Waqtiga foornada waa inuu ahaadaa 200 ° C ilaa 600 ° C afar saacadood. Marka la isticmaalayo, heerkulka foornada waa in uusan dhaafin heerkulka la qiimeeyay, si uusan u gubin walxaha kuleylka. Waa mamnuuc in foornada lagu shubo dareere kala duwan iyo biraha si fudud u milmi kara. Foornada maafku waxay ku shaqeysaa heerkul ka hooseeya 50 ℃ heer kulka sare, iyo siliga foornada ayaa leh nolol dheer.
