Ka nānā ʻana ma mua o ka mālama ʻana i ka wela o nā mea hoʻoheheʻe make

ʻO ka nānā ʻana ma muahoʻonā wela welaʻo ia ke kaʻina nānā mua o ka huahana i hoʻopau ʻia e like me ka mea i ʻōlelo ʻia ma kake kalaiwa anaʻāpana kiʻi a me ka hana kāleka no ka maikaʻi o ka ʻili a me nā ana o waho ma hope o ka pau ʻana o ke kaʻina hana forging. Pono ka nānā pono ʻana i nā ʻano penei:

① Pono ka helehelena me ka ʻole o nā māwae, nā ʻōpala, nā unahi oxide a me nā puʻupuʻu ma ka ʻili o ka mālama wela.
