As nā mīkini hana gulamea hana, kaʻana like mākou i ka ʻike gula no nā mea kūʻai aku.

Hoʻohui ʻia ke gula me nā metala e like me ke keleawe a me ke kālā ke hoʻohana ʻia e hana i nā mea nani.ʻO ke gula keʻokeʻo ʻaʻole ia he mea i loko ona iho, akā he gula wale nō i hui pū ʻia me nā metala ʻē aʻe e hana i kahi nānā kālā.ʻO nā metala maʻamau i hoʻohana ʻia i ke gula keʻokeʻo he nickel a palladium, a i ʻole zinc a tin paha.

HUI HUI NO KA HANA NUI

ʻIke ʻoe i nā metala āu e ʻaʻahu nei?

Pīhoihoi paha ʻoe i ka ʻike ʻana i ka nui o nā metala a me nā ʻāpana like ʻole i komo i loko o kāu mea nani a i kou kino.Ma William Rowland, haʻaheo mākou i ka hāʻawi ʻana i nā metala maʻemaʻe kiʻekiʻe a me nā alloys i nā ʻano ʻoihana a puni ka honua.

ʻO nā ʻano metala koʻikoʻi a mākou e noʻonoʻo ai i ka hana ʻana i nā mea nani he kālā a me ke gula, akā ʻo ka hapa nui o nā mea nani ʻaʻole i hana ʻia i ke kālā maʻemaʻe a me ke gula.ʻO ke kumu o kēia ma ko lākou ʻano maʻemaʻe, ʻoi aku ka palupalu o ke kālā a me ke gula ʻaʻole hiki ke kūpono i ka nui o nā mea nani.Loaʻa i nā metala nā waiwai kūʻokoʻa e kūpono ai no nā hana kikoʻī, a ʻo ia ke kumu e pono ai ke kamaʻilio me kahi mea kālepa metala akamai i ke kauoha ʻana.

Ua kapa ʻia ke ʻano kālā maʻemaʻe he 'kālā maikaʻi' a hoʻohana nui ʻia kēia no ka bullion, ʻaʻole i nā mea nani a i ʻole kālā, no ka mea he palupalu.He maʻalahi loa ke kala i ka ʻino, a hiki i ka hui ʻana me nā metala ʻē aʻe ke pale i kēia.Akā, hoʻohana ʻia ke kālā sterling.He 92.5% ka maʻemaʻe, akā ua hui pū ʻia ke koena me nā metala ʻē aʻe e like me ke keleawe, zinc a i ʻole silika.

Pēlā nō, mālama ʻia ke gula ma kona ʻano maʻemaʻe no ka bullion, no ka mea he palupalu a hiki ke lilo i hewa i loko o nā mea nani a i ʻole ke kālā.Hoʻohui ʻia ke gula me nā metala e like me ke keleawe a me ke kālā ke hoʻohana ʻia e hana i nā mea nani.ʻO ke gula keʻokeʻo ʻaʻole ia he mea i loko ona iho, akā he gula wale nō i hui pū ʻia me nā metala ʻē aʻe e hana i kahi nānā kālā.ʻO nā metala maʻamau i hoʻohana ʻia i ke gula keʻokeʻo he nickel a palladium, a i ʻole zinc a tin paha.

Aia kekahi hui gula like ʻole e hana i nā kala like ʻole a me nā hopena.ʻO ke gula rose he hui ʻia o ke gula melemele, ke kālā a me ke keleawe, e hana ai i ka ʻulaʻula ʻulaʻula, a ke ʻike mau ʻia nei nā hui metala hou no nā mea nani.

Ma Hasung ʻike mākou i ka metala a ua hana mākou i ka hana ʻana i nā mea metala makamae a puni mai ka makahiki 2000 ua loaʻa iā mākou kahi ʻike kūʻokoʻa o kā lākou mau waiwai a me nā mea kūpono no ka lehulehu o nā noi.Ke kūʻai aku ʻoe i nā metala ma ka mākeke, inā ma ke kau ʻana i kahi kauoha ma ka hale kūʻai pūnaewele, a i ʻole ma ka hui metala kūloko, e hōʻoia ʻoe e loaʻa nā metala kūpono, ma ka hoʻohana ʻana i kahiʻIkepili XRF, e loaʻa iā ʻoe ka noʻonoʻo maikaʻi e kiʻi i nā metala kūpono āu e pono ai.
