Thawj lub tshuab tua hluav taws tau patented los ntawm chemist Ambrose Godfrey nyob rau hauv 1723. Txij thaum ntawd los, ntau hom tshuaj tua hluav taws tau tsim, hloov kho thiab tsim.
Tab sis ib yam tseem zoo ib yam tsis hais lub sijhawm - plaub lub ntsiab lus yuav tsum muaj nyob rau ibhluav taws muaj.Cov ntsiab lus no suav nrog oxygen, cua sov, roj thiab tshuaj lom neeg cov tshuaj tiv thaiv.Thaum koj tshem tawm ib qho ntawm plaub lub ntsiab lus hauv "hluav taws daim duab peb sab, "qhov hluav taws kub tuaj yeem tua tau.
Txawm li cas los xij, txhawm rau txhawm rau tua hluav taws zoo, koj yuav tsum siv lubraug tua hluav taws.
Txhawm rau kom tua hluav taws zoo, koj yuav tsum siv lub tshuab tua hluav taws kom raug.(Duab / Greg Friese)
