Mukubika tii mazuva ese, murabhoritari, kana{0}}tembiricha yemumaindasitiri, kupisa{1}}makapu egirazi asingadzivirirwe ndiyo sarudzo inosarirwa nekuda kwekufambiswa kwechiedza kwakanakisa uye kusimba kwemakemikari. Zvisineyi, kunaka kwezvigadzirwa pamusika kunosiyana zvakanyanya, uye zvimwe zvigadzirwa zvakachipa zvinonyepa kuti "zvisingadziye-," izvo zvinogona kukonzera kuputsika nyore. Kuziva nezvemapoinzi ekutenga anotevera kunogona kukubatsira kuti udzivise ngozi uye usarudze-zvigadzirwa zvemhando yepamusoro zvinozadzisa zvaunoda.
Hunhu hwakakosha pa-kuramba tembiricha; koshesa girazi reborosilicate rakakwirira. Girazi rerudzi urwu rine 12% ~ 15% boron oxide, rine kuwedzera kwekushisa kwe 3.3×10⁻⁶/degree chete, uye rinokwanisa kumira kushanduka kwekamwe kamwe tembiricha kubva -20 madhigirii kusvika 150 madhigirii, nekuramba tembiricha kuramba kunosvika 300~500 madhigirii, zvichiita kuti ive sarudzo yakanaka yekushandisa pamba. Ngwarira kutevedzera zvakagadzirwa nesoda{14}}girazi reraimu; tembiricha yayo kuramba isingasviki 80 dhigirii, uye inotsemuka nyore kana yaiswa mumvura iri kufashaira. Inowanzo kushambadzwa zvenhema se "girazi rinodzivirira kupisa" nevatengesi vasina kunaka.
Zvinyorwa zvekugadzira zvinotarisa zvakananga kuchengeteka uye kusimba. Muviri wemukombe unofanirwa kunge usina musono, -chimedu dhizaini kudzivirira kuungana kwetsvina uye kuona chimiro chakagadzikana. Nzvimbo yacho inofanira kuva yakatsetseka, isina mabhuru uye kuputika. Rimu rinofanirwa kunge riri laser-rakachekwa kuita denderedzwa risingakwenye muromo. Ukobvu hwepasi hunofanirwa kunge huine 5mm, zvakanaka ne-isina kutsvedza silikoni mhete kuti iwedzere kuputika uye kuderedza njodzi yekupeta. Kune zvigadzirwa zvakadhindwa, madziro emukati anofanirwa kuve akajeka, uye kunze kwemadziro kudhinda kunofanirwa kunge kuri FDA kana LFGB yakasimbiswa kudzivirira kubuda kwesimbi inorema senge lead uye cadmium pakupisa kwakanyanya.
Madiro echigadzirwa anofanirwa kunyatsoenderana nemamiriro ekushandiswa. Zvekushandisa kumba, sarudza kapu mbiri-yakavakirwa insulated yakakwirira borosilicate yekubikisa tii nekofi; mukaha wemhepo weKupfuura kana kuenzana ne5mm zvinodzivirira kudzivirira kupisa. Kune marongero emurabhoritari, tungamira vakapedza kudzidza yakakwira borosilicate glassware kuti ive nechokwadi chedimensional kurongeka uye kugadzikana kwemakemikari. Pakukwirisa-tembiricha yakadai semahwindo emuindasitiri, sarudza zvigadzirwa zvine ukobvu kwakakodzera zvichienderana nezvinodiwa tembiricha; semuenzaniso, girazi requartz rinoshandiswa munzvimbo dze1200℃rinoda ukobvu hweHukuru pane kana kuenzana ne15mm. Uyewo, teerera kune chivharo zvinhu; chikafu-giredhi silicone inoshingirira tembiricha kubva -40 ~ 230 dhigirii, inopa kuchengetedzwa kwepamusoro kana ichienzaniswa neakajairwa epurasitiki.
