Kapu yagalasi yozungulira, yowongoka{0}}yopangidwa ndi galasi lapamwamba la borosilicate, lomwe limatha kupirira kutentha ndipo limapirira kusintha kwa kutentha. Sikophweka kusweka mutadzazidwa ndi madzi oundana kapena zakumwa zotentha. Panthawi imodzimodziyo, zinthuzo zimakhala zotetezeka komanso zopanda fungo, ndipo sizingagwirizane ndi zakumwa. Itha kugwiritsidwa ntchito moyenera kusunga zakumwa zosiyanasiyana monga khofi, mkaka, ndi madzi.
Makapu ozungulira, owongoka{0}}a m'mbali awa amakhala ndi mawonekedwe ozungulira, ndipo mphamvu yake imatha kusinthidwa kuti ikwaniritse zosowa zosiyanasiyana zamakasitomala. Kukula kwa kapu kumayendetsedwa ndi 2mm kokha, kuwonetsetsa kuwonekera komanso kulimba. Poyerekeza ndi makapu ang'onoang'ono agalasi, amapereka kukana kwamphamvu kwamphamvu, kumapangitsa kuti asamaphwanyike pang'onopang'ono komanso kugogoda pakugwiritsa ntchito tsiku ndi tsiku.
Mphepete mwa kapuyo imapindidwa bwino ndikupukutidwa, zomwe zimapangitsa kuti -ikhale yosalala, yosalala, yosalala, yofewa pokhudza kukhudza, kupewetsa kusamvana komwe kumachitika nthawi zambiri ndi timiyala taonda. Mphepete mwachitsulo imapangitsanso kuti chikhocho chikhale cholimba, kuteteza kuphulika pakapita nthawi. Pansi pakenso ndi yokhuthala, yophwanyika, ndipo imapereka kulemera kokhazikika, kuonetsetsa kuti pamakhala bata pa malo athyathyathya monga ma tablets ndi kuchepetsa chiopsezo cha kutaya.
Magalasi osalala, osasinthika, owoneka bwino amangowonetsa bwino mtundu ndi kugwirizana kwa zakumwa komanso kumapangitsa kuti kuyeretsa kukhale kosavuta: mutatha kugwiritsa ntchito tsiku ndi tsiku, kutsuka kosavuta ndi madzi kumachotsa zotsalira zilizonse. Palibe chovuta-kufikira{2}}kufikira madera monga miponje kapena mapatani omwe amatsekera dothi, komanso ndi chitetezo chotsukira mbale.
Galasi yozungulira, yowongoka{0}}yopangidwa ndi galasi la lead- laulere, lomwe limakwaniritsa zakudya-zoyenderana bwino. Sichidzawononga zinthu zovulaza ngakhale mutagwiritsa ntchito nthawi yayitali-, kuonetsetsa chitetezo. Galasiyo ndi yopepuka, yopatsa chidwi komanso yowoneka bwino ikagwidwa ndi dzanja limodzi, kupewa kutopa chifukwa cholemera kwambiri kapena mawonekedwe otsika mtengo.
Kuchokera kumbali yothandiza, galasi ili ndiloyenera pazochitika zosiyanasiyana: kumwa tsiku ndi tsiku kunyumba, kugwiritsa ntchito makompyuta a maofesi, kutumikira alendo kumalo odyera, ndi kusakaniza mipiringidzo. Mawonekedwe ake owoneka bwino komanso ocheperako amaphatikizanso masitaelo osiyanasiyana amkati, osafunikira zida zowonjezera zowonjezera komanso kuphatikiza mosasunthika pamaseti omwe alipo.
