Iglasi yeBorosilicateluhlobo lwempahla yeglasi enomxholo ophezulu weboron, omelwe ziimveliso ezahlukeneyo ezivela kubavelisi abahlukeneyo.Phakathi kwazo, i-Schott Glass's Borofloat33® yiglasi ye-silica eyaziwayo ephezulu, ene-80% yesilicon dioxide kunye ne-13% ye-boron oxide.Ngaphandle kwe-Schott's Borofloat33®, kukho ezinye izinto zeglasi ezine-boron kwimarike, njenge-Corning's Pyrex (7740), i-Eagle series, i-Duran®, i-AF32, njl.
Ngokusekwe kwii-oxide zentsimbi ezahlukeneyo,iglasi ye-silica ephezuluinokwahlulwa ibe ngamacandelo amabini: i-alkali-equlethe i-silica ephezulu (umzekelo, i-Pyrex, i-Borofloat33®, i-Supremax®, i-Duran®) kunye ne-alkali-free high-borate silica (kuquka uchungechunge lwe-Eagle, i-AF32).Ngokwee-coefficients ezahlukeneyo zokwandiswa kwe-thermal, i-alkali-equkethe i-silica glass high-borate ingaphinda ihlelwe kwiindidi ezintathu: 2.6, 3.3, kunye ne-4.0.Phakathi kwazo, iglasi ene-coefficient yokwandiswa kwe-thermal ye-2.6 ine-coefficient ephantsi kunye nokumelana nobushushu obungcono, okwenza ukuba ifanelekele njengengxenye yendawo.iglasi ye-borosilicate.Ngakolunye uhlangothi, iglasi ene-coefficient yokwandiswa kwe-thermal ye-4.0 isetyenziselwa ukusetyenziswa kokumelana nomlilo kwaye ineempawu ezintle zokumelana nomlilo emva kokuqina.Uhlobo oluqhelekileyo olusetyenziswayo lulo olunomlinganiselo wokwandisa i-thermal ye-3.3.
