Accepted! Don't worry, I'm not mad. As you spend more time around the forum you'll see that I get along pretty good with folks.

I'm sorry to hear about your wife. My thoughts and prayers are with her.

Thank you. She is recovering and doing fine. But I can't begin to tell you how involved we are in the whole health care debate. It is a very emotional topic for us. Once again, I am sorry for not taking the necessary time to read your posts. This whole misunderstanding was my fault, I take responsibility for it, and am sorry for my over reaction. I appreciate your generosity and understanding.

Glad that was resolved.

Sfchemist, I'm sorry about your wife's predicament. I don't really understand it that well, but it seems to have passed, according to what I see on Yahoo News.

Thanks for all the input guys and sorry for the lack of replies - Been busy for about a week.

I have read, re-read and re-re-read most of it and its still not sinking in! Hopefully if I try again in the morning I'll have more luck.

Wish I'd spent more time in Chemistry class listening to the teacher rather than trying to chat up the girl with the great rack. I still blame her for my lack of Chemistry knowledge.

Brad,
You're welcome. This whole subject on bronze 'disease' has me interested. I have a few ancient coins laying around but most of them are silver denarii and I've never messed with ancient bronze coins. Although, for some inexplicable reason, I found a container of Renaissance Wax (Ren-Wax) in my cabinet but have no idea why or where it came from. If you would like to experiment with some let me know and I'll send you a little dab...sounds like an old Brylcreme TV commercial ;) I certainly wouldn't put this stuff on any expensive bronze coins without doing a lot of research on its long term effect. Although now that I think about it, I do sort of remember getting this stuff (Ren-Wax) for a potential project on ancient bronze coins but never pursued this particular numismatic avenue. I'm now collecting Morgan VAM Varieties and Bust Halves.

Thanks for the wax offer. I might take you up on it someday, but right now I'm buried in chemistry projects between my book and a new protective coin conditioner I'm working on.

What kind of chemisty did you do before you retired? It's cool to have another scientist around here.

I was an analytical chemist working for a private environment lab running a number of EPA analytical procedures. I operated a GC/MS, LC/MS (Thermospray from HP), various other GCs and LCs with a number of different detectors. Have extensive work studying and analyzing Aflatoxins on tree nuts. I was a nerd, still am I guess, wore a white coat, stood in front of analytical instruments all day and even wore a pocket protector. And yeah, I'm bald, and wear glasses.....gee, I really am a nerd. !

I can't offer any opinions or advice on bronze disease but just wanted to thank everyone for the discussion. This really is one of the most educational forums. And it's great to see that problems over differences of opinions can be resolved. Would that the world's politicians had the same capacity.

To sfchemist: I hope your wife makes a full recovery. By the way, on your "extensive work studying and analyzing Aflatoxins on tree nuts", just how did you get the tree-huggers to let you to conduct your experiments on them?

Actually it was not a problem at all. Aflatoxin is a
metabolic by product of a mold growth from the
species: Aspergillus flavus. This toxin is actually
found in the edible portion of tree nuts such as
almonds and pistachios, and also in peanuts.
It is highly carcinogenic and has even been found
in cow's milk originating from contaminated feed.
Not to be an alarmist, but I only purchase tree nuts
from major well known suppliers like Planters.
And no, I am neither a stockholder nor affiliated
with Planters ;)
Aflatoxin is a serious naturally occurring toxin that is very harmful at even low levels measured at the part per billion level.

COOL! I'm an analytical chemist too. I'm the head (senior) chemist for my companies analytical lab. We run a lot of instruments: SEM-EDXRF, X-Ray fluorescence spec, FTIR with DATR, HPLC DAD + ESA ELSD, CIA, KF Analyzer, UV spec, Auto VISC, Ion Chromatograph and an AA.

We manufacture metalworking fluids so we do a LOT of testing and studying metal-fluid interactions. Thanks why I'm able to bring a lot to the numismatic side of things....I study metals and fluids every day.

Brad,
Do you happen to know a fellow numismatist, Chris Pilliod? I met him years ago and he is a very intelligent and friendly guy who specializes in metallurgy and is well versed in US mint operations. Haven't heard from him in a while and if he happens to see this posting...Hi Chris!
Your mention of XRF brought back fond memories of my work using this technique to determine bromide levels (from Methyl Bromide fumigation) in a variety of stored food products. I've spent a great deal of time using HPLC reverse phase chromatography but have had little experience with diode array....most of my work used traditional UV/Vis and Fluorescence detectors. We did a lot of EPA 531.1 and 632 analyses using a Hewlett Packard HPLC/MS, which proved to be a powerful tool in the identification of these various pesticides. Oh, the memories, I haven't been in a lab in some time but it was always a lot of fun.
Thanks for writing,
Wayne
