E hoʻoheheʻe i ka potassium dichromate a i ʻole nā ​​kristal i loko o ka wai a hiki i 60 a 80 degere, a hoʻohui mālie i ka waikawa sulfuric i hoʻopaʻa ʻia me ka nui o 94% a lawa. E hoʻohui mālie a hoʻoulu. E hoʻohui a hiki i 1200 milliliters o ka potassium sulfate a hoʻoheheʻe loa paha, a e ʻike ʻia ka hopena he ʻulaʻula ʻeleʻele. I kēia manawa, hiki ke hoʻolalelale ʻia ka wikiwiki o ka hoʻohui ʻana i ka waikawa sulfuric i hoʻopaʻa ʻia a hiki i ka hoʻohui piha ʻia. Inā he mau kristal i hoʻoheheʻe ʻole ʻia ma hope o ka hoʻohui ʻana i ka waikawa sulfuric i hoʻopaʻa ʻia, hiki ke hoʻomehana ʻia a hiki i ka wā e hoʻoheheʻe ʻia ai. ʻO ka hana o ka hopena hoʻomaʻemaʻe, ʻo ia ka wehe ʻana i nā mea haumia maʻamau, ka momona, a me nā haumia ʻāpana metala ma ka paia o ka pahu kānana kila kila, a hiki iā ia ke pepehi pono i nā bacteria a me nā microorganism e ulu ana ma ka pahu kānana a hōʻino i ke kumu wela. Inā ua holoi ʻia ka mea kānana ma mua o ka alkaline, pono e holoi mua ʻia ka hopena alkaline, i ʻole e hoʻoulu ʻia nā waikawa momona a hoʻohaumia i ka mea kānana.
