Hello Dear forum members, here is another question for you.
Why gold precipitated with NaSO3 melts very quickly with any cheap Chinese torch lighter in minutes.
Gold precipitated with FeSO4 melts only after heating it up with a MAPP torch for like 5 minutes. It is almost impossible to melt gold precipitated
with FeSO4 with normal butane.
