Gold Bar, or scrap junk..

Bleach test is not scientific. Do me a favor so I can help you.

Get a pan, aluminum foil, and baking soda.

1. Fill the pan with water and but on stove.
2. Crinkle aluminum foil, uncrinkle and then place on bottom of pan.
3. Add two scoops of baking soda.
4. Add heat, hold below a boil.

If any part is a noble metal then you will see bubbles come off of the object itself and leave behind a black soot. Take pictures. The baking soda will bubble when heated, this is not the same. The bubbles must form and come off the metal. If they do...let it sit and there for 15minutes. Then take out and rinse with soap and water. Plan back in until clean. Add more water and baking soda as needed. Replace aluminum as it gets cannibalized.

Any other "home test" is just spitting in the wind.

i took it out, the one side is completely clean, no rust on it. i broke the thing in to so i could see a comparison between the test, the one side that bubbled is clean.. so what metal does that make it?

Even if it is 40% silver it is worth its weight in iron unless you have 100's of pounds of it.

The differences between junk metals and gold, silver, copper, brass and aluminum is easily noticeable and learned. Almost all gold jewelry comes out of ground like it went in as with the noble metal of platinum.

Silver may come out of the ground like it went in too but it will normally start to turn black in minutes. You can't mistake aluminum with silver because silver doesn't have the weight compared to the same mass of silver and it is noticeably softer, copper turns green from verdigris crystals, and brass turns a dark black-green. This all happends becaues oxidation, iron = rust red, copper = green/blue, brass = black/green.

Take new pictures...let me see the aluminum foil?
Did it leave a hole in the Aluminum foil, were black spects left behind?
How did you break it in half?

At this point in time I am guessing silver alloy of some sort. We have ruled out lead completely. Pretty safe to assume we have ruled out gold as well. I doubt the oxidation (black stuff) would come off the gold that quickly. It usually takes quite a few passes to clean up oxidized 14kt and less gold.

New pics please!

Also, give me weight and measurements in cm: width, length, and height.

Copper is still a possibility. Take a small file to it. If it gets gold colored and super shiny then you probably have copper. Pictures, pictures, pictures...

We have also ruled out aluminum.

I believe what you have is naturally occurring antimony...Sb https://en.wikipedia.org/wiki/Antimony

both densities calculate out around 6.9, density of antimony is 6.68. Antimony oxidizes so it will reduce in the pan. The color also matches. Antimony and tin/lead alloys are also possible.
