Typical mean values for the higher manganese samples were around 0.05 wt% but individual analyses peaked at 0.1% and slightly above.

Subject: Re: Manganese in bloomery process
Thanks for your answer David.
I must precise that, in my case, even if we are in the 14th century, there
is no doubt that the forge is a direct process bloomery due to his location
in the Pyrennées, where the indirect process is not installed at this
period. Moreover, slags are typical of bloomery process.
I have to re-read you work .... but can you precise what to you mean by
"high Mn in metal" (how much ppm ?). Is that indicated in your paper of
Norberg ?
