Kuyini isampula segolide nesiliva

Igolide nesiliva, abantu abaye basebenzisa kusukela ezikhathini zasendulo ukwenza ubucwebe, ngokwabo kuyizinsimbi ezincane kakhulu. Ngakho-ke, ama-alloys akhiwa ngawo, okunye okunye okubizwa nge-ligatures okungeziwe. Ukuze ku-alloys enjalo ukwazi okuqukethwe okuqondile kwesimbi eyigugu, sebenzisa amasampula egolide nesiliva, okubonisa okuqukethwe kwabo ku-alloy of jewelry.

Ngokokuqala ngqa emasimeni ejobile ejobile wegolide nesiliva afakwa ekhulwini le-XV. ERussia, ukufakwa kwezinto zegolide kwafakwa ngo-1700, futhi isiliva ngisho nangaphambili - ngo-1613. Lokhu kwaqinisekisa izinga lokuhlobisa. E-Russian Federation, isibonelo, ukukhishwa kwezimpahla zensimbi eziyigugu kwenziwa yihhovisi le-assay, futhi ukwakha isampula kahulumeni yegolide nesiliva kwimikhiqizo kushushiswa ngumthetho. Kodwa-ke, kwamanye amazwe, ukulawulwa kombuso phezu kwekhwalithi yama-alloys e-jewelry akusikho ngokuphelele, futhi ukukhishwa kwezinto zokucweba kwenziwa ngumenzi ngokwakhe.

Manje emhlabeni kukhona izinhlelo ezintathu eziyinhloko zamasampuli zegolide nesiliva - lokhu kuyimethrikhi, i-carat ne-spool. Ngesistimu yamatriki, lesi sampuli sibonisa inani lezingxenye zensimbi eyigugu equkethwe izingxenye ezingu-1000 ze-alloy. Ngesistimu ye-spool, iphadi elinamapulangwe angu-96 lisetshenziswe njengesilinganiso esiyinhloko. Ngesistimu yokukala i-karat, okuqukethwe kwensimbi eyigugu ku-alloy kunqunywa ngesisekelo sokuthi isisindo esisodwa sesisindo sihlukaniswe ngama-carats angu-24.

Inani lezithasiselo lithinta isampula, futhi uma usebenzisa izithasiselo ezihlukahlukene, kungenzeka ukuthola ama-alloyi ngezindawo ezilungiselelwe ngaphambilini, isibonelo, amandla anamandla nombala womkhiqizo oyigugu. Ngakho-ke, ekwenzeni ubucwebe, amasampuli ahlukahlukene ezinsimbi eziyigugu asetshenziselwa, kuye ngezinhloso zabo. Ngakho-ke, kunzima ukuphendula ngokungaqondile ukuthi yisiphi isampula segolide esingcono. Ngokuvamile isampula esiphezulu kunamasongo omshado wegolide, kodwa kakade amacici namaketanga akwenziwe ngegolide yesampula esinjalo, ngoba kufanele abe nokuhlala isikhathi eside.

E-Russia, amasampula amahlanu e-alloys egolide abhekwa njengegolide, 375, 500, 585, 750 kanye no-958. 375 isampula senziwa ngethusi nesiliva njengoba umgudu, ngokuya ngawo, unombala webala kusukela ophuzi kuya obomvu. Ezingxenyeni ezifanayo, kwenziwa amasampuli ama-500. Ngo- 585 isampula yengezwa nge-nickel ne-palladium, ikhiqiza i-alloy esetshenziswa kabanzi ekukhiqizeni ubucwebe. I-admixtures eyinhloko ye-alloy egolide yokuhlolwa kwezingu- 750 yilezo zethusi, isiliva, i-nickel ne-palladium, kodwa i-platinum nayo yenezelwa kubo. Le alloy inezinhlobonhlobo zembala kusukela ebomvu kuya eluhlaza ngokusebenzisa umbala ophuzi okhanyayo. Ngaphezu kokukhiqizwa kwezinto zokucweba, ngokuvamile kuvame ukusetshenziswa emisebenzini ye-filigree. I-alloy ye-958 igolide ayisetshenzisiwe kaningi, ngoba ayinamandla ngokwanele futhi ayinayo umbala ogcwele. Emhlabeni kunezinye izinhlamvu zegolide, isibonelo eLatin America ekukhiqizeni izinhlamvu zegolide isampula yegolide 875 isetshenziswa.

Ama-alloys esiliva ngezingubo zokugqoka asetshenziswa ngezingxenye ezincane zethusi. Okuthandwa kakhulu kulawa yisiliva yezingu-925. Kukhona namasampuli angu-875, 800 no-750-th. Asetshenziswanga kuphela ukukhiqizwa kwezinto zokucweba, kodwa futhi ekwenzeni izinto zokubeka ithebula. Ngokuhlukile kukhona i-alloy yesiliva yokuhlolwa kuka-960 - isetshenziselwa ukukhiqizwa kwemikhiqizo ye-filigree. Inezakhiwo ezinjalo eziyingqayizivele ukuthi imikhiqizo eyenziwe kusuka kuleso alloy enezinkampani ze-filigree ayisakwazi ukuphinda iphindwe kusuka kunoma iyiphi enye insimbi eyigugu. Ngakho-ke, kwenzeke ukuthi intengo yezinhlobonhlobo ezinjalo zesiliva iphakeme kunani lemikhiqizo yegolide.
