Ngale kwesimende esimpunga esivamile kukhona usimende omhlophe, izinto zokwakha ezikhethekile ezithandwa ngombala wazo ohlanzekile kanye nokuguquguquka komklamo. Ubumhlophe bawo obuhlukile buvela ekukhethweni okuqinile kwezinto zokusetshenziswa—abakhiqizi basebenzisa i-limestone emsulwa kakhulu, ubumba lwe-kaolin, kanye ne-silica ene-iron oxide encane kanye nokunye ukungcola okubangela umbala.
Ukukhiqizwa kudinga ukunemba: uphethiloli ofana negesi yemvelo ugwema ukungcola, kuyilapho imishini yokugaya i-ceramic noma itshe ivimbela ukushintsha kombala wensimbi. Ngemva kokugaya cishe ngo-1450°C ukuze kwakheke i-clinker, i-gypsum iyangezwa ngaphambi kokugaya kahle ukuze kufezwe ubumhlophe obufunwayo, obubekwe ezingeni ezine.
Nakuba ifana nesamente elimpunga ngokwesakhiwo, ukusetshenziswa kwayo kuhlobisa ngendlela ethambile: kusukela ekumbozweni kwezakhiwo kanye naphansi e-terrazzo kuya eziqoshweni ezibaziweyo kanye nemikhiqizo yesamente enemibala. Iphinde ithuthukise ukusebenza kahle kwamandla ngokukhanya okukhanyayo futhi ivumela ukuhlanganiswa kombala okugqamile kwemiklamo eyenziwe ngokwezifiso. Inhlanganisela yesayensi nobuciko, isamente elimhlophe iyaqhubeka nokuphakamisa amandla okubukeka kwesakhiwo sesimanje.
