71 hours 14 minutes …
Silver growth more robust
Anode basket was 1/2 mark

[BGDOCK]

Day four (the stop watch function quit )
Solution same color
Conductivity .3 A/1. VDC
Crystals had to be knocked down today
Trr

Had to shut it last night
Slimes dropped on the crystals twice
Looks like the plastic coating on the wire started to deteriorate .
Cleaning up , cementing 1/2 the electrolyte out
Cement silver looks great
Probably the last time using the graphite anode

200 grams of 99.9? Silver from silver crystals harvested this weekend.

Lessons learned
Time for stainless steel bowl
new crucible (ordered )
Found lead and tin in one sample
99.43/ 97/94
Didn’t keep track of the ugly bars when melting into bigger bar drag
