Izithombe Eziqoshwe Ngokwezifiso: Ukuguqula Izithombe Zibe Ubuciko Obungunaphakade
Izithombe ze-mosaic ezenziwe ngemabula ezenziwe ngokwezifiso zimelela enye yezindlela eziyinkimbinkimbi kakhulu zobuciko betshe lemvelo. Lezi zithombe zobuciko zihumusha izithombe zibe yizingcezu zamatshe ezihlala njalo zisebenzisa izinkulungwane zezingcezu zamatshe ezisikiwe ngazinye zemabula, i-granite, kanye nezingcezu zamatshe ezingabalulekile kangako. Ngokungafani nezithombe eziphrintiwe ezinyamalala phakathi namashumi eminyaka, izithombe ze-mosaic zemabula zihlala amakhulu eminyaka ngaphandle kokunakekelwa okuningi. Uhlobo lobuciko be-mosaic luye lwavela ezingcezwini zaseRoma lasendulo kuya ekufakweni kodonga lwezithombe zanamuhla ezingokoqobo ezibamba yonke imininingwane yokuvezwa nokukhanya.
Inqubo: Kusukela Esithombeni Kuya Ekubunjweni Kwetshe
Ukudala isithombe se-mosaic semabula esenziwe ngokwezifiso kuqala ngokufaka isithombe somthombo edijithali nokuhlaziya ukwakheka kombala waso. Izitudiyo ze-mosaic zobungcweti zisebenzisa isofthiwe ekhethekile ukudweba i-palette yombala wesithombe nezinhlobo zamatshe emvelo ezitholakalayo. Indawo ngayinye yombala esithombeni ihambisana nokukhethwa kwetshe elithile—imabula emhlophe yeCarrara ukuze kubonakale izinto ezivelele, imabula emnyama yeMarquina ukuze kubonakale izithunzi ezijulile, kanye nohlu lwamatshe anombala oluhlaza okwesibhakabhaka, ompunga, kanye nombala wemibala ephakathi nendawo kanye nemibala yesikhumba.
Isithombe sihlukaniswe ngesistimu yegridi lapho iseli ngalinye legridi limelela i-tessera yetshe elilodwa (ucezu ngalunye). Izilungiselelo zesisombululo zinquma usayizi we-tessera: izithombe zesisombululo esiphezulu zisebenzisa izingcezu ezincane ezilinganisa u-5×5mm kuya ku-10×10mm, kuyilapho ukwakheka kwesisombululo esiphansi kusebenzisa i-tesserae engu-15×15mm kuya ku-20×20mm. Isithombe semitha eli-1×1 esinqumweni esingu-10mm sidinga izingcezu zamatshe ezingaba ngu-10,000, ngasinye sinqunyiwe, sakhiwe, futhi sibekwe ngesandla.
Ukukhethwa Kwamatshe Ukuze Ubone Imininingwane Yobuso Nokubukeka Kwayo
Ukukhethwa kwamatshe emvelo kunquma ngqo ikhwalithi yesithombe. Ama-mosaic esithombe adinga amatshe anombala ofanayo kuzo zonke izinhlobo ngoba ukuhlukahluka kwethoni kuthinta ukunemba kokubonwa kobuso.Amaqoqo obuciko be-mosaic ye-marblengokuvamile ifaka izinhlobo zamatshe emvelo ezingu-40-60 ukuze kufezwe ububanzi bethoni obudingekayo ukuze kuthathwe izithombe ngendlela engokoqobo.
Amatshe acwebezelayo njengezinhlobo ezithile ze-onyx ne-alabaster ayaziswa ngokukhanya kwesikhumba ngoba adlulisela ukukhanya kancane, anikeze ukufudumala okufana nokuphila ezindaweni zobuso. Izinhlobo ze-granite emnyama zinikeza abamnyama abajulile nabazinzile abagcina umehluko phakathi namakhulu eminyaka.Isikhungo Samatshe Emveloihlinzeka ngezinhlelo zokuhlukanisa ukuze kube nokuvumelana kombala wamatshe emvelo okusetshenziswa yizitudiyo ze-mosaic lapho zichaza izinto zomsebenzi wesithombe.
