(1) Ming’alu ndi vuto lofala kwambiri la mabotolo agalasi. Ming'aluyo ndi yabwino kwambiri, ndipo ina imangopezeka mu kuwala konyezimira. Mbali zomwe zimachitika nthawi zambiri ndi pakamwa pa botolo, botolo ndi phewa, ndipo thupi la botolo ndi pansi nthawi zambiri zimakhala ndi ming'alu.
(2) Kunenepa kosiyana Izi zikutanthauza kugawa kwagalasi kosagwirizana pa botolo lagalasi. Makamaka chifukwa cha kutentha kosiyana kwa madontho a galasi. Kutentha kwapamwamba kumakhala ndi kukhuthala kochepa, ndipo kuthamanga kwa mphepo sikukwanira, komwe kumakhala kosavuta kuwomba, zomwe zimapangitsa kuti pakhale kugawidwa kwazinthu zosagwirizana; gawo la kutentha lotsika limakhala ndi kukana kwakukulu ndipo ndilokulirapo. Kutentha kwa nkhungu sikufanana. Galasi yomwe ili kumbali ya kutentha imazizira pang'onopang'ono ndipo imakhala yosavuta kuwomba. Mbali yotsika yotentha imawomberedwa chifukwa galasilo limazizira msanga.
(3) Kusintha Kutentha kwa dontho ndi kutentha kwa ntchito ndizokwera kwambiri. Botolo lotulutsidwa mu nkhungu lopangidwa silinapangidwe bwino ndipo nthawi zambiri limagwa ndi kupunduka. Nthawi zina pansi pa botolo likadali lofewa ndipo lidzasindikizidwa ndi zizindikiro za lamba wotumizira, zomwe zimapangitsa kuti pansi pa botolo zisagwirizane.
(4) Kutentha kwadontho kosakwanira kumakhala kochepa kwambiri kapena nkhungu imakhala yozizira kwambiri, zomwe zimapangitsa kuti pakamwa, phewa ndi mbali zina ziwombedwe mosakwanira, zomwe zimapangitsa kuti pakhale mipata, mapewa omira ndi machitidwe osadziwika bwino.
(5) Madontho ozizira Madontho osafanana pagalasi amatchedwa madontho ozizira. Chifukwa chachikulu cha vutoli ndi chakuti kutentha kwa chitsanzo kumazizira kwambiri, zomwe nthawi zambiri zimachitika poyambitsa kupanga kapena kuyimitsa makina kuti apangidwenso.
(6) Zotuluka Kuwonongeka kwa mzere wa msoko wa botolo lagalasi lotuluka kapena m'mphepete mwa pakamwa potulukira kunja. Izi zimayambitsidwa ndi kupanga kolakwika kwa zigawo zachitsanzo kapena kuyika kosayenera. Ngati chitsanzocho chawonongeka, pamakhala dothi pamwamba pa msoko, pamwamba pake chimakwezedwa mochedwa kwambiri ndipo zinthu za galasi zimagwera mu nkhungu yoyamba isanalowe m'malo, gawo la galasi lidzatulutsidwa kapena kuphulika kuchokera pampata.
(7) Makwinya ali ndi mawonekedwe osiyanasiyana, ena ndi opindika, ndipo ena ndi makwinya abwino kwambiri pamapepala. Zifukwa zazikulu za makwinya ndikuti dontholo ndi lozizira kwambiri, dontholo ndi lalitali kwambiri, ndipo dontholo silimagwera pakati pa nkhungu yoyamba koma limamatira ku khoma la nkhungu.
(8) Zowonongeka zapamtunda Pamwamba pa botolo ndizovuta komanso zosagwirizana, makamaka chifukwa cha zovuta za nkhungu. Mafuta opaka mafuta mu nkhungu kapena burashi yonyansa amachepetsanso khalidwe la botolo.
(9) Mapiritsi Ma thovu omwe amapangidwa panthawi yopanga mapangidwe nthawi zambiri amakhala ma thovu akuluakulu angapo kapena tinthu tating'ono tating'ono tomwe timagwirizana, zomwe zimakhala zosiyana ndi tinthu tating'onoting'ono tomwe timagawirana mugalasi lokha.
(10) Zikhomo za scissor Zizindikiro zodziwikiratu zomwe zatsala pa botolo chifukwa chosameta bwino. Dontho lazinthu nthawi zambiri limakhala ndi zingwe ziwiri. Chizindikiro chapamwamba cha scissor chimasiyidwa pansi, chomwe chimakhudza maonekedwe. Chizindikiro chapansi cha scissor chimasiyidwa pakamwa pa botolo, chomwe nthawi zambiri chimakhala gwero la ming'alu.
(11) Infusibles: Zinthu zopanda magalasi zomwe zili mugalasi zimatchedwa infusibles.
1. Mwachitsanzo, silica yosasungunuka imasandulika kukhala silika yoyera ikadutsa powunikira.
2. Njerwa zosakanizika mumtanda kapena phula, monga fireclay ndi hight Al2O3 njerwa.
3. Zida zopangira zimakhala ndi zonyansa zosasunthika, monga FeCr2O4.
4. Zida zokanira mu ng'anjo ikasungunuka, monga kusenda ndi kukokoloka.
5. Devitrification wa galasi.
6. Kukokoloka ndi kugwa kwa njerwa zopangidwa ndi electroform ya AZS.
(12) Zingwe: Kusafanana kwa galasi.
1. Malo omwewo, koma ndi kusiyana kwakukulu kwapangidwe, kumayambitsa nthiti mu kapangidwe ka galasi.
2. Sikuti kutentha sikuli kofanana; galasiyo imasungunuka mofulumira komanso mosagwirizana ndi kutentha kwa ntchito, kusakaniza galasi lotentha ndi lozizira, lomwe limakhudza malo opangira.
