Another metal find to identify

[Wally69]

Went out for another 10 minute swing in the park next door and found another metal nugget/blob.

A quick bath in Albright shows it as silver, but what type? Any ideas how to identify?

It doesn't look like a fire/slag blob as the shape is unusual and has a feather-like surface texture, any ideas on how it was formed?

looks as though it is torn maybe by a mower blade?

Originally thought that, but ripples are smooth and rounded and there are some on the smooth side as well.

Probably a bit of molten aluminium, from a can or something, you quite often find blobs on the beach from people throwing them into fires. I reckon the rippled side was exposed to the air when cooling resulting in the texturing, whilst the smooth side was a lot hotter, sitting face down in the fire, where the cooling was a lot slower. Just an out there guess!

Could be Goldpick; thought aluminium may have shown some oxidisation. It is my first bottle of Albright, so not sure of the expected results of aluminium v's silver.

Anyone know of a backyard test? I have a blow torch - does one produce a different coloured flame to the other?

How heavy is it Wally, specific gravity test should help, unless it's an alloy of some type. The SG test Col posted up works great.

some people melt bronze and throw it around in the attempt to imitate gold nuggets could be bronze

 

[Wally69]

Thanks guys - sg has it slightly heavier the aluminium range but definitely not as heavy as silver.

Other one is bronze

Melted coins perhaps?

could be as the Duck says, we have used ali-bronze slag or I think it is correctly called aluminium bronze which some blokes at a bronze foundry gave us to imitate gold at a living history event (1850's period). It usually stays bright and it's cheap so we could afford to salt a creek bank and then let the guys go for it with their cradles. All just for fun of course.
