Galasi adabadwa koyamba ku Egypt, adawonekera ndikugwiritsidwa ntchito, ndipo ali ndi mbiri yazaka zopitilira 4,000.Magalasi ogulitsa adayamba kuwonekera m'zaka za zana la 12 AD.Kuyambira pamenepo, ndi chitukuko cha mafakitale, galasi pang'onopang'ono wakhala zinthu zofunika kwambiri pa moyo watsiku ndi tsiku, ndipo ntchito galasi m'nyumba akuchulukirachulukira.zosiyanasiyana.M’zaka za m’ma 1800, pofuna kukwaniritsa zosoŵa za kupanga makina oonera zakuthambo, magalasi oonera zinthu anapangidwa.Mu 1874, galasi lathyathyathya linapangidwa koyamba ku Belgium.Mu 1906, dziko la United States linapanga makina opangira magalasi athyathyathya.Kuyambira pamenepo, ndi kukula kwa mafakitale ndi kukula kwa magalasi, magalasi okhala ndi ntchito zosiyanasiyana ndi machitidwe atuluka.Masiku ano, galasi lakhala chinthu chofunika kwambiri pa moyo wa tsiku ndi tsiku, kupanga ndi sayansi ndi zamakono.
Zaka zoposa 3,000 zapitazo, sitima yamalonda ya ku Ulaya ya ku Foinike inadzaza ndi mchere wonyezimira wotchedwa “soda wachilengedwe” ndipo inayenda pamtsinje wa Beluth m’mphepete mwa nyanja ya Mediterranean.Chifukwa cha kuchepa kwa mafunde a m’nyanja, ngalawa ya amalondayo inamira, choncho ogwira ntchitoyo anakwera m’mphepete mwa nyanjayo mmodzimmodzi.Ogwira ntchito ena adabweretsanso mphika waukulu ndi nkhuni, ndipo adagwiritsa ntchito zidutswa zingapo za "soda wachilengedwe" monga chothandizira kuti mphika waukulu uphikire pamphepete mwa nyanja.
Ogwira ntchitowo atamaliza kudya, mafunde anayamba kukwera.Atatsala pang’ono kunyamula katundu ndi kukwera m’ngalawamo kuti apitirize kuyenda, munthu wina mwadzidzidzi anafuula kuti: “Anthu onse, bwerani mudzaone, pamchenga pansi pa mphikawo pali zinthu zowala ndi zonyezimira!
Anthu oyendetsa sitimayo anatenga zinthu zonyezimirazi n’kupita nazo m’ngalawamo n’kuziphunzira mosamala.Iwo anapeza kuti mchenga wina wa quartz ndi soda wachilengedwe wosungunuka unamamatira ku zinthu zonyezimirazi.Zikuoneka kuti zinthu zonyezimirazi ndi soda wamba amene ankapangira miphika pophika.Pansi pa moto wamoto, adachitapo kanthu ndi mchenga wa quartz pamphepete mwa nyanja.Ili ndiye galasi loyambirira.Pambuyo pake, Afoinike anaphatikiza mchenga wa quartz ndi soda zachilengedwe, kenaka anazisungunula mu ng’anjo yapadera kuti apange mipira yagalasi, zomwe zinapangitsa Afoinike kupeza ndalama zambiri.
Cha m’zaka za m’ma 400, Aroma akale anayamba kugwiritsa ntchito magalasi pazitseko ndi mazenera.Pofika m'chaka cha 1291, teknoloji yopanga magalasi ku Italy inali itapangidwa kwambiri.
Mwanjira imeneyi, amisiri a magalasi a ku Italy anatumizidwa ku chilumba chakutali kukapanga magalasi, ndipo sanaloledwe kuchoka pachilumbachi m’moyo wawo.
Mu 1688, mwamuna wina dzina lake Nuff anatulukira njira yopangira magalasi akuluakulu, ndipo kuyambira pamenepo, galasi lakhala chinthu wamba.
Kwa zaka mazana ambiri, anthu akhala akukhulupirira kuti galasi ndi lobiriwira ndipo silingasinthidwe.Pambuyo pake anapeza kuti mtundu wobiriwira umachokera ku chitsulo chochepa muzitsulo, ndipo chitsulo chachitsulo chimapangitsa galasi kuwoneka lobiriwira.Pambuyo powonjezera manganese dioxide, chitsulo choyambirira cha divalent chimasandulika kukhala chitsulo chokhazikika ndikusanduka chikasu, pomwe manganese a tetravalent amasanduka trivalent manganese ndikusanduka chibakuwa.Optically, chikasu ndi wofiirira akhoza kugwirizana wina ndi mzake kumlingo wakutiwakuti.Akasakanizidwa pamodzi kuti apange kuwala koyera, galasilo silidzakhala ndi mtundu wamtundu.Komabe, patapita zaka zingapo, trivalent manganese adzapitiriza kukhala ndi okosijeni ndi mpweya, ndipo mtundu wachikasu udzawonjezeka pang'onopang'ono, kotero galasi lazenera la nyumba zakalezo lidzakhala lachikasu pang'ono.