Ubukhulu betshe bezithombe ze-mosaic buvame ukuba ngu-3–4mm, okuvumela i-mosaic ehlanganisiwe ukuthi ihlale ilula ngokwanele ukufakwa odongeni ngenkathi inikeza ukujula okwanele kokugcwala kombala. Izingcezu zamatshe ezincane zinamathela ku-mesh noma i-fiberglass backward ngesikhathi sokuhlanganiswa, kanti ingxenye yokugcina ifakwe ku-substrate eqinile ukuze ifakwe.
Amasu Okuhlanganisa Ngesandla Esithombeni Se-Mosaic
Ukuhlanganiswa kwezithombe ze-mosaic ngesandla kulandela indlela eqondile, lapho ucezu ngalunye lwetshe lusikwa lube yisimo bese lubekwa ngqo endaweni engemuva. Abadwebi be-mosaic abanekhono basebenzisa ama-nipper namasondo okusika ukuze bakhe i-tessera ngayinye ukuze ivumelane nendawo yayo ekhethiwe ekwakhiweni. Inqubo yokusika ilandela iphethini yegridi esungulwe ngesikhathi sokuhlaziywa kwesithombe kodwa ivumela ukulungiswa kobuciko lapho imininingwane emincane idinga izimo ezingajwayelekile.
Ubukhulu bobuso ezithombeni ze-mosaic budinga ukunakwa okukhethekile. Ubuchopho bomuntu buzwela kakhulu ekubunjweni kobuso—ngisho nokungalungi kahle kwesilinganiso samamilimitha endaweni yeso noma endaweni yomlomo kudala ukuphambuka okubonakalayo. Abadwebi be-mosaic abanolwazi baqala ukudweba izithombe ngamehlo nangomlomo, besungula amaphuzu okusekela ubuso ngaphambi kokugcwalisa izindawo ezizungezile.Ama-mosaic e-marble omlandobonisa indlela ochwepheshe abanolwazi abaveza ngayo izici ezibonakalayo ngokubeka amatshe ngendlela enembile.
Ukucatshangelwa Kosayizi kanye Nokuhwebelana Ngezixazululo
Usayizi wesithombe sikaMose uthinta ngqo kokubili umthelela obonakalayo kanye nokwenzeka kokwenziwa. Izithombe ezincane (0.5 × 0.5 amamitha) zidinga ama-tesserae amancane ngokulingana ukuze kugcinwe imininingwane kodwa kwandisa ubunzima bokukhiqiza ngoba ingxenye ngayinye yetshe ilula kakhulu ukuyiphatha. Izithombe ezinkulu (1.5 × 2.0 amamitha nangaphezulu) zivumela ukucaca okukhulu ngenkathi zigcina ukucaca okubonakalayo uma kubukwa kusuka ebangeni elijwayelekile legalari.
Ibanga lokubuka linquma usayizi we-tessera ofanele. Isithombe esihloselwe ukubukwa eduze (amamitha angu-1-2) sidinga osayizi be-tessera abangu-5-8mm ukuze sithole imininingwane ecacile. Izithombe ezibukwa kusukela kumamitha angu-3-5 zingasebenzisa i-tesserae engu-10-15mm enesisombululo esamukelekayo sokubona. Iminyuziyamu nezakhiwo zomphakathi ezisebenzisa izithombe ze-mosaic ngokuvamile zichaza isinqumo esisekelwe ebangeni lokubuka ukuze zilinganise izindleko nekhwalithi yokubuka.
Ama-medallions emabula asikwe nge-waterjet kanye namaphethini e-mosaicinikeza indlela ehambisanayo yemiklamo yejometri kanye nezinto ezisemngceleni ezihlela ukwakheka kwezithombe ezindaweni zokwakha.
