Ke piʻi nui nei kaʻulaʻula gula ma ka noiʻana i mea e hana ai i nā mea waiwai. ʻAʻole wale nā haku, akā, ua mahalo nui nā mea hoʻohana i kona nani a me kona mana. Akā, he nui nā mea kūʻai e pili ana i ka koho, aʻo iaʻano hōʻailona e pono ai i nā mea i hanaʻia i ke gula keʻokeʻo.
He aha nāʻano o ke gula keʻokeʻo?
E like me kouʻike, heʻoluʻolu loa ke gula maʻemaʻe aʻaʻole kūpono i ka hanaʻino i ke kila. No laila, no nā hana hana nani, ua hoʻohana nuiʻia nā'āpana mai nāʻokoʻa likeʻole a me ke gula, a hāʻawi iā lākou i ka ikaika. Hōʻike ka mea hōʻike i ka nui o ke gula maikaʻi i hoʻohanaʻia ma kēia a me nā mea e hana ai. ʻO ka meaʻoi aʻe,ʻo ia ka mea iʻoi aku ka māmā.
No ka laweʻana i ke gula keʻokeʻo, ua hoʻohuiʻia ke gula maʻemaʻe i ka platinum, ka palladium , ke kālā, ka zinc a me ka nickel (ʻoiai ua pāpāʻia ka hopena ma nā'āina he nui e pili ana i ke olakino). ʻO kēia mau metala e hāʻawi ana i ka'ilika i keʻokeʻo keʻokeʻo. No laila, ua nui nāʻano likeʻole o keʻano he gula keʻokeʻo: 375 (ʻo ia hoʻi, 37.5% ke gula maikaʻi ma loko o ke kinikini), 500 (50%), 585 (58.5%), 750 (75%) a me 958 (95.8 %). No ka hanaʻana i nā mea maikaʻi,ʻo ia ka alloys 585 a me 750 hāhā, no ka mea, ua loaʻa iā lākou ka lakene maikaʻi loa ma waena o ka nui o ke kinona waiwai nui (e pili ana i ke kumukūʻai o ka huahana) a me nā mahele o nā mea'ē aʻe (e pili ana i kona ikaika a me ke kū'ēʻana).
He aha ka ho'āʻo maikaʻi loa no ka'ōmaʻa keʻokeʻo?
ʻO keʻano o ka nānāʻana i nā hiʻohiʻona keʻokeʻo keʻokeʻo keʻokeʻo keʻokeʻo ma waho o kaʻeha i hoʻokomoʻia i nā huahana mai ka'ōmaʻomaʻo a me ka'ōmaʻomaʻo. Akā me ka ho'ākākaʻana i kahiʻoi o ke gula'ōmaʻomaʻo, hiki i nā pilikia. ʻO ka meaʻoiaʻiʻo, ma ka nānā muaʻana, ua like ka nui o ke gula i ka hale hoʻonani,ʻo ka maikaʻi. ʻO ia hoʻi,ʻo ka hōʻailona 750 heʻoi muaʻoi aku ma mua o 585. Akāʻaʻole kēia ka manawa maʻamau.
