Default Wtf is this???

WTF is this?? I saw something on my Cu module.. burnt it with a 7W and 2W laser for like.. 30 minutes.. next morning I went to pick it up to move it and I saw this on the bottom.. o.O

Default Re: Wtf is this???

It was quite new when I had placed it at the base of my helping hands.. I had been noticing these "objects" quite often.. more and more at the time.. I felt as if the more I build and used lasers the more I saw.. I thought I was going nuts.. You can't see anything with the naked eye and normal lighting, however I passed the stimulated emissions over the bottom of my 12mm Cu Back Half and I saw something circular which appeared to take on the shape of the bottom of the module, which by the way was lying on it's side at the time. When the blue 455-465nm beam passes over these things you will see some of the coloring in it's spectrum break up and cause the object's shape to become irradiated in pink and purple - red and orange when the beam is tight enough and actually burns it.. which is what I did.

I had my 2W 2x26650 trained on it and this thing has always had a tight beam (high efl lens) and it's only a 5.6mm diode which already has a tight beam - however it wasn't enough to burn this sucker - it began to produce a bright spot, however it wasn't actually burning. That's when I pulled out the 2x18350 7W and I blasted that mother lover with both for about 30 minutes when I began to see the irradiated purple/pink/blue donut begin to disappear - it kind of looked like it was trying to sneak up the sides of the module and away out of sight, kind of going downward and to the background (if the module is on it's side and you're facing the bottom). I didn't notice at first because shortly after I had gone to bed, it was very late. When I woke up I found the above "whateverthefuuuu" it is. This was actually months ago and I had only recently taken these pictures and posted them - people are for sure going to think I'm a nut now.

When the residue, or possibly burnt ET skin - I didn't mention much out of fear of ridicule. However, the first time I noticed these "cloaked" objects.. it looked like a damn Chameleon - which I burnt as well, but with two high powered lasers, one 6W and one 7W. However, this one didn't burn AT ALL. At times it would turn into the beam and it would disappear from view, until I would point at it from a different angle, then the shape would become revelead again as it deflected the radiation around itself. After a while I just grabbed my show and smacked it - no body or anything to be found.. but a spot of some clear greasy substance on the cardboard box this took place on.

Yeah, now most of you are going to 100% believe I am making this up.. or that I'm a cook... haha.

I just can't stand it anymore, whatever is going on it's been getting worse. There are many specs of what appears to be crumbs and/or fungus at times all over my room, and these things smell awful when burnt - but they also do something weird which leads me to believe they're related to the chameleon and the blob - the cloaked objects. EDIT (Addition): Oh and I forgot to mention, when I burn these things, more show up and they appear to be growing into the carpet.. mimicing carpet.. God, this sounds nuts.

I actually thought I was going nuts. So I would call my roommates or friends to come in to check it out.. and while I would laze one of the "objects" I would ask them what they see and they would trip out.. they'd see at times.. the beam just stop mid-air and then continue a few inches later.. that would grab their attention. Then, when the beam would hit it at the right angle to reveal it's shape they would sort of clam up, look slightly bothered, and just ignore it and leave the room. One of them was my roommate, a cute latina who moved in after the room was vacant for but a SINGLE DAY and she moved in right away, and she works at, believe this or not, a LASER OPTICS company out here in Costa Mesa, CA. She said, "it looks like interference," and I told her, "I can burn it, do you want to see?" to which she replied, "I wouldn't," turning and leaving as she spoke.

Default Re: Wtf is this???

Hard to say what that is in the pictures - it actually looks somewhat like a fungus/mould. Could also be some sort of mineral deposit, perhaps the copper has reacted with something and formed a coating made of some copper compound. Scrape a little bit off and stuck it under a microscope... See if it is soluble in water, do a pH test if it is. If not - see if it's soluble in acetone/isopropyl alcohol. See if a small amount burns under a flame - if so - what colour does it burn?

Not sure about the chameleon cloaking stuff ... Although I will point out, it is possible for a beam to disappear midair and then reappear further on if there are no particulates in that patch of air for whatever reason... Although usually you'd need some sort of container to isolate that patch of air so that it doesn't mix with the surrounding environment.

I have more images which I will post eventually. I am trying to capture a nice clear image of what I am seeing that isn't easy to pick up on camera when a laser is being used. These things aren't stationary, they move.

The stuff on the module looks like the copper was exposed to a corrosive compound or the result of electrolysis. A flame test would be interesting. Get a sample on an iron wire loop and see if you get the usual copper green in the flame or something else.

Rust only refers to Iron Oxides - this doesn't look like any of the Iron Oxides I'm familiar with - nor does it look like Copper Oxide. As WizardG said, it looks more like it was exposed to something corrosive or used for electrolysis. I'm leaning towards it not even being a copper compound - common copper compounds are mostly all always blue/green/black/redishbrown - less so black/redishbrown in my experience.

Perhaps there was a coating/finish on the copper that reacted with something?

Again, flame test, solubility test, pH test depending on results of solubility test.

Edit: I kinda miss doing chemistry now ...

Yeah. That's why my first thought was mercury----amalgamated copper. The flame test color for mercury would be red if I remember correctly so copper amalgam should be sorta yellowish green, but not the bright yellow of sodium.

Yeah. That's why my first thought was mercury----amalgamated copper. The flame test color for mercury would be red if I remember correctly so copper amalgam should be sorta yellowish green, but not the bright yellow of sodium.
Yeah that could make sense, but people don't usually just leave chunks of mercury lying around all over the place... Not sure what the colours would be for a mercury flame test and couldn't really find any results on Google. I don't imagine people are going around burning mercury/mercury compounds all that often...

I actually enjoyed the first few years of history, but slacked off in the last year - teacher let us get away with it too. I think the essay writing was my problem.

What was the nickname?

So, I googled it and copper will not readily form an amalgam with mercury.

Another thought; besides the flame test you might try leaving a piece of clean copper on the carpet that's growing the weird yellow-orange ........fungoids(?) See if that develops the same type of corrosion(?) Just wondering whether the carpet weirdness is related to the module weirdness.

On the topic of the weird 'things' that you've seen and tried to burn with limited success; maybe you opened a portal playing with those high power lasers. I told you not to cross the beams!

Resident chemist here...

I doubt it would be mold or bacterial growth, as copper is fairly toxic to such microorganisms and they usually don't grow that fast anway.

The pictures are a bit difficult to interpret though.

It looks like copper has gone into solution and was deposited back onto it's original mass, but that would only happen if the copper was in a solution and some current was flowing through that as well. From the pictures i can't really tell if some material was eroded away or it's just deposition.

Either way it looks like somehow this can was electropated with probably copper from the photos, regardless if that copper orginally came from this part of the component or from something else.

This would only be possible if it was immerged in liquid though.
