He aha te mea tauira hiriwa

Ahakoa te meka e kua taunga kē tatou ki te whakatau tata i te uara o whanaunga hiriwa ko nui i raro i taua hanga i te koura, he hiriwa, i runga i te koranu rānei, kia utu mahi hiriwa me te whakamātautau atu koura. O te akoranga, i roto i ētahi wā, te takaro he wāhi tino hira te e te mahi nanakia rei, no te mea e kore e taea te tukurua etahi tikanga nohoanga o te whakapaipai, ka mahi ki te koura. Ko te nuinga o te wāhi nui takaro e te tauira.

Ko te tikanga e kore te whakapaipai i hanga o parakore konganuku rangatira, mai to ratou he maha etahi o huakore. Hei tauira, te hiriwa parakore - he he rauemi rawa ngohengohe, na kua meinga reira i te koranu ki te tua o te moni iti o te parahi ki te whakapai ake i tona kaha. Ko te ihirangi o te parahi i roto i te koranu i roto i te tauira whakatau te ōrau o te hiriwa me te viivii ore. I roto i te wā tino onge mō "whakapakari i" o hiriwa, e whakamahia atu konganuku, tāpiritanga whakamahia hoki nika, konumohe, te konutea me te cadmium. Otiia i roto i nuinga o te wā mo te rauemi matua koranu hiriwa he parahi.

I tenei tauira nui o hiriwa i roto i te parahi i te reira i roto i te moni iti, he atarangi ma reka, he kauruku kōwhai marama anake hiriwa kua te tauira i raro. Ko whakaaro te koranu tino utu o te hiriwa e ki he koranu ki cadmium me maha i roto i enei take i hanga i reira whakapaipai hiriwa utu neke atu i te koura. I roto i te nuinga o nga whenua o te ao ki te tirohia ki te tauira hiriwa tangohia te pūnaha ngahuru. A, no te te tohu te reira i roto i te maha tauira o te wahi whakarewa pai i roto i te kotahi mano ngā wāhanga (wae taimaha) koranu. Mōrahi mō te rei ko 960 hiriwa, a me taua mea, i reira e 925, 916, 875, 800 me 750-ahau. kitea te mōhiohio Russian e ki te he ihirangi whakarewa pai o iti iho i te 800 ngā tauira, whakaritea nei e te iti te whakapaipai, ka kore i roto i tenei take e ratou raro ki te kāwanatanga me te taupae e mohio kua rite ngā hua i hanga o turanga whakarewa.

Ka taea e maha ēnei hua e kitea i roto i te ora rā, e kua whakamahia rite rauemi mō puna, titi, tūhoto, me te pera i runga i. Hoki tenei whakaaro i te koranu hiriwa, ko te 720 ngā tauira. Otiia i roto i te whenua Pākehā ko reira taea maha ki te whakatau iti oko kakahu a tawhio noa ratou 750. Heoi, whakaaro te rärangi tino noa i roto i Europe te ki kia 925-ahau, ki te kahore i France, kei hea he atu noa 800-ahau.

Ko te tauira teitei 960 whakamahia mō te hokohoko i te whakapaipai nohoanga pai, pērā i anake taea ki te faaineine i koranu hiriwa ona kakawaea e ka rangatira mahi tau openwork. e kore e No atu whakarewa utu nui taua whai wāhitanga riro. Hei hoatu hua nohoanga kaha e hanga e ratou maha hanga o koranu cadmium hiriwa, i nei whiwhi te he pai openwork nohoanga (tauira miro, i te mea mārama kitea i roto i te ahua). Heoi, i roto i tenei take, i whiwhi ai te uara whakapaipai o nga piki koranu tino.

kia arotahi hoki tatou i runga i te āhua o ki te whakaputa hiriwa horoi. Ratou hiahia tuatahi ki te horoi ki te wai mahana me te hopi, me te ka pani pāreti o kotakota, haurangi i roto i te haukini wai. A, no te maroke i tono te ranunga, te hua kia ata horoi ki te wai, me te muru maroke ki te kakahu maeneene. Ki te hua hiriwa oxidized, Me ratou ki kia horoia ki te wairewa o te konutai pūkawa. kia horoia rite te pai oko hiriwa rite hiriwa parakore 925, te nuinga kei te i hanga o maripi hiriwa, marau, me koko. E mau tonu ratou ratou mau umeraa i muri te whakamahi, kia tukua hoki nga rihi i roto i te wai kohua ki te houra iti.
