A: Biasane, nalika leleh emas, sampeyan bisa nyana mundhut watara 0,1 - 1%. Mundhut iki, sing dikenal minangka "mundhut leleh," utamane amarga impurities kobong nalika proses leleh. Contone, yen ana jumlah cilik saka logam liyane alloyed karo emas utawa rereged lumahing, padha bakal dibusak nalika emas tekan titik leleh sawijining. Uga, jumlah emas cilik bisa ilang ing wangun penguapan ing suhu dhuwur, sanadyan peralatan leleh modern dirancang kanggo nyilikake iki. Nanging, jumlah kerugian sing tepat bisa beda-beda gumantung saka kemurnian emas awal, cara leleh sing digunakake, lan efisiensi peralatan kasebut. Kanthi leleh vakum, dianggep minangka mundhut nol.
