Malunga nobucwebe begolide nesilivere

Yeyona ntsimbi kuphela enombala omhle wendalo oqaqambileyo omthubi. Kwimeko yokunyamekela kakuhle, izinto zobucwebe begolide zinobomi obude kakhulu. Akumangalisi ukuba igolide esihlala sikhetha ngayo imisesane yomtshato. Ukuqina kwegolide kukholelwa ukuba komeleza usapho kunye nolonwabo kunye nethamsanqa. Enyanisweni, igolide ikho kuyo yonke indawo; kwizityalo, elwandle, emilanjeni, njalo njalo, kodwa kunzima kakhulu ukutsalwa. Inyaniso yokuba unokwelula i-1g yegolide kwintambo engaphezulu kweekhilomitha ezi-2 ubude ifika ibe yinto emangalisayo.

Igolide ecocekileyo ithambile kakhulu, ayihlali kwaye inzima ukusebenza nayo. Kungenxa yoko le nto ubucwebe buxutywe kunye nezinye izinyithi ezifana nesilivere, ubhedu, i-zinc, i-nickel. Ukusetyenziswa kwe-alloys kwenza igolide ibe lukhuni kwaye iboleka umbala. Umzekelo, ubhedu kunye nesilivere zigcina umbala otyheli, ngelixa i-nickel, i-zinc kunye ne-palladium zivelisa i-alloys ezinombala omhlophe. Ubucwebe befashoni ngoku benziwa ngeendlela ezahlukeneyo ezifana nepinki okanye irose.

Umlinganiselo wegolide kwii-alloys uchazwe kwiikarats. Nantsi imigangatho yekarati yegolide esetyenziswa ekwenzeni ubucwebe:

24karat (24K) igolide yigolide ngokwayo, inguqulelo yayo esulungekileyo.

I-14karat (14K) igolide iqulethe iinxalenye zegolide ezili-14, exutywe kuyo yonke indawo kunye neenxalenye ezili-10 zezinye iintsimbi.

Okukhona umlinganiselo wekarati uphezulu, kokukhona uphezulu umlinganiselo wegolide kwiqhekeza lezacholo.

Uninzi lwezacholo luphawulwe ngomgangatho wekarat, nangona kungafunwa ngumthetho. Kodwa kufutshane nomgangatho wekarat uphawu kufuneka kubekho igama le-U.S. uphawu lwentengiso olubhalisiweyo lwenkampani eya kuma emva kophawu. Ungaze uthenge iziqwenga zobucwebe ngaphandle kophawu kufutshane nomgangatho wekarat.

Iipropathi ezingaqondakaliyo zegolide zinomdla kakhulu ukwazi: Yenye yeentsimbi zokuqala ezaziwa luluntu. Kwakukho amaxesha apho ukutya kwisitya segolide kwakugqalwa njengokuncwina koxolo kunye nesifungo sokunyaniseka xa kusenzelwa umthunywa wesizwe esinobutshaba. Umthunywa unokuqiniseka ukuba ukutya akutyhefwe njengoko igolide ingenako ukudibana neetyhefu.

KwiGrisi neRoma yamandulo amacwecwe egolide anomfanekiso womntu okroliweyo kuwo ayesetyenziswa njengesixhobo sokuthakatha.

Kumaxesha amandulo le ntsimbi yayigqalwa njengenyanga iintlungu zentliziyo, ukudandatheka kwengqondo kunye neentloni. Ootatomkhulu bethu babekholelwa ngokwenene ukuba igolide inokuvuselela umsebenzi wakho wengqondo nentliziyo, iphucule inkumbulo kwaye ivuse indalo yakho yokomoya, ukuba yayilele ngoku. Kwaye, ngendlela, igolide isetyenziselwa amayeza ukuza kuthi ga ngoku. Nazi ezinye zeenkolelo ezidumileyo malunga negolide:

- Bamba igolide emlonyeni, kwaye iya kwenza umoya omtsha kwaye unyange izifo zomqala.

- Ukuba indlebe ihlatywe ngenaliti yegolide, umngxuma awusokuze uvale.

-Ukuba umntwana unentsimbi yomqala yegolide, akayi kulila.

-Igolide ikhusela kunxunguphalo kwaye xa iyonke igolide engakumbi onayo nawe kokukhona ujollier.

-Ukutshiswa kwentliziyo ngegolide kunyanga iintlungu zentliziyo.

Igolide luphawu lothando kunye nesigxina, ngoko ke ubucwebe begolide bufanelekile ukunika abantu abathandekayo. Ngaphandle koko, iyamangalisa kubantu abadala njengoko, ekubeni yintsimbi yeLanga, igolide ngowona mthombo wamandla kubo.

ISilivere yeSilivere iyeyesibini intsimbi edumileyo emva kwegolide. Imbali yayo ibuyela kumaxesha amandulo aseByzantium, amaFenike kunye noBukhosi baseYiputa.

Kumaxesha amandulo isilivere yayiyenye yeentsimbi ezizithandayo zeAlchemists, iNyanga yesinyithi ngenxa yesiphumo sayo sokupholisa. Izifo ezininzi zanyangwa ngamayeza anomxholo wesilivere.

Kwimo yayo esulungekileyo isilivere ithambile kwaye yiyo loo nto ihlala ixutywa nezinye iintsimbi.

- Isilivere yengqekembe ibhekisa kwi-90% yesilivere esulungekileyo ene-10% yealloy yesinyithi.

- Isilivere yaseJamani okanye isilivere ye-nickel ngumxube we-nickel, ubhedu kunye ne-zinc.

- Isilivere ye-Sterling yi-92, i-5% yesilivere ecocekileyo kunye ne-7, i-5% yobhedu. Ubhedu yeyona alloy yesilivere njengoko iphucula ubulukhuni bentsimbi ngaphandle kokuchaphazela umbala oqaqambileyo. Ubucwebe besilivere beSterling buhlala buphawulwa njengesilivere eqaqambileyo, isilivere eqaqambileyo, i-sterling, okanye i-925.

Mhlawumbi ngenxa yepropati yokupholisa isilivere ithathwa njengentsimbi efanelekileyo yokugqoka abantu abaneempawu zabo ngokukhawuleza, ukuthetha ngokukhawuleza. Isilivere inceda ukususa uloyiko lokuhlala emva kwexesha kunye noloyiko lwemiphumo emibi enokwenzeka yezenzo ezicwangcisiweyo. Kwaye omnye umqondiso wabantu abathambekele kwisilivere lizinyo elimnandi.

Isilivere isetyenziselwa ukusetwa kwendabuko kumatye anqabileyo, okubanika inkangeleko ephucukileyo ngaphandle kokuya phezulu. Ubucwebe besilivere sisipho esithandwayo kubasetyhini nabantwana. Nokuba ngamakhonkco esilivere, iintsimbi zomqala kunye namatyathanga okanye amakhubalo kunye nependants, ubucwebe besilivere bubukeka bubuhle kwaye bugqwesile. Ngumdlalo ofanelekileyo kwimpahla yemihla ngemihla. Amadoda angaphiwa amakhonkco ekhafu yesilivere kunye namakhonkco okutyikitya. Luphawu lweemvakalelo ezithambileyo okanye inkumbulo yothando. Ngendlela, ngaba uyazi ukuba ubucwebe besilivere bugqitywe ngexesha elithile bufumana i-patina eyahluka ngokwemichiza yomntu oyinxibileyo? Yizame nomnye umntu kwaye uya kumangaliswa kukubona iziphumo ezahlukeneyo.
