Loaʻa pololei ke one kala maoli mai ka Honua mai. Loaʻa ia mai nā pōhaku a me nā minelala i loaʻa nā pigments kūlohelohe. ʻO ka hao oxide kekahi o nā mea hoʻoluʻu kūlohelohe maʻamau, nona ke kuleana no nā aka ʻulaʻula, ʻalani, a me ka ʻeleʻele i ʻike ʻia i nā one kala maoli he nui. No ka laʻana, ʻo nā kala ʻulaʻula-ʻeleʻele o kekahi mau one wao nahele he hopena ia o ka nui o ka hao oxide. Hiki i ka manganese ke hoʻokomo i nā leo ʻeleʻele a poni paha, ʻoiai hiki i nā hui keleawe ke hāʻawi i nā kala ʻōmaʻomaʻo a me ka uliuli. Hoʻomaka ka unuhi ʻana o ke one kala maoli me nā hana eli ma nā lua pōhaku a i ʻole nā ​​​​moku muliwai kahi i loaʻa ai kēia mau waihona pigmented. Ke ʻeli ʻia, hele ka mea maka i kahi moʻo o nā ʻanuʻu hana. Hoʻopau ka kuʻi ʻana i nā pōhaku nui i nā ʻāpana liʻiliʻi, a ukali ʻia e ka sieving e hoʻokaʻawale i ke one i nā nui palaoa like ʻole. A laila hana ʻia ka holoi ʻana e wehe i nā haumia e like me ka lepo, ka lepo, a me nā ʻāpana ʻē aʻe i makemake ʻole ʻia, e hōʻoia ana he kiʻekiʻe ke kiʻekiʻe o ka maʻemaʻe o ke one a me ka ikaika o ke kala i makemake ʻia.

ʻO ke one kala artificial, i ka hoʻohālikelike ʻana, hana ʻia ma o nā kaʻina hana i hana ʻia e ke kanaka. ʻO ka maʻamau, ʻo kahi mea kumu, pinepine ke one quartz ma muli o kona nui, paʻakikī, a me ke kala kūlike ʻole, e lawelawe ana ma ke ʻano he kumu. Hoʻohana ʻia nā ʻano hana pigmentation holomua e uhi a hoʻoluʻu paha i nā ʻāpana one quartz. Hoʻohana nā mea hana i nā pigments kiʻekiʻe a me nā mea hoʻopili pololei e hōʻoia i ka pili pono ʻana o ke kala i nā ʻāpana one. Hiki i nā ʻano uhi kūikawā ke hana i kahi papa kala like a lōʻihi, e ʻae ana i kahi ākea o nā kala i paʻakikī ke loaʻa ma ke ʻano maoli. Ma o ka kaohi pono ʻana i ke kaʻina hana hana, hiki i ke one kala artificial ke hoʻokō i ka maikaʻi o ke kala like a me ka hoʻolaha nui o nā ʻāpana, e hoʻokō ana i nā koi koʻikoʻi o nā ʻoihana like ʻole.
