Galasi yowongoka-yonyamula pawiri-yopangidwa ndi galasi lapamwamba la borosilicate, lomwe limaonekera kwambiri, limakulolani kuona bwino mtundu wa madziwo, komanso limakhala lamphamvu moti silingathe kupirira kutentha kwambiri (silingathe kusweka ngakhale mutathira madzi otentha kuchokera mufiriji), ndipo sikophweka kusiya mikanda kapena kusweka kwa tsiku ndi tsiku. Poyerekeza ndi magalasi owonda-wamba okhala ndi mipanda, kulimba kwake kumakhala bwino.
Kapangidwe kake ka magalasi owongoka-awiri,{1}}otuluka pawiri{1}ndi magalasi apawiri mbali zonse za thupi. Mphuno yotakata imakhala ndi 8mm yotsegula ndi m'mphepete mwake, kuonetsetsa kuti madzi akuyenda mokhazikika pamene akutsanulira zakumwa monga mkaka ndi madzi oundana popanda kusefukira pa khoma la galasi. Spout yopapatiza ndi nsonga yakuthwa ya 2mm, yopangidwira zinthu zowoneka bwino monga uchi, manyuchi, ndi mafuta ophikira, zomwe zimalola kuti madziwo azituluka mozungulira ndikupewa vuto la zinthu zowoneka bwino zomwe zimamatira pagalasi.
Chogwirira chamatabwa cholimba cha magalasi-owongoka aŵiriwa ndi opangidwa ndi-grained natural hardwood. Imayeretsedwa katatu ndipo imayikidwa ndi chakudya- phula la phula, zomwe zimapangitsa kuti ikhale yosalala, yosalala-yopanda malo yomwe imamveka bwino m'manja komanso yosaterera ngati zogwirira zapulasitiki. Chogwiririracho chimapangidwa mwaluso kuti dzanja lanu likhalebe lotambasulidwa mwachilengedwe ngakhale galasi litadzaza ndi madzi, kuletsa kutopa kuti musamagwire bwino. Kutenthetsa kutentha kwa chogwirira chamatabwa kumalepheretsanso kuyaka pamene zakumwa zotentha zimatsanuliridwa mmenemo.
Zolemba za kapu zimasindikizidwa ndi inki yokhazikika ya UV, yokhala ndi chilembo chilichonse cha 1mm m'lifupi, kuchokera pa 15ml (0.5oz) mpaka 75ml (2.5oz), kuwonetsetsa kuti iwerengeka momveka bwino. Chizindikiro chaching'ono kwambiri cha 15ml chimakwaniritsa zofukiza zofukiza bwino, pomwe kuchuluka kwakukulu kwa 75ml ndikoyenera kumwa{8}}pang'ono pang'ono-khofi ndi tiyi. Cholakwika cholembera chimayang'aniridwa mosamalitsa mkati mwa ± 2ml, wofanana ndi kapu yoyezera akatswiri, ndikupangitsa kuti ikhale yoyenera kuyeza zakumwa (monga mafuta a chimanga ndi madzi a mandimu) pakuwotcha popanda kuwongolera kowonjezera.
Galasi yowongoka-yogwira,{1}}yokhala ndi mikwingwirima iwiri{1}amawonetsa tsatanetsatane wa kapangidwe kake. Maziko okhuthala amatsitsa pakati pa mphamvu yokoka akayikidwa pa tebulo, kuteteza kugogoda kosavuta. Kapu yonseyo ilibe mizere yokongoletsera yosafunika, ndipo khoma losalala lamkati limachotsa zovuta zilizonse-zofika-zofika pamakona, zomwe zimapangitsa kuti madontho otsala a khofi ndi tiyi azitsuka mosavuta ndi siponji kapena mu chotsukira mbale, kuteteza dothi ndi matope.
M'malo mwake, magalasi owongoka-ogwidwa pawiri-amatha kukhala ngati kapu yogawana{2}khofi, pomwe ma spout awiri amathira spresso ndi thovu la mkaka mosinthana; itha kugwiritsidwanso ntchito ngati kapu yoyezera ndi choperekera powotcha, kukulolani kutsanulira mwachindunji madzi omwe amayezedwa mu mbale yosakaniza; itha kugwiritsidwa ntchito ngati kapu yachilungamo ya tiyi, ndi ma spouts awiri omwe amatsimikizira kukhazikika kosasintha mu kapu iliyonse; ndipo itha kugwiritsidwanso ntchito ngati mtsuko wokometsera, ndi nsonga yopapatiza ikudontha mafuta a azitona pa saladi. Chikho chimodzi chimatha kuphimba zofunikira zoposa zisanu zakukhitchini, ndikuchotsa kufunikira kokonzekera ziwiya zingapo pazochitika zosiyanasiyana.
