More gold discovered, and you won't believe where!

Lately, I've been scrapping metal for a few extra $; Monday, I took a load of steel and lead and yesterday planned to take copper and aluminum. Before the Cu and Al trip, I had to deal with what I thought was a mixture of copper and aluminum in the radiator portions of an old air conditioner. I assumed that the coils were copper with aluminum fins, so my plan was to melt the aluminum off. Don't worry, the Freon was long gone. I built a fire in my mother's burning barrel and put the radiators on top; it didn't take long to see molten aluminum dripping and pooling underneath the barrel. It was very cool to watch, actually. The fire burned down, the aluminum started to harden and cool, and I began pulling aluminum "shapes" from the ashes. I got a pretty good pile set aside and, because the aluminum was still pretty warm, loaded the pieces into a wheelbarrow. Once things were cool enough to handle (with gloves), I put the aluminum in the back of my truck with the rest of the load. I got down to the point at which there were just little "crumbs" of aluminum and I noticed one of the crumbs was yellow. "Boy, that looks like gold!" I set it aside in a little container for safekeeping and later testing. As it turned out, the radiators were almost entirely aluminum, with only a few small pieces of copper that didn't melt. I took that load to the scrap yard and was happy with the $56+ it netted. As a precaution, I called my mother and told her not to do anything with the ashes from our fire until I had the little yellow crumb tested. Not one to let the grass grow under my feet, I went this morning to a local establishment that buys/sells gold and silver (among other things) and unloaded a few silver dimes and a war nickel. My real purpose, of course, was to find out what exactly my little yellow crumb was. "It's pure gold!" I got $11 and change for it (.2 pennyweight) and headed right over to Mom's. I started gently spreading ashes and sure enough there were more nuggets! There were also a lot of aluminum/gold alloyed pieces, which I might have to play with. It was an incredible sight, finding gold that you didn't even know existed 24 hours earlier. I can only surmise that the radiators had some gold in them somewhere; the only fuel in our fire was some sticks and the soundboard from a 100 year old piano (wood, glue and a few screws). I'll have to do more research, but the second batch of nuggets netted me $228.57; not a bad thing right before Christmas! The picture is the first crumb, posing with a Merc for sizing purposes. I didn't get a picture of the big batch because I didn't have my camera. What an amazing find!

I'm no expert but I can tell you from experience that the type of wood makes a major difference in the temperature of the fire. I build decks for a living, and we often build decks from an extremely dense tropical hardwood called ipe. The leftover short pieces of 1x6 ipe decking from a job make great firewood, and make for an unbelievably hot fire. I learned the hard way not to burn too many pieces at once, as I once melted the iron fireplace grate. We had to throw the grate out. Is it possible that the piano might have been made from a similarly dense wood?
Hard to say what the wood was; the piano was over 100 years old. I do have the manufacturers plate from inside the piano; maybe that information would help. Kleber Piano Co Pittsburg PA. Pittsburgh added the "H" back on to the end of its name around 1910.
 

Nice gold finds, halfdime!..and a very interesting discussion that has followed. It sometimes pays to be observant poke around in the dirt and ashes.

This was really just luck; if I hadn't found the original .2 pennyweight piece, I wouldn't have been looking for the rest. I'm not sure my mother would have noticed, though I probably would have scoured the ashes for more aluminum. Fortunately, we scoured for more gold! This is also why guys sift ash pits; you just never know!
 

Do u have a pic of it prior to filling it. I have several pieces I'm going to look hard at that I've found in some woods near a river where I've pulled many lead drops from casting I guess. One is a deeper red/orange then I think gold would be. Brass or copper I've always assumed it was. I have 7-10 lbs of lead droppings
 

Congratulations, halfdime, very cool and interesting. The melted gold seems to be somewhat of a mystery, especially the temperature of the fire. I am wondering about the varnish and/or other resins with which the piano was finished (as are many musical intruments) and what temperatures some of these oil based resins can generate. Just a thought, I have no personal knowledge, but a possible explaination.

Not sure what you mean.

There was a little glue, but this was the back of the piano so minimal varnish/resins (though some).
 

One reasons tropical hardwoods (like ipe) are so durable for outdoor use is that they are loaded with a black oily substance. When we burn ipe 1x6's you can watch the black oil bubble out the end of the burning boards--even on dry lumber. I do not have experience burning mahogany, but there a some similarities to ipe. I believe mahogany is sometimes used to make pianos.
 

Checking my "melting point of metals" chart, I see that copper melts at 1981. Last week, I got copper to melt as well, though not as completely as the gold. You're all welcome to be skeptical, but I've only done one "fabricated" post on TNet and that was on April Fool's Day several years ago. Otherwise, every one of my hundreds of posts and thousands of replies is absolutely true.

Sorry if my post came across as doubting you. I guess I was just thinking out loud when I said that the barrel of wood could not reach that temp.
Someone did make a good point that a lower karat gold will melt at lower temps. Maybe that is what happened. If you found gold in there, then I believe you and that is an awesome find!!

I think the best evidence now is that at least one gold coin was hidden in the piano wood (my next job is to figure out what it might have been based on how much gold I sold); American gold coins were 90%, which would be 21.4K. The gold I sold tested as pure, which doesn't rule out that it wasn't originally lower karat. Bottom line, we'll never know for sure what happened, which will cause me no end of sleepless nights! I still have a handful of aluminum/gold globs which I'd love to separate. If I could get them to a little higher than aluminum's melting point, theoretically I'd be able to extract whatever gold is left.
 

A little off topic but on one of these pages there was talk of melting the insulation off copper wiring. Around here the scrap yards will send you packing, they won't by scrap wire if you burn the insulation

Nice recovery on the gold though!
 

I will attest to the fact a wood fire will melt gold. I recovered several gold coins that went through a house fire and they looked like your piece multiple melted blobs. I was able to recover the majority of gold based on weight found and known coins lost. I was reluctant to do this search, but it was for a co, worker he lost his father that night. As to where your gold came from ?? HH

Congrats on your gold, half dime. :hello2: Quite an interesting story and mystery; it sure pays to be observant. :thumbsup:

And I believe a wood fire could reach high enough temps to melt gold, given the proper drafting.

I finally realized that I could come up with a good guess as to what (denomination) the source of this gold was. I was paid for 4.3 pennyweight, which translates into a little more than 6 grams. A $5 gold piece was in the 8.35 gram range, and I still have gold and aluminum mixed. My guess is that the culprit was a $5 gold piece, but we'll never know for sure. I still can't believe it.
