Hiki ke palaki ʻia ka ʻaoʻao ʻaoʻao piha a i ʻole ʻāpana ʻāpana. Hiki ke kiʻi ʻia e ka mīkini a i ʻole ka huki lima (ʻo ke ʻano o ka siliki lima lima maoli, akā ʻaʻole maʻamau).

ʻO nā kāleka kila kila i hoʻopaʻa ʻia maʻamau he gula rose, kālā, kālā kahiko, ʻeleʻele pū kala a pēlā aku.

Loaʻa i nā kāleka kūlana kiʻekiʻe nā ʻaoʻao maʻemaʻe, maʻemaʻe a maʻemaʻe hoʻi, a me nā kaha kāhili. Hiki ke kahakaha ʻia ka ʻili o ke kāleka kiʻi no ka hoʻokō ʻana i nā kaʻina hana e like me nā kumu hollow, concave a convex kikokikona, a me nā ʻano kala.

Kāleka kila kila maoli, ʻo ke kala hope o ke kāleka he kila kila, ʻike ʻia ke kumu ma ke kālai ʻana, a ʻike ʻia ka ʻike ma ka paʻi ʻana. He nani a he lokomaikaʻi ka huahana i hoʻopau ʻia, a kaulana loa kēia hana ma ka honua. Hiki ke kahakaha ʻia ke kumu hoʻohālike (laser engraving effect), hollowed out, a hiki ke paʻi ʻia i ke kala.

ʻO ke kumu i loaʻa ai i ke kila kila maikaʻi loa ka pale ʻana i ka corrosion no ka mea hiki ke hoʻokumu ʻia kahi kiʻiʻoniʻoni pale lahilahi a maopopo ma luna o kona ʻili. No laila, ʻoiai me ka pale ʻole o ka uhi ʻana, hiki i ke kāleka kila kila ke mālama i kona kala hina hina, ʻo ia hoʻi, ke kala maoli o ke kila kila no ka manawa lōʻihi.

Ke hana ʻia ke kala kila kila i kahi kāleka metala, i mea e hāʻawi ai i ka ʻāpana kila kila kūikawā i ke kino a me nā waiwai kemika (i ka wā e hana ai i kahi kāleka metala, ua manaʻo nui ʻia ia mai nā koi o ka nani a me ka olinolino) pinepine electroplating i kekahi metala. ka uhi e hoʻokō i nā koi. A hiki i kēia mau pale metala ke hāʻawi wale aku i ke kāleka kila kila i nā kala metala like ʻole.

Kāleka kila kuhiliʻole kala e pili ana i ka mālama ʻana i ka ʻili kūikawā, ka electroplating kala, i ʻoi aku ka nui o ke kala kāleka. Hiki iā ia ke electroplated hoʻokahi kala a i ʻole ʻelua kala like. Ma lalo o nā kūlana maʻamau, hiki iā ʻoe ke hana i ke gula rose, ke gula ʻeleʻele, ke kala pū, ka ʻeleʻele matte, ka poni matte, ka uliuli matte, ʻeleʻele + gula, ʻeleʻele + kālā, kālā + gula, gula + kālā a pēlā aku. ʻO ka lua, hiki iā ʻoe ke hana i ka hopena aniani, ka hopena polishing, matte surface, shading ʻokoʻa, etc.
