ʻO Obsidian Starry Night, i kapa ʻia ʻo Obsidian Fireworks a i ʻole Flower Obsidian.

ʻO kahi hui hoʻohiwahiwa o ka obsidian ʻeleʻele me ka ʻākoʻakoʻa, kaʻaila, ka ʻulaʻula a me ka hau keʻokeʻo.

E kūʻai i ka pō hōkū obsidian maoli ma kā mākou hale kūʻai

aniani lua pele obsidian

ʻO ka Obsidian kahi aniani lua pele maoli i hana ʻia ma ke ʻano he pōhaku igneous kaomi.

Hoʻokumu ʻia ka Obsidian i ka wā e maʻalili wikiwiki ai ka pele i hoʻokuʻu ʻia mai ka lua pele me ka liʻiliʻi o ka ulu aniani. Loaʻa maʻamau i loko o nā kahe rhyolitic i kapa ʻia ʻo obsidian flows, kahi i haku ʻia ai ke kiʻekiʻe kiʻekiʻe o ka silica i ka viscosity kiʻekiʻe, a ma ka hoʻomaloʻo wikiwiki e hana ʻia ke aniani pele maoli.

ʻO ke kāohi ʻana o ka hoʻopuehu ʻātoma ma o kēia pele pili loa e wehewehe i ka nele o ka ulu aniani. ʻO ka obsidian he paʻakikī, palupalu a amorphous. No laila, haki me nā ʻaoʻao ʻoi. Ua hoʻohana ʻia ia i ka wā ma mua i ka hana ʻana i nā mea ʻoki a me nā mea paʻi, a ua hoʻohana ʻia nō hoʻi i ka hoʻokolohua ʻana e like me nā ʻili scalpel ʻokiʻoki.

Obsidian pō hōkū mai Mekiko.

Nā waiwai obsidian o ka pō hōkū

Hoʻokumu ʻia ka Obsidian mai ka pele paʻa wikiwiki, ʻo ia ke kumu kumu. Hiki ke hana 'o Obsidian i ka wā e ma'alili koke ai ka pele felsic ma nā lihi o ka pele a i 'ole ka lua pele, a i 'ole i ka wā e ma'alili ai ka pele i ka hui 'ana me ka wai a me ka ea. Hiki ke hoʻokumu ʻia ka obsidian i ka wā e maʻalili ai ka pele felsic ma ka ʻaoʻao o ka pā.

ʻO ka Obsidian ka like me ka mineral, akā ʻaʻole ia he mineral maoli no ka mea, e like me ke aniani, ʻaʻole ia he kristal. Eia kekahi, ʻano ʻokoʻa kona ʻano ʻano ʻaʻole hiki ke helu ʻia he mineral. I kekahi manawa ua kapa ʻia ʻo ia he mineraloids. ʻOiai he ʻeleʻele maʻamau ka obsidian i ka waihoʻoluʻu, e like me nā pōhaku kumu e like me ka basalt, ʻo ka haku mele ʻana o ka obsidian he waika loa.

Hoʻokumu ʻia ka Obsidian me ka silicon dioxide, maʻamau 70% a ʻoi aku paha. ʻO ka Granite a me ka rhyolite nā pōhaku crystalline o ke ʻano like. Ma muli o ka metastable o ka obsidian ma ka ili o ka Honua, ua lilo ke aniani i mau kristal kolakela maikaʻi; ʻaʻohe obsidian i ʻoi aku ma mua o ka Cretaceous i loaʻa.

Hoʻonui ʻia kēia hoʻololi o ka obsidian i mua o ka wai. ʻOiai he haʻahaʻa ka wai o ka obsidian hou, ʻoi aku ka liʻiliʻi ma mua o 1% ma ke kaumaha o ka wai, hoʻomaʻamaʻa mālie ʻia ma lalo o ka mana o ka wai lepo e hana i ka perlite.

Obsidian pō hōkū ma lalo o kahi microscope

ʻO ka pō hōkū obsidian kūlohelohe no ke kūʻai aku ma kā mākou hale kūʻai

Hana mākou i ka pō hōkū obsidian ma ke ʻano o nā apo mare, nā lei, nā apo pepeiao, nā kūpeʻe lima, nā pendants… E ʻoluʻolu e kelepona mai iā mākou no kahi ʻōlelo.