Ukuqina Nokuphila Isikhathi Eside Kobuciko Bomosaic Betshe
Ukuqina kwezithombe ze-mosaic zemabula akunakuqhathaniswa nanoma iyiphi enye indlela yokudweba. Itshe lemvelo liyamelana nokuwohloka kwe-UV okubangela ukuthi izithombe ezinyathelisiwe ziphele, ligcina umbala uzinzile kuzo zonke izimo zokushisa eziphakeme, futhi limelana nomswakama kanye nokungcola kwemvelo. Izithombe ze-mosaic ezifakwe ezindaweni zangaphakathi ezivikelwe azidingi ukungenelela kokulondolozwa isikhathi esingaphezu kweminyaka eyi-100.
Ukulungiswa, uma ekugcineni kudingeka, kulula ngoba ama-tesserae onakele angasuswa futhi afakwe endaweni yawo ngaphandle kokuthinta izindawo ezizungezile.I-Getty Conservation Instituteishicilela iziqondiso zobuchwepheshe zokulondolozwa kwe-mosaic ezikhuluma ngokufanisa amatshe, ukuhambisana kwe-adhesive, kanye nezinqubo zokuhlanza ubuso bomsebenzi wobuciko be-mosaic wasendulo.
Ama-mosaic esithombe samatshe nawo amelana nokulimala ngokomzimba kangcono kunezinye izindlela zokubonisa isithombe. Ubuso betshe buyamelana nokuklwebheka, futhi indlela yokwakha i-mosaic isho ukuthi umonakalo wemithelela yendawo uthinta kuphela ama-tesserae ngqo kunobuso bonke besithombe. Lokhu kulungiswa kwenza ama-mosaic amatshe afanelekele izindawo zomphakathi ezinabantu abaningi lapho ezinye izinhlobo zesithombe zingadinga khona ukugqokwa noma izithiyo ezivikelayo.
Izicelo kanye Nokucatshangelwa Kokubekwa
Izithombe ze-mosaic zemabula ezenziwe ngokwezifiso zisetshenziswa ezindaweni ezahlukahlukene. Ikhomishini yendlunkulu yenkampani izithombe ze-mosaic zabasunguli kanye nabaphathi bezindawo zokufaka i-lobby unomphela. Iminyuziyamu kanye nezikhungo zamasiko zakha ukuhumusha kwe-mosaic kwezithombe zomlando zemibukiso yegalari unomphela. Abaqoqi abazimele bathumela izithombe ze-mosaic zomndeni zezindawo zokuhlala.
Ukukhanya kuthinta kakhulu ukubukeka kwesithombe se-mosaic. Ukukhanya okuqondiswayo nge-engeli engama-degree angu-30-45 ebusweni be-mosaic kudala amaphuzu avelele kanye nezithunzi ezithuthukisa ikhwalithi yesakhiwo setshe esinezinhlangothi ezintathu.Inhlangano Yobunjiniyela EkhanyisayoInikeza iziqondiso zokukhanyisa zemyuziyamu ezisebenza ekufakweni kwezithombe ze-mosaic, incoma amazinga okushisa ombala angu-3000–3500K ukuze itshe lemvelo libonise umbala wangempela ngokunembile.
Ukufakwa kwe-mosaic yemabula enkulukhombisa ikhono lobuchwepheshe lokukhiqiza kabusha izithombe eziyinkimbinkimbi ezindaweni ezibanzi besebenzisa amasu ayisisekelo afanayo nomsebenzi wesithombe, olinganiswe ngezilinganiso ezinkulu.
imibuzo ejwayelekile ukubuzwa
Kuthatha isikhathi esingakanani ukudala isithombe se-mosaic semabula esenziwe ngokwezifiso?
