Hoʻomaʻemaʻe ʻia nā momi lana o ka hale hana mana ma o kekahi mau kaʻina hana, hiki ke hoʻomaʻemaʻe ʻia mai ka hale hana mana, no laila pehea e hiki ai ke hoʻomaʻemaʻe ʻia nā momi lana mai ka hale hana mana. Pono ʻoe i ka ʻenehana kiʻekiʻe? He aha nā kaʻina hana a me nā ʻano e pono e makaʻala ʻia
ʻO ka lehu lele o ka hale hana mana he ʻano koena pauka mai ka paila kinoea flue ma hope o ka puhi ʻana i ka lanahu wili. He ʻano mea pozzolanic artificial ia, ʻo ia hoʻi, he ʻano mea siliceous a aluminosilicate paha. He nui ka loli o ka hana o ka lehu lele, ʻaʻole pili wale i ke ʻano lanahu a me ke kumu lanahu, akā pili pū kekahi i ke ʻano o ka paila, nā kūlana hana a me ke ʻano hoʻokuʻu lehu. Ma ke ʻano laulā, i ka wā e wikiwiki ai ka wikiwiki o ka hoʻomaʻalili ʻana, ʻoi aku ka nui o ke aniani, ma ke ʻano ʻē, maʻalahi ke aniani e crystallize. Hiki ke ʻike ʻia ma ke ʻano o ka pae, ʻo ka lehu lele he hui pū ʻana o nā minelala crystalline a me nā minelala non crystalline, a he nui ka loli o kona ʻano mineral.
