Tsebiso:
1. Electrode e lokela ho besoa hora e le 'ngoe mochesong o ka bang 350℃ pele ho ts'ebetso ea ho tjheseletsa;
2. Ho bohlokoa ho hlwekisa mafome, sekala sa oli, metsi le litšila likarolong tsa ho tjheseletsa pele ho tjheseletsa;
3. Sebelisa ts'ebetso e khutšoanyane ea arc ha u tjheseletsa. Tsela e moqotetsane ea ho tjheseletsa e loketse.
