Dhalada borosilicatewaa nooc ka mid ah walxaha galaaska oo leh boron sare, oo ay matalaan alaabooyin kala duwan oo ka soo jeeda warshado kala duwan.Waxaa ka mid ah, Schott Glass's Borofloat33® waa galaas silica-borate-sare ah oo caan ah, oo leh qiyaastii 80% silicon dioxide iyo 13% boron oxide.Ka sokow Schott's Borofloat33®, waxaa jira agab kale oo boron-ku jira suuqa, sida Corning's Pyrex (7740), taxanaha Eagle, Duran®, AF32, iwm.
Iyada oo ku saleysan oksaydhyada birta ee kala duwan,galaas silica borate sarewaxa loo qaybin karaa laba qaybood: alkali-ka kooban silica-borate sare (tusaale, Pyrex, Borofloat33®, Supremax®, Duran®) iyo silica-borate-sare-free alkali (ay ku jiraan taxanaha Eagle, AF32).Sida laga soo xigtay isbahaysiga kala duwan ee balaadhinta kulaylka, alkali-ka kooban muraayadda silica-borate sare waxaa loo sii kala saari karaa saddex nooc: 2.6, 3.3, iyo 4.0.Waxaa ka mid ah, muraayadda leh koronto balaadhinta kulaylka ee 2.6 waxay leedahay isugeyn hoose iyo iska caabin heerkul ka wanaagsan, taasoo ka dhigaysa mid ku habboon beddelka qayb ahaangalaas borosilicate.Dhanka kale, galaaska leh isugeynta balaadhinta kulaylka ee 4.0 ayaa inta badan loo isticmaalaa codsiyada u adkaysta dabka waxayna leedahay sifooyin u adkaysta dabka ka dib marka la adkeeyo.Nooca ugu badan ee la isticmaalo waa kan leh iskudar balaadhinta kulaylka ee 3.3.

Marka la soo koobo, marka loo eego galaaska lime soodhaha,galaas boroslicatewaxay leedahay degganaansho kulayl oo wanaagsan, xasilloonida kiimikada, gudbinta iftiinka, iyo sifooyinka korantada.Natiijo ahaan, waxay leedahay faa'iidooyin ay ka mid yihiin iska caabbinta nabaad-guurka kiimikaad, shoogga kulaylka, waxqabadka farsamada oo aad u wanaagsan, heerkulka hawlgalka oo sarreeya, iyo adayg sare.Sidaa darteed, waxaa sidoo kale loo yaqaanmuraayadda kulaylka u adkaysata, galaas shoog u adkaysta kulaylka, dhalo heerkul sare leh, waxaana caadi ahaan loo isticmaalaa muraayad gaar ah oo dabka u adkaysata.Waxaa si weyn looga dabaqaa warshadaha sida tamarta qorraxda, kiimikaad, baakadaha dawooyinka, optoelectronics, iyo farshaxanka qurxinta.
