Yes,
The zinc content will drop if you heat up brass to use it in casting. However, I was not discussing heating up brass, I was discussing the formation of the alloy. I never said that zinc will not evaporate. All I said was when mixing two liquids other things go on that give rise to the compositions people obeserve. "Boiling away" is one thing, but there are others.
I also do not care for the characterization that you deemed necessary to explain to me the origin of the Roman civilzation by attempting to enlighten me that the Romans were not dropped onto the seven hills. I was born in Italy and I can assure you that I do not need an anthropology lesson. All people have lived in a particular place in time for generations. However, in historical contexts we do give cultures and civilazation finite times. The birth of Rome 753 BC the fall of rome 5th centruy AD. Furthermore, I did not say that the Romans had to re-learn anything. I merely pointed out that it is part of human nature to re-invent the wheel many times through no fault of anyone in particular.
Again, I never said that the Romans or ancients made alloys in the way that I described. I was suggesting an efficient way that such a mixture could be obtained. Unless there is someone out there with a time machine to prove otherwise, most reasonable applications (such as I described) are possible.
