Ndi siliva chitsanzo Kodi

Ngakhale kuti tili kale anazolowera chaka phindu ubale siliva kwambiri m'munsi kuposa kuti opangidwa kuchokera ku golide, siliva, malingana aloyi, ntchito siliva ndi mayesero kungalire golide kwambiri. Kumene, zina, mbali yofunika ndi ankaimba ndi ntchito suoneka jeweler, chifukwa ena njira filigree wa kupanga zibangili sangathe mobwerezabwereza pamene ntchito ndi golide. Koma ambiri a udindo wofunika kwambiri ankaimba ndi chitsanzo.

Kawirikawiri zodzikongoletsera sakhala wa woyenga zitsulo mfulu, chifukwa chakuti nambala inayake ya kuipa. Mwachitsanzo, koyera siliva - ndi Zipangizo zofewa kwambiri, choncho amapangidwa ndi aloyi ndi Kuwonjezera wa wochepa mkuwa kusintha mphamvu yake. Okhutira mkuwa ndi aloyi mu chitsanzo ndiyo kuchuluka siliva ndi ungwiro. Nthawi zina kwambiri "kulimbikitsa" siliva, miyala ina ntchito, zina ntchito faifi tambala, zotayidwa, nthaka ndi cadmium. Koma nthawi zambiri kwa aloyi siliva chuma timatsatira ndi mkuwa.

Pa nyemba mkulu wa siliva mkuwa amene ali pano ndalama kochepa, ndi zokoma woyera mthunzi, kuwala chikasu kulocha kokha siliva ali chitsanzo kuthungo. Koma aloyi mtengo kwambiri za siliva ankaona kuti ndi aloyi ndi cadmium ndipo kawirikawiri milandu adalenga kuchokera mmenemo siliva zodzikongoletsera ofunika kwambiri kuposa golide. M'mayiko ambiri a dziko pofotokoza chitsanzo siliva anatenga dongosolo chinkafunika. Pamene zili chitsanzo chiwerengero cha chitsulo gawo chabwino chikwi mbali (kulemera mayunitsi) aloyi. Zolemba malire kwa miyala yamtengo wapatali ndi 960 siliva, limodzi ndi, pali 925, 916, 875, 800 ndi 750 Ine. Chikalata Russian aona kuti zodzikongoletsera ali ndi mfulu zitsulo zili zitsanzo zosakwana 800, amene anatsimikiza ndi osachepera, ndiye mu nkhani iyi iwo sali pansi boma ndi manyazi omwe anazindikira kale monga mankhwala opangidwa ndi zitsulo m'munsi.

mankhwala amenewa nthawi zambiri amapezeka mu moyo wa tsiku ndi tsiku, amene ntchito monga chuma kwa akasupe, zikhomo, solder ndi zina zotero. Chifukwa chaichi aloyi zasiliva 720 zitsanzo. Koma m'mayiko European nthawi zambiri zotheka kukumana yaing'ono Chalk zovala kuwazungulira 750. Komabe, kuwonongedwa ambiri ku Ulaya akuti ndi 925-I, kupatula mu France, kumene 800 Ine ndi ofala.

Chitsanzo apamwamba 960 ntchito popanga zabwino filigree zodzikongoletsera, monga okha amalola kukonzekera aloyi siliva zace filaments kenako ambuye kuchita kanjedza openwork. No wapatali zitsulo mwayi zina sasunga. Kupereka mphamvu mankhwala filigree iwo anapangidwa nthawi zambiri zasiliva aloyi cadmium, kwa amene analandira ndi zapamwamba openwork filigree (zingwe chitsanzo, amene ali kuoneka bwino kudzera zimakwana). Komabe, mu nkhani iyi, phindu analandira zokongoletsa za kuwonjezeka aloyi kwambiri.

Tiyenera kuganizira mmene kubala kukonza siliva. zosowa zawo loyamba kusamba ndi madzi ofunda ndi sopo kenako kupaka phala choko, ankawaviika amoniya madzi. Pamene youma osakaniza anali ntchito, mankhwala ayenera bwinobwino rinsed ndi madzi ndi kupukuta ndi kansalu zofewa. Ngati mankhwala oxidized siliva, ayenera kutsukidwa ndi amadzimadzi njira ya sulphate ndi sodium. ziwiya Silver ayenera kutsukidwa komanso siliva woyenga 925, amene amangoona anapanga mipeni siliva, mafoloko ndi spoons. Kuti tikhalebe luster zawo pambuyo ntchito, mbale ayenera choviikidwa mu madzi otentha ndi makeke pang'ono.
