... the amulet was made via a process called lost-wax casting — one of the most important innovations in the history of metallurgy. The age-old process, which is still used to make delicate metal instruments today, involves crafting a model out of wax, covering it in clay, and baking the whole thing until the wax melts out and the clay forms a hard mold. Then molten metal is then poured into this cavity and cooled until it hardens. When the mold is broken open, a perfect metal model of the original wax structure remains...

The Washington Post article claims this amulet was made by a process "still used by NASA." What a load! I've done lost wax casting. It is no big complicated scientific technology. In fact, as the article shows, it has been used for thousands of years.
A detectorist should know what lost wax casting is. Real reales were not cast in a mold.
You can melt broken silver or gold junk finds and make new objects using the process. You can take classes on how to do it.
Here is a youtube tutorial on the process.

The main definition of "amulet" is something like a small object worn to ward off evil, harm, or illness or to bring good fortune; protecting charm.
I don't know how they determined the purpose of the object was anything more than aesthetic. At times it seems that archaeology is accompanied by tons of wild imagination.

Darrel S. reports that Seagrape Trail was closed again. He reported a variety of pieces of metal at Turtle Trail and similar miscellaneous metal finds in recent days at Seagrape Trail.
Here is an example of what Darrel dug yesterday at Turtle Trail where the blue bags are covered once again.

I can't explain the closing of Seagrape Trail. There is no apparent reason that satisfies me.

Archaeologists are puzzled over the discovery of a Roman-era earthenware pot filled with oil lamps and bronze coins in the commune of Windisch, in the northern Swiss canton of Aargau...
Here is the link for the rest of that story.

This was one heck of a year. I can't believe that we are coming towards the end of 2016 already. Seems like just a few weeks ago I was doing the January 1 post.
The tide is going to be unusually high today. Watch the tide charts. The water level in the lagoon has not been low for months. If it has been, I missed it.
Happy hunting,
