Ke kohoʻana o kahi mea no ka makeʻana ma luna o kekahi mau kumu nui e pili ana i kekahi mau kumu, mevery point, a me ke kumu kūloko, a me ke kumu. Hiki paha i ka mea ke hoʻopilikia i ka hoʻolālā o ka'āpana. No ka laʻana,ʻo ka hoʻohanaʻana o ka zinc,ʻo ia kahi metala momona loa, hiki iā ia keʻae no nā pā pōhaku a me kahiʻoi aku ka maikaʻi ma mua o nā alloys'ē aʻe. ʻAʻole e hoʻoholo waleʻia nā mea i nā waiwai o ka mea i kauʻia, akā hoʻopau pū kekahi i ka mīkini a me nā mea hana. Nā mea hana me nā haʻahaʻa haʻahaʻa haʻahaʻa, e like me zinc alloys, hiki ke make i ka mīkini kuke wela. Eia nō naʻe, nā mea waiwai me ke kiʻekiʻe haʻahaʻa kiʻekiʻe, e like me Alaminum a me nā molluina a me nā keleawe, pono ke hoʻohana i ka mīkini hana kīwī. Hoʻopili ka mahana o ka mīkini i keʻano o ka mea hana, e like me ke kiʻekiʻe kiʻekiʻe e loaʻa ai kahi hopena kiʻekiʻe loa i ke ola o nā make.
