1. Pena kiʻi
-Wehewehe: ʻO ka pena ka huaʻōlelo maʻamau no nā hana i hana ʻia e hana i kahi kiʻiʻoniʻoni me ka hoʻohana ʻana i ka pena no ka uhi ʻana i ka ʻili o kahi mea no ka pale a me ka nani, etc.
-Purpose: ʻO ke kumu o ka pena ʻana ʻaʻole wale no ka aesthetics, akā no ka pale ʻana a, no laila, ka hoʻomaikaʻi ʻana i ka maikaʻi o ka huahana.
1) Palekana: ʻO ka hapa nui o nā mea nui o nā kaʻa he mau papa kila, a i ka wā e hana ʻia ai kahi kaʻa me kahi pā kila ma ke ʻano he uhi, hoʻololi ia me ka wai a i ʻole ka oxygen i ka lewa e hoʻohua ai i ka ʻōpala. ʻO ke kumu nui o ka pena ʻana, ʻo ia ka pale ʻana i ka mea ma ka pale ʻana i kēlā ʻōpala (rust).
2) Hoʻonanea: ʻO ke ʻano o ke kaʻa he mau ʻano o nā ʻili a me nā laina e like me nā ʻāpana ʻekolu, nā ʻili palahalaha, nā ʻaoʻao curved, nā laina pololei, a me nā pihi. Ma ka pena ʻana i kēlā ʻano mea paʻakikī, hōʻike ia i ke ʻano o ke kala e kūlike me ke ʻano o ke kaʻa a hoʻomaikaʻi i ka nani o ke kaʻa i ka manawa like.
3) Hoʻomaikaʻi i ka mākeke: I kēia manawa, aia nā ʻano kaʻa like ʻole ma ka mākeke, akā i waena o lākou, i ka hoʻohālikelike ʻana i nā kaʻa me kahi ʻano hui like a me ka hana like, no ka laʻana, ʻoi aku ka maikaʻi o ka mea me ka pena kala ʻelua. piʻi ka waiwai e like me Ma kēia ʻano, ʻo ia kekahi o nā pahuhopu e hoʻāʻo e hoʻomaikaʻi i ka waiwai o ka huahana ma ka pena. Eia kekahi, koi ʻia ka lōʻihi o ka waho o nā kaʻa ma muli o nā loli kaiapuni. No ka laʻana, ke piʻi nei ka noi no nā pena hana e pale ai i ka hōʻino ʻana i ke kiʻi ʻoniʻoni i hoʻokumu ʻia e ka ua waikawa a me ka hoʻohaʻahaʻa ʻana o ka glossiness mua i hoʻokumu ʻia e nā pulu holoi kaʻa kaʻa e hoʻonui ai, e hoʻomaikaʻi ai i ka mākeke.Ho'ohana 'ia ka pena 'akomi a me ka pena lima ma muli o ka pono o ka uhi 'ana.
2. Hoʻohui ʻia o ka pena: Hoʻohui ʻia o ka pena ʻO ka pena he wai ʻeleʻele kahi e hui like ai nā ʻāpana ʻekolu o ka puaʻa, resin, a me ka solvent (puehu).
- Pigment: He pauda kala ʻaʻole e hoʻoheheʻe ʻia i loko o nā mea hoʻoheheʻe a i ʻole ka wai. ʻO ka ʻokoʻa mai nā wai kala ʻo ia ka hoʻopuehu ʻia e like me nā ʻāpana me ka hoʻoheheʻe ʻole ʻia i ka wai a i ʻole nā mea hoʻoheheʻe. ʻO ka nui o nā ʻāpana mai kekahi mau micrometers a i kekahi mau ʻumi micrometers. Eia kekahi, aia nā ʻano like ʻole, e like me ke ʻano pōʻai, ke ʻano lāʻau, ke ʻano nila, a me ke ʻano flaky. He pauda (powder) e hāʻawi i ka waihoʻoluʻu (mana kala) a me ka mana huna (ka hiki ke uhi a huna i ka ʻili o kahi mea ma ke ʻano opaque) i ke kiʻi uhi, a ʻelua ʻano: inorganic a me ka organik. Hoʻohana ʻia ka puaʻa), polishing, a me extender pigments e hoʻomaikaʻi i ka manaʻo o ka ʻāina. ʻO nā pena waihoʻoluʻu a ʻaʻole i kapa ʻia he akaka ma waena o nā pena, ke hoʻokaʻawale ʻia nā puaʻa mai nā ʻāpana o nā pena.
Hoʻohana ʻia ia e hāʻawi i ke kiʻi ʻoniʻoni i ʻoi aku ka luster.
1) Ka hana o ka puaʻa
* Nā puaʻa kala: hāʻawi kala, mana huna
