Ifeza ni imwe mu byuma bikundwa cyane ku isi yose, mu bihugu bimwe byubahwa ndetse n'ibirenze zahabu. Abashitani bahanganye bafata ifeza ntabwo ari ubwoko butandukanye bwo kuryamana gusa, ahubwo nanone kwitondaga, amasahani, ibindi bintu byingenzi. Igituba gikozwe muri iyi cyuma gifite ibyamamare byinshi.
Igisabwa na feza gisaba abaremwa cyimitako, bashiraho impeta, impeta na bracelets, barabahuza n'amabuye y'agaciro. Nubwo iyi cyuma kidahenze cyane, byatoranijwe kandi uhitamo abantu benshi b'imiryango.
Amafaranga yihariye
Ifeza ni plastike, iremereye, ariko yoroshye cyane. Ifite amashanyarazi meza numurongo wubushyuhe, bitewe nuburyo bukoreshwa cyane mubikorwa byinganda.
Ukuri gushimishije: Iyi cyuma ntabwo ishonga kubera ingaruka za acide za hydrochloric, ariko irashobora gusezererwa muri glande ya chlorine.
Ifeza ntabwo ari ibintu bio-element, ariko abahanga bagaragaje ko icyuma gifite imitungo ya antibacterial. Bamwe bemeza ko Niba uteye igiceri cya feza gisukuye mumazi, aba nyuma bazahanagurwa mikorobe. Ariko ibi ntibisobanura ko ari ngombwa guhora dukoresha amazi n'ibicuruzwa, "kwezwa" muri ubu buryo. Kwegeranya icyuma mu mubiri byuzuye ingaruka mbi n'indwara zikomeye. Ibirimo mu mazi yo kunywa birashobora guteza akaga cyane.
Nibyiza kubika ibintu bya feza n'imitako kure ya iyode, kuko iyo binjiye kuri we, bazijimye. Uku "kwanduza" ntibuzasukura neza.
Byemezwa ko imitako ya feza ihenze, bityo abaguzi bakunze guhitamo impinduka ziva muri feza hamwe nibindi byuma. Ariko siko bimeze. Icyuma muburyo bwera ntizishimira imitungo ifatika kandi yoroshye, niyo mpamvu abahanga bavanga numuringa, Titanium cyangwa platine.
Ababigize umwuga bagaragaye ko ku isi 20% gusa bya feza bijya kurema imitako. Ibicuruzwa bikozwe mu ibyuma bitanduye ntabwo byijimye byihuse, ariko nanone byashushanyijeho byoroshye, mugihe alloys zitandukanye zifite ubukana kandi buke cyane kubyangiritse. Master Alloys nayo yitwa Liguture.
Murakoze kubaho muri ligature zitandukanye, imitako yumwuga irashobora gukora ibicuruzwa byinshi ukoresheje tekinike igoye.
Ntigomba gufatwa ko alloys igomba kuba icyuma gihekeshye, kubinyuranye nabyo, bituma birushaho kwihanganira kandi bikurura. Ariko ntiwumve, ntukibagirwe ubwitonzi bukwiye, kubera ko na borozi ba feza basanzwe bafite umwanya wo Kwijimye kandi byanduye.
Ubwoko nibiranga
Kuri feza yuzuye uyumunsi, umuringa uhari cyane. Inzobere ziboneka ko icyuma byombi gikora neza hamwe. Ariko ibi ntibirangira muribi - akenshi nikel, zinc, cadmium, kimwe nibindi bintu bishobora kuboneka byoroshye muri sisitemu yigihe (Imbonerahamwe) yongeyeho kuri ligature hamwe numuringa. Nikel akenshi ikoreshwa cyane kugirango itange akamenyetso.
Sterling ifeza ifatwa nkigihe ihenze kandi ikunzwe, aho hari uruvange rwumuringa. Iyi myuga ikubiyemo feza irenga 92%.
Ifeza, kimwe no guhagarika, ni kimwe mu bihenze kandi gishakishwa. Inzobere zirimo itsinda rya platine kubera kwambara cyane no kunoza amakuru yo hanze.
