loupe d'acier

Tech/Engineering - Metallurgy / Casting / iron ore
French term or phrase: loupe d'acier
This is for a documentary about the fortified castle that is being built from scratch in Burgundy using medieval techniques and materials. We are shown them roasting some iron ore and the comment when it comes out of the furnace is, "On a passé une 30aine de kg de minerai de fer et la en sortie en matière brute, en **loupe d’acier**, on a peut-être une dizaine de kilos de matière."

I've found "bear" for "loupe" under metallurgy in the GDT, but can't find other references to back this up. Would be very grateful for help on this one, because time is short and I don't have enough knowledge of the subject to search very intelligently!

Explanation:
This dictionary https://books.google.ca/books?id=KYf3VtxsMeMC&pg=PA781&lpg=P... gives "steel bloom". Termium ( http://www.btb.termiumplus.gc.ca/tpv2alpha/alpha-fra.html?la... ) gives "lopin d'acier" for "steel bloom".

Explanation:
I am posting this answer on behalf or Alex Greenland, aka Bourth. He cannot post it directly because he is not a registered user. I have more confidence in this answer than in my own.

A lump of red-hot, plastic iron taken from the
puddling furnace for hammering or rolling.

une loupe est la masse ferreuse réduite produite en fin
d'activité d'un bas fourneau, d'une composition chimique
hétérogène et d'où on
tire le fer et l'acier par cinglagenote 1. Elle est de masse
variable, entre quelques kilos et quelques tonnes, et sans
forme particulière.
Elle peut également être obtenue par agglomération ou par
soudure de blocs de fer. Dans le bas fourneau, la masse se
forme également
par agrégation sans que n'intervienne l'état de fusion.
Récupérée ou travaillée sur la sole d'un four, la loupe
se présente comme une masse de forme approximativement
elliptique, même si,
étymologiquement, le mot dérive du franciqueluppa ou
loppnote 2, qui fait référence à une masse de matière
informe

Check out page 503 of Voyage Métallugique en Angleterre
(1839), which appears to use "balle" and "loupe"
synonymously (it is even
possible that the intention was to write "ball", in
English), here : https://books.google.fr/books?

iron ball / iron osmond


Explanation:
"Iron osmond" if you're sure that the Osmund Process, which apparently dates back to the 12th c., is what they're describing, or, to be safe, "iron ball".
French Wiki: "L'ouvrier constitue alors une ***loupe*** d'environ 10 kg en rassemblant le métal autour d'un ringard."
https://fr.wikipedia.org/wiki/Méthode_osmonde
Both "ball" and "osmond" are cited here:
