Ichi chigadzirwa rudzi rwepamhepo rwakasanganiswa nemvura sekusimudzira mumiririri, izvo zvinonyanya kuongororwa kuti kuomarara pombi yekugadzira mapapiro ekupisa. Iyo inoshandiswa zvakanyanya mumapipi edenga, liquefied yakasikwa gasi runomhanya pombi, mapepa emafuta uye mamwe minda. Hunhu hwakateedzerwa:
.
(2) kupisa kwakanyanya-kuramba-kuramba, wakamira wakareba muna 150 ℃
(3) yakanakisa yakadzika tembiricha yakaderera kugadzikana
