Odayi besibabulesezineminyaka engaphezu kwekhulu zikhona.Odayi bokuqala besulfure bakhiqizwa uCroissant noBretonniere ngo-1873. Basebenzisa izinto eziqukethe imicu ephilayo, njengama-wood chips, umquba, ubran, ukotini odoti, kanye ne-Waste Paper njll., etholwe ngokushisa i-alkali sulfide ne-polysulfide alkali.Lo dayi we-hygroscopic onombala omnyama nonuka kabi unokwakheka okungagxilile kubhavu we-alkali futhi uncibilika kalula emanzini.Lapho ukotini udaywa endaweni yokugeza ye-alkali kanye nokugeza kwesibabule, kungatholakala odayi abaluhlaza.Uma kuvezwe emoyeni noma kufakwe i-oxidized amakhemikhali ngesisombululo se-dichromate sokulungiswa kombala, indwangu kakotini ingaba nsundu.Ngenxa yokuthi laba badayi banezakhiwo ezinhle kakhulu zokudaya namanani aphansi, bangasetshenziswa embonini yokudaya ukotini.
Ngo-1893, u-R. Vikal wancibilikisa i-p-aminophenol nge-sodium sulfide nesibabule ukuze akhiqize odayi abamnyama besibabule.Waphinde wathola ukuthi i-eutectic yezinto ezithile eziphuma ku-benzene ne-naphthalene ezinesulfure ne-sodium sulfide ingakhiqiza odayi abahlukahlukene abamnyama.Kusukela ngaleso sikhathi, abantu baye benza odayi abaluhlaza besulfure, odayi ababomvu beSulfur kanye nodayi abaluhlaza okwesibhakabhaka ngalesi sisekelo.Ngesikhathi esifanayo, indlela yokulungiselela kanye nenqubo yokudaya nayo ithuthukiswe kakhulu.Odayi besulfure abancibilika emanzini, odayi besulfure abawuketshezi kanye nodayi besulfure abangayingcolisi imvelo baye bavela ngokulandelana, okwenza odayi besibabule bathuthukiswe ngamandla.
Odayi besulfure bangomunye odayi abasetshenziswa kakhulu.Ngokwemibiko, ukukhiqizwa kukadayi wesulfure emhlabeni wonke kufinyelela kumakhulu ezinkulungwane zamathani, futhi uhlobo olubaluleke kakhulu olumnyama oluyisulfure.Ukukhishwa kwe-sulphur black account ku-75% -85% wesamba sokukhishwa kodayi besulfure.Ngenxa yokwakheka kwayo okulula, izindleko eziphansi, ukushesha okuhle, nokungakhathaleli umdlavuza, ithandwa abakhiqizi abahlukahlukene bokunyathelisa nokudaya.Isetshenziswa kakhulu ekudayeni ukotini neminye imicu ye-cellulose, uchungechunge olumnyama noluhlaza okwesibhakabhaka lusetshenziswa kakhulu.
