Imoduli ye-refractory ceramic fiber iwumkhiqizo omusha wolwelwesi oluphikisayo ukuze kwenziwe lula futhi kusheshiswe ukwakhiwa kwesithando somlilo kanye nokwenza ngcono ubuqotho bamalayini.Umkhiqizo, omhlophe qwa, usayizi ojwayelekile, ungalungiswa ngqo kubhawodi lesikhonkwane leshidi lensimbi yesithando somlilo, elinokufakwa kahle okungashi kanye nokushisa, okwandisa ubuqotho bokufakelwa kwesithando somlilo futhi kuthuthukise ubuchwepheshe bamalayini esithandweni somlilo.Izinga lokushisa layo lokuhlukanisa (Kusuka ku-1050°Cto 1600°C).
