Default Copper Casting In America (Trevelyan)

Tom,
it seems as if you and Gary aren't aware of anything but what's on Connor's
website in this question.
I know for a fact that Eric has had some of the information Mallery gained
by letting Keeler help him to the best metallurgic specialist there was,
actually still much more credited than most today.
I know also for a fact that Mallery's analysereports aren't in Connor's
website, no matter that it contain a lot of other interesting details.
As some reading this already knows Mallery's papers are preserved in
Keeler's deposit in a private Museum. Lot's of documentation as well as some
of the most discussed findings of Mallery and testresults showing beyond any
reasonable doubts that we are discussing casting and nothing else what so
ever.

I rest there for the moment. Eric hasn't had all information but some
essential parts of it.(not sent by me) I will go thru my discs looking for
an indexlist I know I have re. the deposit.
More later.

What about radiographs cited by Mallery? These have been mentioned
several times.


Eric,

Gary has discussed this several times. In essence, the
radiographs on Connor's web site cited by Mallery were
apparently not cast. What Mallery considered bubbles
characteristic of cast copper appear to be, with one exception,
*not* the type of bubbles one finds in casts of copper of the
purity seen in the artifacts.

The sole exception, the artifact labeled R666 (Riverside site
artifact number), or 55786 (Milwaukee Public Museum catalog
number--where the artifact is curated), does show the typical
porosity. However, I don't think anyone thinks that the
artifact is an example of intentional casting, but rather of
accidental or natural (e.g.: forest fire) melting of a bit of
copper.

OTOH, some of the radiographs clearly show annealing twins, and
linear voids characteristic of smithing.

This has been discussed before in this thread, perhaps before
you returned. If any of this seems new to you, you might want
to read the thread in Google groups.
