Joseph Priestley ya fara hanyar carbonation a karni na 18.

Yawancin abubuwan sha na barasa, irin su giya, shampagne, cider, da spritzer, sun kasance a zahiri carbonated ta hanyar fermentation na ƙarni. A cikin 1662 Christopher Merret ya kirkiro 'ruwan inabi mai ban sha'awa'. William Brownrigg shi ne na farko da ya fara samar da ruwa mai carbonated, a farkon shekarun 1740, ta hanyar amfani da carbon dioxide da aka dauka daga ma'adanan. A shekara ta 1750 dan kasar Faransa Gabriel François Venel shi ma ya samar da ruwa na carbonated na wucin gadi, kodayake bai fahimci yanayin iskar gas din da ya haifar da carbonation ba. A cikin 1764, masanin kimiyar Irish Dokta Macbride ya ba da ruwa tare da carbon dioxide a matsayin wani ɓangare na jerin gwaje-gwaje akan fermentation da ɓarna.

A shekara ta 1767 Priestley ya gano hanyar cusa ruwa da carbon dioxide ta hanyar zubar da ruwa baya da baya sama da bututun giya a wani gidan giya a Leeds, Ingila.
