11.5 ounces of fuzz button connectors

Ooooh ! Me wants a Precious like that !

Beatutiful result Topher.

Thank you aga. I will be showing off more beautiful buttons as I get the next toll refine done.

I look forward to you showing off your first button, as I'm sure it will be spectacular. :G 8)

It'll probably be more like a 'speck' than a 'tacular' !

One of the great things about this forum is how easy it is to see who is an Actual refiner, and who is just here to pose pointless questions that will never be put to any real use.

Anyone refining, especially for the first time, is naturally eager to show off their work/results.

The really experienced refiners don't so much, probably because they've seen much bigger and better
However, their answers to specific questions shows how much they have worked in refining, as they suggest Practical working solutions to problems, not just googled stuff.

This really is a great strength of this forum, and it helps keep it at such a High Quality.

The types of parasites that infest other forums can't live here for long - the Mods & Members 'refine' them out and discard them !

we obviously ain't trying hard enough in your case Aga.

Very true statement Aga!!!

Kids love sorting and counting--use that cheap labor! :wink:

I have pictures of my daughter, at about age 5, helping me when I was hand-cutting silver chainmaille rings. As they fell off the saw blade, she would pick them up with some long tweezers and put them in her nesting cups. She's now 11, and won't let me kiss her in public lol.

May sound goofy, but I've been thinking about getting back in to chainmaille jewelry...have any pics of your work?

I won't mess up the thread with pics, but at least one of my old JPL pieces is at my Etsy storefront (which I don't really maintain anymore).

The blue, likewise, is called molybdenum blue.

I did some aqua regia on 486 CPU:s recently and I ran into a deep blue almost waxy deposit on my beaker when I switched acids. It was hard to catch it on a picture, but here is my best shot.

Is this the "molybdenum blue" you mention? Googling it I found some articles about poly metallic compounds with heavy rings of molybdenum in various oxidation states. Specifically it mentioned Mo(VI) partly reduced into Mo(V) and a lot of oxygen. The molecules consisted of around 800 atoms creating Mo154-clusters and was made using nitrosyl (a chemical that exists in aqua regia). Is this what I accidentally created or does it have a more mundane explanation?
The reduction of molybdenum could have been from exposed metals when the AR level was dropping, most of the gold had already cemented back on remaining base metal.

I don't remember if I dissolved it in HCl or aqua regia, but it's gone now. I'm just curious of what I happened to see.

Göran, I don't know if this will help you, but
-
"Reduction of molybdate in acidic solution leads to formation of so-called molybdenum blues. The precise nature of these blue compounds is not known, but it generally is accepted that it is some mixed oxidation state compound (molybdenum in +6 oxidation state and +5 oxidation state in a single complicated ion or molecule). The blue material can be in solution, but it can also be colloidal."

An excerpt from this website-

Which, coincidentally (not really), was a website that Lou posted on another thread, although I believe it was the experiments on Ru oxidation states.

Thanks Topher, I had forgotten about that site and it didn't appear among the first hits when I googled "molybden blue". It is a wonderful site and I spent some time just browsing through the pages when Lou first posted that link.

I should have posted the wikipedia link I found, I thought I did but apparently I didn't...
https://en.wikipedia.org/wiki/Molybdenum_blue

This is also an interesting site, showing how molybdenum can form huge clusters.

Tungsten also does it.
