ʻO ka pōhaku Volcanic Pumice (ʻike ʻia ʻo pumice a i ʻole basalt porous) kahi ʻano o nā mea pale o ka kaiapuni hana. He pōhaku porous waiwai nui ia i hana ʻia e ke aniani lua pele, nā minelala a me nā huʻa ma hope o ka luaʻi pele. Aia i loko o ka pōhaku lua pele he mau minelala a me nā kumumea kumuwaiwai, e like me ka sodium, magnesium, aluminika, silikone, calcium, titanium, manganese, hao, nickel, cobalt a me molybdenum. Loaʻa iā ia ka nalu magnetikona infrared mamao loa me ka ʻole o ka pāhawewe, Ma hope o nā makahiki he mau makahiki, ua ʻike ka poʻe i kona waiwai he nui a nui aku. I kēia manawa ua hoʻolōʻihi ʻia i nā māla o ke kūkulu ʻana, ka mālama wai, ka wili ʻana, nā mea kānana, nā lanahu barbecue, ka mālama ʻana i ka māla, ka mahi ʻana i ka lepo ʻaʻohe, nā huahana kāhiko a pēlā aku. He mea hiki ʻole ke hoʻololi ʻia i nā ʻano a pau o ke ola! ʻO ka hoʻōla pōhaku wela kahi ʻano pōhaku pōhaku, kahi e hoʻohana ai i nā pōhaku pele i wela e lawe i ka ikehu maikaʻi ʻole o ke kino o ke kanaka, e kōkua i ke kino o ke kanaka e hoʻopau i nā mea make a hāpai i ka metabolism kanaka.
