Well, it's that time of year again, time to renew the web hosting. And for those of you that don't know, that has become a lot more expensive than it used to be. Fifty dollars a year is now several hundred. Not to mention the price of domain names has gone up ten-fold.
And I just found out that the nice folks at PayPal disabled all my Support buttons, and I never got a notice (although that may be my fault.) In any case, it is all working again now, so if you would like to make a small donation to help defray these costs, it would be greatly appreciated.
These metals are of little interest as artifacts. They are, however, interesting for other reasons. Tin and zinc are used in copper-based alloys such as bronze, and the diver's favorite - brass. Aluminum, lead, and titanium are all used in the manufacture of many items of dive gear, not the least of which is tanks. And zinc is used in pure form in sacrificial anodes which protect the other metal parts of your dive boat from corrosion, while chromium and nickel are major constituents of many marine alloys. Wouldn't we all like to find a trove of silver and gold!
