S: Ma dhalaali karaa dahab la'aan?
J: Haa, waxaad dhalaali kartaa dahab la'aan. Dahab saafi ah, oo leh meel dhalaalaysa oo ku dhow 1064°C (1947°F), ayaa lagu dhalaali karaa iyadoo la isticmaalayo il kulaylka sare leh sida propane- tooshka oksijiinta ama foornada korontada. Flux waxay ka saartaa wasakhda waxayna yaraynaysaa oksaydhka, laakiin haddii dahabku saafi yahay oo oksaydhisku aanu arintu ahayn, qulqulka looma baahna. Si kastaba ha ahaatee, qulqulka ayaa kor u qaadi kara tayada dhalaalka marka la macaamilayo dahab aan nadiif ahayn.
