Emazingeni womtjhiso aphasi, izinga lokuthambisa liyancipha, okuthinta ukusebenza kuhle kokwakha. Lokha amazinga womtjhiso nawehla ngaphasi kwezinga lokutjhisa, amanzi atjhuguluka abe yiqhwa, akhule ngobukhulu, begodu athambekele ekubangeleni ukungaboni ngaso linye okufana nokugobhoza nokuqhekeka. Ngemva kobana amanzi ahwamuke, iinkhala zangaphakathi ziyakhula, okwenza bona kube nokuqina kwedaka.
Amandla wedaka athembele khulu ngezinga lokusabela nesikhathi sesimende namanzi. Lokha nakwakhiwa ngaphasi kwe-0°C, amanzi ayaqanda, begodu nanyana ukuthambisa kuba yi-exothermic reaction (okunikela amazinga womtjhiso wokuthambisa), ukusebenza kuhle kokuphendula kwesamente kusancipha. Lokha izinga lokutjhisa nalikhuphuka ngaphezu kwe-0°C, iqhwa liyancibilika, begodu ukuthambisa kuyathoma godu—kodwana umjikelezo lo unciphisa amandla wesimende.
