Geoff Wooff Posted August 1, 2020 Share Posted August 1, 2020 Some years ago I came across 60 grams of powered gold in a carton full cobbler's tools and materials. Have never yet found a use for it but I assume the cobbler was embossing boots and other leather goods or making 'gold size' perhaps. Anyone interested in making an offer ?

alex_holden Posted August 1, 2020 Share Posted August 1, 2020 If it's real gold, 60g is worth a small fortune. Link to comment Share on other sites More sharing options...
Geoff Wooff Posted August 1, 2020 Author Share Posted August 1, 2020 (edited) Alex, a small fortune ? Maybe the value of a nice concertina? I took it to one of those ' We Buy Gold' shops and they said yes it was gold alright, probably 24 k but in powder form it was not possible to re use it by melting. I guess there must be a chemical way of re-claiming it like they do with silver that has been dissolved during film processing.

I don’t know how they do it but there are companies that specialise in recovering scrap, e.g. filings from the jewellery trade. I just Googled and found this company in London: http://www.landalemetals.co.uk Link to comment Share on other sites More sharing options...

Perhaps I might get an Amboyna or Tortoise Shell Aeola out of the proceeds if I can find anyone to buy the powder. Link to comment Share on other sites More sharing options...
Sprunghub Posted August 3, 2020 Share Posted August 3, 2020 I think this chap implies he gets 2.5gms of gold 'nugget' from 1Lb of gold 'dust' after smelting.......? I am hopeless at maths ( math ) so no idea of the implications for 60gms of dust..... Link to comment Share on other sites More sharing options...

I don't know what his "gold powder" is; it looks more like dried mud than the high purity stuff you use for gilding. Link to comment Share on other sites More sharing options...
Sprunghub Posted August 3, 2020 Share Posted August 3, 2020 By the power of the mighty Google !!? More Googling may suggest how they get it to "stay" bright gold ( to the eye ).....it makes little sense that a base metal 'powder' can not be reconstituted, but I don't know if they add something to it as an anti-oxidant for that perpetual brightness. "The light brown powder is gold, if you crushed it with a glass stir rod it would look like gold, (or smeared in under pressure onto a piece of paper it would leave a gold streak), the pure powder will do this where impure gold will not do this or as well. To get the brown powder look like gold it is melted, it has something to do with particle size and reflection of light as to why this fairly pure brown power does not look like gold."

Hopefully the chap in the "we buy gold" shop was correct in his assessment that what Geoff has is high purity 24 carat gold powder like the stuff Stephen linked to, not a base metal bronzing powder. I just read the description on the video above - he says this powder is from 1lb of "trimmed gold fingers". I think he means that he cut the gold-plated copper contacts off the edge connectors on printed circuit boards and ground them up. Link to comment Share on other sites More sharing options...
LateToTheGame Posted August 4, 2020 Share Posted August 4, 2020 I'm glad you are getting some second and third opinions. The opinion of the We Buy Gold place seemed ill informed to me. A lllllooooonnnnggg time ago my grandfather-in-law was a prospector in Oregon and Mexico. These were in the days when the gold prices were strictly controlled at about $400. But he had bought and sold enough raw dust and chunks the size of grains of sand to make a poor living. This was the old guy with a shovel style prospecting so it was pretty labor intensive. He had a glass pill bottle in his pocket filled with stuff which looked as much like glittery grit than anything else. He told us was worth $500. Given his experience I had no reason to doubt him. Minimum wage was $1.50 at the time. Given how long he took to find the stuff I'm not sure how he fared compared to that hourly. Link to comment Share on other sites More sharing options...

I can see there is a lot of difference between gold dust or gold ore as one hopes to find when prospecting and powdered gold, which is what I found. This powder is so fine that touch a finger to it and smear it very finely on your skin , like make up,. It is as smooth as silk . Link to comment Share on other sites More sharing options...
Milesy Posted August 4, 2020 Share Posted August 4, 2020 Intrigued by the posts, I did a bit of searching and found this: https://www.horikin.co.jp/english/powder/85#:~:text=Metal Powder-,Gold powder and other types of powder,called « Kindei » Gold Powder. Could this be what you have? Link to comment Share on other sites More sharing options...
DDF Posted August 4, 2020 Share Posted August 4, 2020 That reminded me of something that has been on a shelf in the workshop for years.I just dug it out and took a picture I bought it thinking it was gold but when you put a metal detector/stud detector over it it doesn't register.I just put some in a drop of nitric acid and nothing happened so I guess its mica or goodness knows what.I think it was the box it came in mislead me originally.

There are a number of pigment powders that mimic gold. I have a couple of peanut butter jars full of some. I have a few boxes of powdered pigments from days when I had artistic aspirations. I do also have some gold leaf that is light as a feather it is so thin. I have no idea if it is actually gold or just gold like. Though a stud detector would not likely register. Or at least not the type I am thinking of that involves a magnet. Gold like aluminium does respond to a magnet.. Link to comment Share on other sites More sharing options...
DDF Posted August 5, 2020 Share Posted August 5, 2020 I think the detector works by induction, it does sense aluminium powder and gold metal. Link to comment Share on other sites More sharing options...