Imwe mubwoko buzwi ni ifeza ya fikori, ari ibyuma muburyo bwiza. Bikoreshwa kenshi kubitekerezo bidafite imipaka.
Ifeza y'umukara Biragaragara ko wongeyeho umuringa no kuyobora. Umukara utandukanye ni okiside ifeza.
Ifeza ya feri yashyizweho ukoresheje zahabu, umuringa cyangwa umuringa muri Liguture. Imitako nkiyi nigihe irashobora kwijimye kandi isa numuringa.
Niba 1% nikel iboneka muri ligature, bivuze ko imbaraga zabicuruzwa ejo hazaza, kimwe no kurwanya ihohoterwa, iziyongera, ariko ibirimo Nickel bizagenda byoroshye. Hagomba kubaho hagati ya zahabu.
Ibirimo bya aluminium muri sillof axloy birenga 6% bizanatera imvange nziza. Ni nako bigenda kubintu binini bya zinc, bishobora kugabanya byibuze ibintu byose byingirakamaro byibyuma.
Ifeza ihindura ibyuma ntabwo ari intungane cyane, bityo rero gake cyane. Ni nako bigenda kuri tin, bituma airloy dim.
Ifeza-palladium alloys ikoreshwa cyane muri bamenyo yo gufata proshetike nziza.
Gusaba
Urugero rwa feza rukoreshwa biterwa nicyitegererezo cyacyo. Uyu munsi, igihugu cyacu gikoresha ingero 8 yiyi mezi. Mubitekerezeho birambuye.
- 720. Ibyuma biri hasi, muri ligature yumuringa wiganje, utange igicucu cyumuhondo. Kubera ntabwo ari ibintu bishimishije cyane, icyuma cyiyi ngero ntigikoreshwa mumitako.
- 800 na 830. Amakuru ya Alloys nayo ntaho ahuriye n'imitako kubera ibirindiro byinshi, ariko birenga intoki nibindi bintu byo gukoresha burimunsi.
- 875. Ubukorikori bukoreshwa mumitako, kubera ko ifeza nziza irenga 87% muri yo, ifite amakuru asa na zahabu yera, akenshi akoresha abashuka, atanga ibicuruzwa, atanga ibicuruzwa kubandi.
- 916. Uyu munsi, ibi bikoresho ntabwo bikoreshwa mugukora imitako. Mu gihe cy'Abasoviyeti bivuye mu cyuma cy'iyi ntebe, gahunda y'abaguzi yakozwe neza: inzangano, igiti cya silver, ibikombe by'isukari, n'ibindi.
- 925. Uru rugero nimwe mubashakishijwe cyane - nyuma, bihura nubuziranenge bwose bwiza. Icyuma kigaragaza ubwiza bwose bwibicuruzwa bya feza. Birazwi ko ibiceri byicyongereza byacukuwe mucyuma cya 925, kubera ibyo yiswe "ifeza ya silver".
- 960. Muri iyi alloy 96% bya feza isukuye, ni ngombwa kuyikoresha kugirango ukore ibicuruzwa, bizatwikirwa na enamel. Ibicuruzwa biva muri feza hafi ya byose byitonda, hagomba kwitabwaho byihariye, bitabaye ibyo birashobora kwangirika byoroshye.
- 999. Isuku isukura ikoreshwa mugukora ibiceri byegeranye no gutera Ingot Ingots.
Ibindi bikoresho bizwi kandi ko bidafite ingero, nkuko birimo ingano ntoya. Duhereye kuri aya alloys atuma imitako idahembwa kurwego rwa Brooch kandi impeta yoroshye.
Hariho kandi ikubiyemo ko ifeza ya mimic kandi ntukore kuri yo, nta feza hariya. Nk'uko amategeko, Nickel, icyuma na Manganese bari muri bo. Kwigana aya makuru ntibishoboka gutandukanya ijisho nyaryo. Ubu bwoko bwa alloy bwitwa Melchior Bikoreshwa cyane mugukora imitako idahenze kandi ikomatanya.
Ibyifuzo byo kwita kubihembwa bya feza reba videwo hepfo.
