Lub ntsiab raw khoom rau zus tau tej cov sodium sulfate yog sodium sulfate, uas ib txwm tshwm sim nyob rau hauv daim ntawv ntawm glauberite thiab glauberite ore. Muaj ntau tshaj kaum hom glauberite ores nyob rau hauv cov xwm, ntawm uas ob yog cov muaj nqis peev xwm. Ib hom yog sodium glauberite (uas yog, glauberite decahydrate thiab anhydrous glauberite), uas feem ntau yog muab faib rau hauv cov dej ntsev niaj hnub, thaum calcium glauberite feem ntau muaj nyob rau hauv lub pas dej ntsev thaum ub. Cov khoom siv ntxhia ntawm mirabilite yog cov khoom siv tseem ceeb rau kev tsim cov sodium sulfate. Tam sim no, tag nrho cov pov thawj pov thawj ntawm mirabilite nyob rau hauv Suav teb yog nyob ib ncig ntawm 20 billion tons (xws li sodium sulfate anhydrous), qeb duas hauv ntiaj teb.
