Sterling Silver

Isilivere isetyenzisiwe kwizinto zokugqoka kuvala mandulo. Imigodi yayo enkulu yemayini yaqala eYurophu ngekhulu le-18. Kuze kube ngulo xesha, ngenxa yokungabi nakwazi idizithi eziyaziwayo, zachithwa ngobuncinane.

Ngokwebonakala, isilivere esineqhekeza imhlophe ngokumhlophe, ngokuqhaqhaqhaqhaqhaqhaqhako okubonisa ukuba abantu abathandana nabo baqhathaniswa nokukhanya kwenyanga. Oku kunokwenzeka ukuba lo mzekeliso uvela kwixesha elidlulileyo, xa isilivere ithathwa njengophawu lwenyanga, ngelixa igolide liwuphawu lweLanga.

Le ngxube yelitye yamandla aphezulu, ahlala enamandla kwaye asebenzayo. Ubeka into evuyayo ngeplatinum negolide emhlophe, ngelixa ixabiso legolide elimhlophe liphantsi kakhulu.

Imveliso eyenziwe kwesi silivere ineempawu ezizodwa. Leli lizwi elithi "sterling" okanye uphawu oluthile (kuxhomekeke kwilizwe apho iimveliso zenziwe khona).

Namhlanje, le nxalenye iyinkokheli ekuthandeni ekuveliseni ubucwebe kwiintsika ezixabisekileyo. Isiliva lihle, lihlanjululwe, lihlala lide kwaye, kubalulekile, i-hypoallergenic.

Nangona kunjalo, akuyena wonke umntu onokucinga ukuba yiyiphi i siliva enhle. Yimbumba yesilivere kunye nobhedu. Izitshixo zixutywe kwiqondo lokushisa eliphezulu (ngaphezu kweyure nesiqingatha sama-degrees), okubangelwa kwinqaku elinqabileyo elingazange lilahlekelwe ubuhle balo bangaphandle ixesha elide. Ivelisa iingubo kunye nokusika, izixhobo zonqulo, i-cufflinks, izikhonkwane zomtya, njl njl.

Ngendlela yayo ecocekileyo, isilivere ayisoze isetyenziselwa ukwenza nayiphi na imveliso, kuba le ntsimbi ilula kwaye ilula. Ngako oko, ezinye izinyithi ezineendawo ezixabisekileyo zihlala zongezwa kuyo ukuze zinike amandla: i-zinc, ithusi, i-nickel, i-germanium kunye ne-platinum.

Ipesenti yale alloy zilandelayo: isilivere - 92.5% kunye nobhedu - 7.5%. Yilezi zixa kufuneka zibe khona kwi-alloy ebizwa nge-925 yesiliva esinezantsi.

Ukuba khona kobhedu kwi-alloy kungabangela ukuba xa kudibana nomoya, ekugqibeleni ukhula utyhafile kwaye ubumnyama. Ukubuyisela umkhiqizo wesilivere umbala wokuqala kunye nokukhanya, kufuneka ugcinwe kakuhle kwaye uhlambuluke ngexesha elifanelekileyo.

Gcina isilivere esicatshulwa kwiibhotile ezivaliweyo okanye iibhegi zenyama, endaweni epholile kunye eyomileyo. Ngamanye amaxesha, iimveliso kufuneka zihlanjululwe ngamanzi ashushu usebenzisa i-detergent yesiqhelo. Emva koko, umhlobiso udinga ukucinywa ngendwangu elithambileyo. Kwakhona, isiliva ingahlambuluka ngeendlela ezingabandakanyi i-phosphates. Ukuba kwenzeka njalo ukuba umhlobiso usabumnyama, ngoko kukulungele ukuyibeka kwi-professional. Iimpahla ze-Jewelers zineenqwelo ezinkulu zeendlela apho iimveliso zingabuyisela ukukhanya kwangaphambili. Kwakhona ukukhuselwa kwesilivere kuya kuhlanganiswa ngononophelo oluthile lwe rhodium.

I-Sterling 925 yesilivere yinguqulo yeklasi yale alloy. Ekubunjweni kwayo, kuhlala kukho ubungakanani besilivere: ama-925 ngamanqaku angama-1000 e-alloy eqediweyo.

Isilivere esinezantsi ngokwemali yesiNgesi iqukethe ii-ounces ezi-11 kunye nama-48 weensimbi ezintle. Ukubalisa ukusebenzisa inkqubo enjalo yokulinganisa: enye ipondo ilingana nama-ounces ayi-12, oko kukuthi, kwisixa sama-373.24195 amagremu; Ngamanye ama-pennies angama-20, ngokupheleleyo - 31.1035 amagremu; I penny enye ilingana nama-24, i-1,555 iigremu.

Igama le-alloy liphuma kwintsapho yePasterling, eyayiphila ngasenyakatho yeJamani kwi-XIII leminyaka. U-Edward wakhe owokuqala wanikezela ilungelo elihloniphekileyo lokufumana iimali zesiliva, ezathi zaziwa ngokugqithiseleyo ngomgangatho wazo. Kwaye kwakhiwa igama elifanayo "elihle". Ukususela ngeli xesha, eli gama libizwa ngokuba lizinga eliphezulu lokuthembeka kunye nomgangatho. Nangona kunjalo, oku akusiyo kuphela inguqulelo yemvelaphi yegama elithi "sterling" ngokumalunga nesilivere. Nangona kunjalo, intle kakhulu, njengensimbi ebonakalayo.
