Forgive the ignorance, but would the manganese have been used in the
glassmaking, either as colourant or decolourant? This s the only
archaeological reference to it I can find. And if not, what would it
have been used for?
>Does anyone know about the mining of manganese ore (pyrolusite or
>rodochrosite) in Roman times or the presence of these ores on
>archaeological sites? Are their any chemical analyses available?
