Well, this week we had another bumper crap scrap trash to treasure episode. At this rate, I will never run out of free stuff to melt. Nearly 213kg melted already this year. Sit back and watch and get excited over crap scrap to treasure melt ingot casting lead, brass and aluminium.
Hoard weight 211785g 211kg
Aluminium 132626g (132kg)
Copper 38925g (38kg)

As I gaze at the coin I just discovered, the word "Eureka" comes to my mind. It is a 1973 two-pence coin that has been buried for years, and as a result, oxidization has occurred on its surface. This moment of realization happens as I realize that copper oxide dissolves in hydrochloric acid (HCL), leading to a cascade effect that eventually releases the gold foils that are present in the solution. As a result, copper chloride is formed and it cements out on the iron in the stock pot.
Rolled gold watch experiment
All the gold plating has been removed and the rolled sections are free from the copper. the main body of the watch is silver with a gold plate. Because it was in the ground for 100 years these two oxidized. Amazing.
1970s Gold pins experiment
Foils have released leaving silver pins and gold foils floating in a saturated solution.
Modern gold pins experiment
Copper pins exposed foils floating around in the solution.
Board slot connectors experiment
Both types released the foils exposing the copper base metals.
Very modern gold pins experiment
Failed due to not having enough time to oxidize. It takes between 5 to 30 years conditions dependent.
