Iglasi ye-borosilicate ephezulu(ekwaziwa ngokuba yiglasi eqinileyo), ibonakaliswa kukusetyenziswa kweglasi ukuqhuba umbane kumaqondo obushushu aphezulu. Iglasi iyanyibilikiswa ngokufudumeza ngaphakathi kweglasi kwaye icutshungulwe ziinkqubo zemveliso eziphambili.
I-coefficient ukuya kulwandiso lobushushu yi (3.3±0.1)x10-6/K, ekwaziwa ngokuba yi "borosilicate glass 3.3". Yiglasi ekhethekileyo enesantya esiphantsi sokwandiswa, ukumelana nobushushu obuphezulu, amandla aphezulu, ubulukhuni obuphezulu, ukukhanya okuphezulu
ukuhanjiswa kunye nozinzo oluphezulu lweekhemikhali. Ngenxa yokusebenza kwayo okugqwesileyo, isetyenziswa kakhulu kumandla elanga, kushishino lweekhemikhali, ekupakisheni amayeza, kumthombo wokukhanya kombane, ubucwebe bobugcisa kunye neminye imboni.
