1) Ukushisa kokusetshenziswa okuqhubekayo kungafinyelela ku-1000 ℃, futhi izinga lokushisa lokusetshenziswa kwesikhashana lingafinyelela ku-1260 ℃;
2) Inokumelana okuhle nokugqwala kwe-asidi ne-alkali kanye nekhono lokumelana nokugqwala kwensimbi encibilikisiwe njenge-aluminium ne-zinc;
I-3) Amandla amahle okushisa aphezulu nokusebenza kokushisa (sicela ubheke izinkomba zomzimba namakhemikhali);
4) Uchungechunge lwemikhiqizo efana nendwangu ye-ceramic fibre, itheyiphu, kanye nokupakishwa okuqiniswe ngemicu ye-alkali yengilazi ye-alkali enefayibha yengilazi ephezulu inezinga eliphezulu lokufakwa kukagesi kanye nokufakwa kukagesi okunezinga eliphezulu lokushisa kunemicu yengilazi;.
5) Ayinabuthi, ayinabungozi, futhi ayinaphunga.
