Chii ndozvakanga nendarama

Akadaro anokudzwa simbi akadai goridhe kazhinji anopinda ruoko rwomunhu zvayo yakachena chimiro. Kazhinji vaya zvinogadzirwa kuti yatinoti goridhe vanenge chiwanikwa zvendarama ligatures. Ligature akakudzwa non-ferrous simbi tsvina. tsvina aya vakawedzera kusvika chiwanikwa, anoshandiswa kuvandudza chokupika nohumwe unhu zvakakodzera sezvo pachayo chicherwa rinokosha chaizvo nyoro wayo yakachena chimiro. Gold racho yakaisvonaka chimiro iri pachena kuti rinorema abrasion, uye zvigadzirwa kuti vari kunze chinogona kuitwa, nyore nyore ndikamumara achaita uye nokuputsanya kakawanda.

Kunyange kare, masayendisiti vakatsunga kuti yakaisvonaka ligature goridhe sirivha nemhangura. Naizvozvo, vakanga vawedzera kusvika alloys nendarama uwandu siyana. Uye kuti kukwanisa kuziva uwandu akawedzera ligatures mu alloys nokuti nokuita zvishongo vakatanga kushandisa mimwe goridhe. Ndiko, munyika yanhasi, kunaka chero kwezvishongo uye zvishongo kubva anokosha simbi chigadzirwa hakubvi chii (tsvuku kana chena) goridhe kushandiswa kwayo kugadzirwa, uye kubva zvavo netsvina kugutsikana, izvo anovapa simba uye mukurumari.

Vazhinji izvi zvishongo wakaumbwa 585 goridhe. Zvimwe zvinhu nokuda kugadzirwa zvishongo kusiyanisa mutsvuku, yellow uye chena nendarama. Red Gold rinobudiswa nokuwedzera kwazviri yemhangura anowedzera raro simba uye mukurumari. Kana yero ligatures vari aiwanzoshandiswa sirivha, uye kuwana chena akawedzera chiwanikwa pamusoro nickel uye palladium. Kare kushandiswa hurongwa maviri kuona muenzaniso goridhe - munhu carat uye arşive. On muganhu Russia dzinowanzotsigi- akashandisa arşive hurongwa, inobva kutsunga kurema zvinokosha simbi iri thousandths nevazhinji zvigadzirwa. Saka nyore kunzwisisa chii vari mimwe goridhe. Somuenzaniso, 1000 magiramu vana 585 chiwanikwa rine 585 magiramu nendarama yakaisvonaka uye 415 magiramu ose ligatures. Saizvozvowo, mharidzo akatsunga, nendarama chena.

Carat goridhe yokuenzanisira vasabatwa gadziriro iri kunyanya kushandiswa UK, Europe uye USA. Panyaya iyi, zita rokuti rinoitwa mu carats. Carat kunotsanangurwa somunhu maviri namana kurema yegoridhe chiwanikwa. Naizvozvo wakachena anokosha simbi ane 24K, mharidzo 750 anoenderana 18K, mharidzo 375 rine 9k. Kupfuura zvakakurumbira munyika rinoshandisa goridhe chiwanikwa kuti 750 nemiedzo. Chero ruvara Gold zvinhu dzinoitwa nokushandiswa ichi mharidzo goridhe. Kusiyana ruvara zvishongo kuzadzisa kushandisa chokwadi chokuti Kuronga alloys anowedzerwa ne siyana anokosha nesimbi - palladium, iridium, rhodium, chromium uye zinc.

Saka, mazuva ano zvishongo musika ndiyo hombe pamberi rebhuruu goridhe, mutema goridhe, akasimuka goridhe, dema ndarama, uyewo ndarama chena. Zvisinei, vakawanda asi zviri yero uye mubatanidzwa nendarama tsvuku uye chena. Asi muupenyu hwezuva nezuva anowanzonzi kuwanikwa alloys ose ivhu zvina: 375, 585, 750, uye 958. Gold chiwanikwa 958 ivhu anowanzodanwa kushandiswa pakugadzira mabasa ounyanzvi. Kune 900 mharidzo, izvo munyika dzakawanda kuti dzava kugadzira Mari zvendarama dentistry. Kana Kushongedza dzinoitwa kubva alloys kuti asingasviki 375 ivhu, ipapo havachisiri kuonekwa zvishongo, vanotaurwa nezvavo zvishongo.

Munyika dzakawanda munyika iri kugadzirwa zvishongo wehurumende anoratidza masimba pamusoro zviri zvendarama alloys. Mune dzimwe inoti kunyange kuva kudzora jewelers makambani kuti vane zvavo zvikuru kunzwisisa uye siyana rusarura. Zvisinei, mune dzimwe nyika, dzakadai Egipita, Turkey, USA uye nyika South America, hapana hurumende kudzora kugadzirwa mishonga goridhe.
