Giannis vs Polinik on the color of bronze :)

[Giannis K. Hoplite]

The best availlable helmets are made of phosphor bronze, because their makers cannot find better material in big enough pieces easily. It is also a matter of taste, but many people (me included) prefer it to commercial brass, which neither has the correct metal allow nor a closer percentage of copper to the originals than phosphor bronze.
There are better alloys out there, but too difficult to find and especially in sheets of a reasonable size to make helmets and armour.
