Summary for latin metal question Discussion
The thread offers almost no substantive discussion beyond a metal question for Latin scholars, with the only visible clue being a reference to "Gaii Institutiones" and a reply attribution to Ray Kremer of Stellar Solutions, Inc. Because the excerpt does not include the actual question or answer content, no technical conclusion about the metal topic can be drawn from the source provided. The page appears to be a very short archive entry rather than a full Q&A exchange, so the safest takeaway is simply that the discussion involved a Latin-language reference and a response from Ray Kremer, but the practical metal-finishing advice is not present in the excerpt.

Q. Hello to everyone. I am translating from Latin into Spanish a Roman legal textbook written about the year AD 161 (Institutiones Gaii)
One paragraph states that: if gold (Latin word is “aurum”) and copper-bronze (Latin word is “aes”, and it could mean both) mix together, even though they alloy and cannot be separated (Latin words “deduci non possit”), each metal maintains its properties (Latin words are “utraque materia etsi confusa manet tamen”).
Could someone please explain to me the chemical meaning of the statement, considering the state of the art in that time and place. Could anyone tell if “aes” should be translated either as copper or bronze?
Thank you very much in advance.

A. Jorge,
Since I’m a metallurgist but not a historian, some further context might be helpful here.
It could be that they were trying to get at some sort of atomic or elemental theory, which is to say that an alloy still contains atoms of the individual metals mixed together, and is not in and of itself a new or different metal.
The old-time alchemists stumbled on a lot of chemical truths, but had no real explanations for them until much closer to modern times. I have no idea what the prevailing theories were circa 161 AD, though.
