Amaphuzu alandelayo kufanele futhi anakwe ngesikhathi ukusetshenziswa isithando somlilo:

1. Indawo yokusebenza ayidingi izinto ezivuthayo, eziqhumayo namagesi agqwalayo;

2. Akuvunyelwe ukuthela ngokuqondile uketshezi oluhlukahlukene nezinsimbi ezincibilikisiwe esithandweni, futhi ugcine isithando somlilo sihlanzekile. Lapho isetshenziswa, izinga lokushisa lomlilo ngeke lidlule izinga lokushisa eliphezulu lesithando somlilo, futhi ngeke lisebenze isikhathi eside ekushiseni okulinganiselwe;

3. Umnyango wesithando somlilo kufanele uvalwe kancane futhi uvule ngesikhathi sokusetshenziswa ukuvimbela ukulimala ezingxenyeni. Ngesikhathi esifanayo, ama-crucible tongs kufanele aphathwe ngobumnene lapho ethatha amasampula ukuze kuqinisekiswe ukuphepha futhi agweme ukulimala esithandweni;

4. Ungavuli umnyango wesithando somlilo ngemuva kokuba izinga lokushisa lidlule ama-degrees angu-600, ulinde ukushisa esithandweni ukuze kuphole ngaphambi kokuvula umnyango wesithando somlilo;

5. Ngemva kokuqedwa kokuhlolwa, isampula iyahoxiswa ekushisiseni futhi amandla ayavalwa. Lapho ubeka isampula esithandweni somlilo, umnyango wesithando somlilo kufanele uvulwe kuqala. Ngemva kokuba isampula selipholile phansi, isampula kufanele iboshwe ngokucophelela ukuvimbela ukusha;

1. I-crucible eshisayo kufanele idluliselwe ku-desiccator ukuze iphole.
