Marka la barbar dhigo lebennada iska celinaya ee caadiga ah, lebennada dahaarka ee khafiifka ah ayaa miisaankoodu ka fudud yahay, daloollada yaryar ayaa si siman ugu qaybsan gudaha, waxayna leeyihiin sinnaansho sare. Sidaa darteed, waxay dammaanad qaadi kartaa kulayl yar in laga lumo gidaarka foornada, kharashka shidaalkana waa la dhimay si waafaqsan. Lebenka fudfudud waxa kale oo ay leeyihiin kaydinta kulaylka yar, markaa kululaynta iyo qaboojinta foornada lagu dhisay leben khafiifa waa dheereya, taas oo u oggolaanaysa waqtiyada foornada degdegga ah. Lebenka dahaarka kulaylka khafiifka ah ayaa ku habboon heerkulka kala duwan ee 900 ℃ ~ 1650 ℃.
Astaamahaleben dahaarka khafiifa
1. Dhaqdhaqaaqa kulaylka hooseeya, awoodda kulaylka hooseeya, nuxurka wasakhda hoose
2. Xoog sare, caabbinta shoogga kulaylka wanaagsan, caabbinta daxalka wanaagsan ee acid iyo jawiga alkali
3. Saxnaanta cabbirka sare
Codsiga lebennada dahaarka ee khafiifka ah
1. Foornada warshadeed ee kala duwan ee alaabta dahaarka ah ee kulul, sida: foornada annealing, foornada carbonization, foornada kululaynta, foornada kululaynta saliidda, foornada dildilaaca, rullaluistemadka, foornada tunnel, iwm.
2. Qalabka dahaarka ee foornooyinka kala duwan ee warshadaha
3. Dhimista foornada.
