If you are old enough you would have seen numerous abandoned hulks just rusting away awaiting the day iron prices rose high enough to make their recovery economically feasible.
Yes, you would have seen them rusting away EVERYWHERE but the door hinges, or any other part of the body, that had been welded with an acetylene torch.
None checked out why that had happened until a young lady in the DC area won science fair after science fair demonstrating a technique for creating DIAMOND FILM with nothing more than a poorly tuned acetylene torch.
That method has since been put to work welding small diamonds together into large diamonds!
So, yes, quite ordinary processes which are quite commonly observed by great scientists and trash haulers alike can be totally ignored!
Now, how is it paint is actually mixed ~ been doing that one for thousands of years ~ what new wonders will be discovered as that process is subjected to intense scrutiny.
A common process that changes one isotope of mercury into several others is definitely something to look at!
Interesting info.
Thanks.
