And that, of course, remains an interesting question. My owh suspicion is that
those smiths were using methods that differ from our own. Perhaps tools didn't
allow as efficient working, so metal wasn't being "moved" as quickly as with

Arguing is pointless? for its own sake? yes.
Im not trying to argue with anyone, As I said Im confused ie not clear
if you follow, how the LaTene smiths made an alloy of copper and tin,
and were able to forge out an ingot to less thn a MM over such large
areas, based on the analysis ofthe original metal.

You are wrong, and I pointed out why.
Arguing with you is pointless.

XRF analysis basically looks at the intensity of a selective spectra emitted by
the sample's surface, with any given element responding differently. With
computer processing, it then is possible to derive a quantitative analysis of

I wonder if the piece was analyzed by X-ray Fluoresence? Perhaps that
yields a volume-type ratio? Or did they physically 'assay' a piece?
I dunno

1 unit volume of tin plus 9 units volume of copper don't result in 10 units

copper/tin alloy if evaporation and splatter losses could be prevented.

Why does this confuse you, Ted? It's clear enough. The ratio is slightly
approximate, Perhaps it varies from place to place in the item. But it's
between 9 and 10 percent tin, and 90 to 91 percent copper. Nothing there should
be confusing. They state there are trace amounts of arsenic and lead, but at

ted.fra...@virgin.net (Ted Frater) — Fri, 26 Jun 2009 02:10:41 UT

Ill reply on the basis of memory which is still resonably reliable!.
From what I recall, there were minute ie less than .05% of arsenic and
lead in their analysis.
Now im still confused,because if the analysis is by percent, ie 9 to 10
parts of tin to 90 to 91% copper.
Now this has to be by volume, ie 1 part of tin to 9 parts of copper

Check these definitions. Last I heard, Rhyolite is an igneous rock. Though
silica rich, it is not jasper, nor related to it. Jasper, like other
chalcedonies, is a sedimentary material. Now, you could have rhyolites with
voids, bubbles, etc, form, which later would have jasper or other chalcedonies
