Cool Beans Dok.....This ole gal has been riding for more than 40 years. Still, puts around on the Harley, but I want that rocket engine, The ultimate "Sleeper". Traci
In the microwave - isn't there the possibility that the peroxide could super heat and not boil at all which could cause an explosion with a sudden change in surface tension.
chances of reaching a "super heat" temperature in a microwave are nearly impossible. besides supercritical temperatures are a lot more fun
Might I suggest Verdigone. Better control, less chance of damaging the patina when removing the verdigris. Granted it isn't like exploding microwaves, but a heck of a lot safer. Jim
Never used them for coins, but from what I have read here on CT, not very well thought of. If you want my stab in the dark, using the proper chemicals (mild soap, acetone, xylene, etc.) set up so the coin is not rubbing on something (bottom?) to scratch it, I find it hard to believe that it would harm any coin.
Never used them myself, but I have seen reports that even using just water the coin can come out pitted. Now it may be time, it may be water content - I don't know. But based what I have seen said by those who have used them - I wouldn't.
Reports of just such things have occurred with tap water being removed from microwaves. Explosions have occurred when surface tension was disrupted: "It was not boiling but when I tried to move it out of the oven, then it just exploded!" But that requires a reference that escapes me right now.
Mythbusters pretty much debunked that. They thought that if you started with absolutely pure water, it might be possible with a lot of luck. As for the H2O2, since the peroxide starts to decompose at 176° F, I would be nearly positive that would break up the super heating.
I too think even discussing such things on this forum is dangerous. There are way to many out there that try things with little to no idea what is real and what isn't. This is why on those Wrestling programs they constantly emphsize not to try those things they do yourself. To many times people see or read something and try them with horrible results. Even playing around with chemicals like Acetone and Xylene without knowing the total effects of the actual chemical's properties and possible dangers of the fumes is completely irrisponsible. For such precautions and warnings always first go to government controled web sites like ATSDR. This is the Agency for Toxic Substances & Disease Registry. Although you may think your safe from an explosion of flame flash back, the fumes given off may end your life, eye site, internal organs, etc.
I've got an older brother, OCD'ed to the Max. He has a Sonic cleaner which he has used to clean camera parts for years. (He even knows how to put Rollei's/Leicas/Nikons back together, way ahead of me. Ok. He's really good at it & ran a camera repair business.) Says NH3 in mild solution with UC worked in Viet Nam. But that was to return machines to service. I didn't asked about how pretty they were. Perhaps I'll get a lb or two of wheaties and do a thread on the results. Any questions?:stooge:
Well, maybe it was just a case of water from reverse osmosis, placed in a non pressurized jet at 65,000 ft and placed before the radar the thaw it out when they hit some wind sheer. So many facts, so little time.:bigeyes:
You do not want ammonia. Period. Next, you do not want a pound of wheaties. How are you going to keep them from rubbing each other? Then, you are going to have to make a bracket to hold the coins so they rub NOTHING - another coin, the cleaner, even the holder. Any rubbing will ruin the coin. Good luck!
Thank you for your concern. I was not looking to put the whole lb of wheaties in at once. I was contemplating titrated gradients of concentrations. Now to ammonia. You know a great deal about such stuff. I just have lbs of old sticky wheaties, searched, except for the one stuck together, and was hoping to decimate them in a meaningful way. Why not ammonia? (These are the coin that have already laughted off water intervention)
If you are trying to do something to recover the coin; If you are just trying to get them apart, try vinegar. It will eat them up quick and get them apart. They will also be bright and worthless.
why the heck are you microwaving hydrogen peroxide? is there a purpose or is this just another episode of jackass?
I had heard this worked as well and tried the peroxide/microwave experiment. No matter how long the coins (zincolns and lincolns) were in for, they never got any better than warm water could do and many zincolns corroded away under the copper.
I haven't read the other posts, but it doesn't seem like a great idea. H2O2 spontaneously decomposes to water and oxygen, and it's faster with UV in light (hence the opaque bottles). It would surely be faster in a microwave.
Copper is involved....oye vay..you don't nuke metal. I would imagine the folks that do nuke HP don't sit and watch it boil continuously, rather they heat it in a safe container and remove it as soon as it starts to boil, then place the subject into it after removing. I guess it's an innocent enough question or perhaps an attempt to broadly lump the "non conformists" together..who knows, but regardless..the "Oh my! That's really dangerous, you should never, ever...blah blah blah" generic lines are absolutely ridiculous when it comes to the heating of diluted HP in a microwave, but hey, you should also watch out for bird droppings falling from the sky too....after all they might cause an infection which might blind you or might potentially kill you as a result. Unbelievable..by the way...don't drive...don't walk, breathe speak or move either...they're are potential hazards..along with eating utensils, the shower, fueling your vehicle, shaking hands and picking your nose. Sheesh...good thing Ben Franklin didn't visit this place before he flew his kite. We might all be starting fires for the ambient light to see (which could be dangerous).
