Kukho iindlela ezimbini eziphambili zokuvelisa i-sodium sulfide. Indlela yetyuwa kaGlauber ibandakanya ukuxuba i-sodium sulfate kunye nomgubo wamalahle kwi-ratio ye-1:0.5 kwaye uzifudumeze kwisithando somlilo esijikelezayo ukuya kwi-950°C, kunye nokuxuba okuqhubekayo ukuthintela ukuxinana. Igesi ye-hydrogen sulfide ephuma kwimveliso kufuneka ifunxwe kusetyenziswa isisombululo se-alkaline, kwaye ukungaphumeleli ukuhlangabezana nemigangatho yonyango lwegesi yokukhupha umoya kunokubangela izigwebo ezivela kumagunya okusingqongileyo. Indlela yemveliso ephuma kwimveliso isebenzisa ulwelo olungcolileyo oluvela kwimveliso yetyuwa ye-barium, olufuna amanyathelo amahlanu okuhluza. Nangona oku kunciphisa iindleko ngama-30%, ubumsulwa bunokufikelela kwi-90% kuphela.

I-Sodium sulfide ikhetha izinto ezikrwada ezikumgangatho ophezulu kwaye ilawula ngokungqongqo imveliso ngokusebenzisa ubuchwepheshe obuphambili, ngobunyulu obuphezulu kunye nokungcola okuncinci, iqinisekisa ukubonelela okuzinzileyo nokuba kwiiodolo ezinkulu. Cofa apha ukuze ufumane i-sodium sulfide ekumgangatho ophezulu nesebenza kakuhle.
