwakomeye rugorana kuvanwa ku buso bwasizwe. Laki imaze gufata gato (igihe cyo gutegereza giterwa n'ubushyuhe n'ubuhehere, bityo ubigerageze ku mpera y'umurongo), minjira ifu ya zahabu kuri laki ukoresheje uburoso bworoshye cyangwa ipamba. Zahabu ifata kuri laki ifata, igatemba ku hantu humutse. Koresha ifu ya zahabu itunganye ku bintu bizakora ku biribwa, cyangwa ifu y'umuringa nk'igisimbura cy'umutako kitemewe ku biribwa. Subiza igikoresho mu gasanduku k'ubuhehere kugira ngo gikomere bwa nyuma mu gihe cy'ibyumweru 1-2.

Nyuma yo gukomera bwa nyuma, kuba buhoro imirongo ya zahabu ukoresheje igitambaro cyoroshye cyangwa igikoresho cyo gusiga gikozwe mu ibuye rya agate, kugira ngo ifu ya zahabu yegerane maze irabagirane. Ifu ya zahabu irenga ku buso buyikikije ishobora guhanagurwa n'igitambaro gitoshejwe amavuta ya kamfure. Kugira ngo bikomere kurushaho kandi birabagirane, siga urundi rwego runanutse cyane rw'urushi rubonerana hejuru ya zahabu, maze ureke rukomere mu kindi cyumweru. Iyo byamaze gukomera neza, isanwa ryakozwe n'urushi kamere na zahabu itunganye ntirinjirwamo n'amazi kandi rirakomeye ku ikoreshwa risanzwe, kandi urushi rwakomeye ni ikintu kimwe n'ibikombe gakondo byo kuriramo bisizwe laki. Imirongo ya zahabu ni iy'igihe cyose kandi ntigenda iyo byogejwe. Kintsugi ifitanye isano na wabi-sabi, kwakira ibifite inenge n'ibituzuye: kumeneka no gusanwa bifatwa nk'igice cy'amateka y'ikintu, si ikintu cyo guhisha.
