Ma ka pae ʻenehana, ua waiwai nā kumu o nā mea maka no ka hana ʻana i nā pōhaku lepo ʻole i hana ʻia e ka mīkini brick ʻaʻole i puhi ʻia, a i kēia manawa ke hāʻawi nei ka hoʻonui ʻana i ka ʻōpala hana i kahi hōʻoiaʻiʻo pono no nā pōhaku i puhi ʻole ʻia. ʻO ka ʻenehana a me ke kaʻina hana o Honcha non fired brick machine aia ma ka pae alakaʻi ma Kina. E like me kā mākou e ʻike ai, pili ka hana o ka huahana i nā ʻano o nā mea maka a me nā mīkini i hana ʻia. E like me ka nānā ʻana i ka hale nānā o ka pā aupuni a me ka hale, ʻoi aku ka kiʻekiʻe o ka hana ʻana o ka pōhaku i hana ʻia e ka mīkini palolo ʻulaʻula ma mua o ka pōhaku ʻulaʻula kahiko, ʻoi aku ka maikaʻi a me ka hoʻoheheʻe ʻana i ka wai ma mua o ka pōhaku lepo maʻamau, a ʻoi aku ka liʻiliʻi o ka maloʻo maloʻo a me ka conductivity thermal ma mua o nā huahana paʻa maʻamau. I ka pōkole, hōʻike ʻia nā ʻikepili hoʻāʻo ʻoihana maoli e ʻoi aku ka maikaʻi o ka hana compressive structural o nā pōhaku i puhi ʻole ʻia ma mua o ka pōhaku ʻulaʻula kahiko. Hiki iā ia ke pale i ka hoʻāʻo o ka mōʻaukala a me ka manawa, a he koʻikoʻi maikaʻi ia i ka mālama ʻana i ke kaiapuni.
