Amagwiritsidwa ntchito kwambiri mu mafuta, mankhwala, feteleza, gasi ndi mafakitale oteteza zachilengedwe, monga chothandizira mu riyakitala kuphimba zinthu zothandizira ndi kulongedza nsanja. Ili ndi kutentha kwakukulu komanso kuthamanga kwambiri, kuchuluka kwaibodi ndikotsika, mawonekedwe amomwe ntchito zamagetsi zimakhazikika. Titha kupirira kukokoloka kwa asidi, soda ndi zinthu zina zosungunulira, ndipo zimatha kupirira pakupanga kusintha kwa kutentha. Ntchito yake yayikulu ndikuwonjezera gasi kapena magawidwe amadzi, kuthandizira ndi chitetezo sichinthu chachikulu chothandizira.
