It would certainly save me a lot of typing! LOLOL

I did most of the work on the book while I was laid-off. Just too much going on in my life to work on it. When I do have free time, I like to watch TV or play video games. It will happen eventually though.

 

All those pages ^ of much ado about nothing. Just swallow it today and rinse it tomorrow

 

I like it.......

It is the yearly HALLOWEEN avatar season !!!! Everybody is disguised as Doug !

 

I am a chemist also, but an organic chemist with an interest in inorganic chemistry and coins. I found some disagreement with the presentation and am not sure if I am just being picky or suspicious because of other inaccuracies. On slide 4 we are told that some bronze disease is caused by the production of acid internally!!? What does that mean? Slide 9 assures us a patina is oxidation, but he doesn't mention that many acids are "oxidizing" acids, so can acids cause patina to form. He also mentions a 5% molal solution, which is like saying 5 cents dollars. Finally he tells us on slide 19 that ethanol is a dangerous chemical and difficult to purchase...maybe if you are under 21, those over 21 can purchase 40 or 50% solutions as Vodka (whatever brand you like) or as 95% Everclear Pure Grain Alcohol.

Patina, corrosion, verdigris are mostly the same animal since it is not a well defined animal, and a lot depends on surface factors, crystal growth and density of deposition, which is way beyond my scope, but at least I know it is. All this being said, I appreciate a good patina but decry verdigris.

 

OK, now I totally understand it : - )

 

I have realized by reading this whole discussion that coin collecting is no longer a hobby but a job.

 

I never thought of it that way, but if you eat a lot of olive oil it makes the cleaning process less stressful

 

I think that would have been a better statement in this thread:

Now buying antique digital wristwatches. Hopefully copper ones with a lot of vertigris and green patina so I can tell where the watch goes on my wrist.

 

Gonna be difficult to swallow a wrist watch, regardless how much olive oil you chase it with, and even worse tomorrow ...

Unfortunately, I do not see any copper.

 

As an old geek in the circus once told me "If you swaller a snake, chase it down with some olive oil. They go down easy but come out rough."
