Hanyar hazo kuma ana kiranta hanyar rigar, kuma manyan albarkatun ƙasa sune yashi quartz, soda ash, masana'antar hydrochloric acid ko sulfuric acid ko nitric acid ko carbon dioxide. Hanyar hanya ita ce gabaɗaya: na farko da amfani da man fetur ko gawayi mai inganci a babban zafin jiki na ma'adini yashi da soda ash don samar da gilashin ruwa na masana'antu, gilashin ruwa na masana'antu an shirya shi a cikin wani nau'i na bayani mai tsarma, sa'an nan kuma a karkashin wasu yanayi don ƙara wasu acid, don haka silica ya zubar da ruwa, sannan bayan tsaftacewa, tacewa, bushewa (bushewa ko fesa), farin carbon, don samar da samfurin. An raba hanyar hazo zuwa hanyar acid, hanyar sol, hanyar carbonization da takamaiman hanyoyi daban-daban.
(1) Hanyar acid
Gabaɗaya, hanyar acid shine amsawa tare da silicate mai soluble da sulfuric acid (ko wasu acid), lokacin da ruwan amsa ya kai wani ƙima, dakatar da halayen acid ɗin, tsufa, sannan tace a wanke da ruwa akai-akai, cire Na2S04, aika bushe, niƙa don samun samfurin.
(2) Hanyar Sol
Ana la'akari da wannan hanyar hanya mafi kyau, amma tsari ya fi rikitarwa fiye da hanyar acid, kuma abubuwan da ake bukata na kula da yanayin sun fi girma. Na farko, hydrochloric acid da sodium silicate suna mayar da martani don samar da wani taro na dilute sol, a ƙarƙashin yanayin zafi kadan da motsawa, ana ƙara maganin sodium silicate a cikin sol ɗin da aka shirya, kuma an ƙara wani adadin NaC1 don amsa pH = 7 ~ 8, kuma darajar H ana kiyaye shi tare da alkaline regulator, adana zafi da tsufa, sannan a cire chlorine, sannan a cire shi.
(3) Hanyar Carbonization
A cikin wannan hanyar, iskar carbon dioxide yana carbonized ta hanyar silicate mai narkewa don samar da Si02 da aka haɗe da sodium carbonate. Bayan an gama amsawa, an riga an tace samfurin, kuma an cire Na2C03 ta hanyar maganin ruwa na acid, sannan a tace, bushe, niƙa da kuma kunshe.
