AMAX copper medallic ingot (unusual)

dcarr

This type of thing is interesting to me and when I saw it offered for a fairly cheap price, I bought it for my collection of vintage non-precious ingots. Anybody who pours molten silver or copper knows that when it is very pure it will grow crystals as it cools into an ingot. This one really shows the crystals and I think that was the point of this promotional piece. As the light angle changes, different crystals "light up". This is probably the purest item of copper that I know of.

I have also noticed that the market for vintage collectible copper ingots is quite strong recently, especially for those that are souvenirs from mining companies and refiners.

Nice hockey puck!

That is cool looking, I wonder if they can control it enough to make the crystals all have a similar pattern/appearance or if each comes out unique?

Interesting ... that one is different. It has "AMERICAN METAL CLIMAX, INC." below the "AMAX" logo.

Every one should have a different crystal formation and pattern.