Isithombe esijwayelekile esingu-1×1 meter sidinga amasonto angu-8–12 kusukela ekuvunyelweni kwesithombe ngokukhetha izinto, ukusika amatshe, ukuhlanganisa ngesandla, kanye nokuqeda. Izithombe ezincane (0.5×0.5m) zidinga amasonto angu-4–6. Imisebenzi emikhulu (2×2m nangaphezulu) ingathatha amasonto angu-16–24 kuye ngokuthi imininingwane iyinkimbinkimbi kangakanani kanye nokutholakala kwamatshe.
Iyini isixazululo esincane sezici zobuso ezibonakalayo ku-mosaic?
Uma ubuka eduze ngaphansi kwamamitha amabili, ama-tesserae angu-5mm akhiqiza izici zobuso ezibonakalayo ezinemininingwane emihle. Uma unesinqumo esingu-8mm, izici zobuso ezinamandla zihlala zibonakala kodwa imininingwane yokubonakaliswa okucashile iyancipha. Ngaphansi kwesinqumo esingu-15mm, izithombe zilahlekelwa ukubonwa komuntu ngamunye futhi ziba nomuzwa kunokuba zibe nomuzwa.
Ingabe izithombe ze-mosaic zingafakwa ngaphandle?
Izithombe ze-mosaic zemabula zingafakwa ngaphandle ngokukhetha izinto ezifanele kanye nokuvala. I-tesserae ze-granite ne-quartzite ziyathandwa ekufakweni kwangaphandle ngenxa yokumelana nokuncibilika kweqhwa. Ukusetshenziswa kwe-sealer egcwele ukungena kanye ne-grout engamelana ne-UV kwandisa isikhathi sokuphila se-mosaic yangaphandle. Izindawo ezivikelwe ze-alcove zisebenza kangcono kunezindawo zodonga ezivezwe ngokuphelele.
Uyigcina futhi uyihlanze kanjani i-mosaic ye-marble?
Hlanza njalo ngebhulashi elithambile noma indwangu ye-microfiber. Ukuze uhlanze ngokujulile, sebenzisa isihlanzi samatshe esingathathi hlangothi se-pH esifakwe ngendwangu emanzi bese womisa indawo ngokushesha. Gwema izihlanzi ezine-acidic noma ezirhabaxa ezilimaza izindawo zamatshe. Ukuhlolwa kwaminyaka yonke kwama-tesserae akhululekile kuvumela ukulungiswa kusenesikhathi ngaphambi kokuba izingcezu zilahleke.
Yisiphi isithombe sosayizi esisebenza kahle kakhulu ekuguqulweni kwe-mosaic?
Izithombe zedijithali ezinesinqumo esiphezulu zama-megapixel angu-20+ zinikeza umthombo ongcono kakhulu wokuguqulwa kwe-mosaic. Izithombe zekhanda zobungcweti ezinokukhanya okulawulwayo ziveza imiphumela emihle kakhulu ngoba ukukhanya okulinganayo kwenza kube lula ukumaka imibala yamatshe. Izithombe zesithombe ezinezithunzi ezinzima noma izizinda eziyinkimbinkimbi zidinga ukucutshungulwa kwesithombe okubanzi ngaphambi kokuguqulwa kwe-mosaic.
Ingabe amatshe ayigugu angasetshenziswa emifanekisweni eyenziwe ngokwezifiso ye-mosaic?
Amatshe ayigugu kancane njenge-tiger eye, i-lapis lazuli, ne-malachite angafakwa ezithombeni ze-mosaic zezindawo zokugqamisa okuhlanganisa ubucwebe, umbala wamehlo, nezinto zokuhlobisa. Lezi zinto zengeza imibala ehlukile engatholakali kumabula avamile. Izindleko zazo eziphakeme kanye nokutholakala kwazo okuncishisiwe kuvame ukuzikhawulela ekusetshenzisweni kokugqamisa ngaphakathi kwezakhiwo zemabula ezivame kakhulu.
