Hangata re sebelisa lihlahisoa tse fapaneng tsa likhalase bophelong ba rona, joalo ka lifensetere tsa khalase, likhalase, mamati a thellang, joalo-joalo. Lihlahisoa tsa khalase li ntle ebile lia sebetsa.Botlolo ea khalase e entsoe ka lehlabathe la quartz e le thepa e ka sehloohong e tala, 'me lisebelisoa tse ling tse thusang li qhibiliha ka metsi ka mocheso o phahameng, ebe botlolo ea oli ea bohlokoa e tšeloa ka har'a hlobo, e pholile, e khaotsoe le ho halefa ho etsa botlolo ea khalase.Hangata libotlolo tsa khalase li na le letšoao le thata, 'me letšoao le lona le entsoe ka sebōpeho sa hlobo.Ho ea ka mokhoa oa ho etsa tlhahiso, ho bōptjoa ha libotlolo tsa khalase ho ka aroloa ka mefuta e meraro: ho fofa ka letsoho, ho phunya ka mechine le ho bōptjoa ha extrusion.A re shebeng ts'ebetso ea tlhahiso ea libotlolo tsa khalase.
Mokhoa oa ho hlahisa libotlolo tsa khalase:
1. Pele ho ts'ebetso ea lisebelisoa tse tala.Hlakola lisebelisoa tse tala tse ngata (lehlabathe la quartz, soda ash, limestone, feldspar, joalo-joalo) ho omisa lisebelisoa tse tala tse metsi, le ho tlosa tšepe ho thepa e nang le tšepe ho netefatsa boleng ba khalase.
2. Ho lokisetsa sehlopha.
3. Ho qhibiliha.Thepa ea batch ea khalase e futhumatsoa ka mocheso o phahameng (1550 ~ 1600 likhato) ka sebōping sa letamo kapa sebōpi sa letamo ho etsa khalase ea metsi e sa tšoaneng, e se nang bubble e finyellang litlhoko tsa ho bōptjoa.
4. Ho theha.Beha khalase ea metsi ka har'a hlobo ho etsa sehlahisoa sa khalase sa sebopeho se hlokahalang.Ka kakaretso, preform e thehoa pele, ebe preform e thehoa 'meleng oa botlolo.
5. Kalafo ea mocheso.Ka annealing, quenching le mekhoa e meng, khatello ea ka hare, karohano ea karolo kapa crystallization ea khalase e hloekisoa kapa e hlahisoa, 'me boemo ba sebopeho sa khalase bo fetoloa.
