Hi guys. I just finished inquarting my gold with copper (my first ever attempt at gold refining!). I cleaned and smelted the metal in a graphite crucible using a ceramic/Propane fueled furnace, and poured it into water. The metal has some flecks of black in it which doesn't wash off. Pictures attached.
Is this normal (or will it be removed during the refining process)?
Any help is appreciated
Thanks, - Mike.
