Pamela, we leave "masse" in French below—do you have a sense of what is meant here? Can you craft the text for an editorial comment? Or do you want to leave this unaddressed?

@Pantagrueliste Can you please look at the DMF on masse: http://atilf.atilf.fr/scripts/dmfAAA.exe?LEM=MASSE1;MENU=menudmf;AFFICHAGE=2;ISIS=isisdmf2015.txt;MENU=menurecherchedictionnaire;OUVRIR_MENU=1;ONGLET=dmf2015;OO1=2;OO2=1;OO3=-1;s=s13032ef0;LANGUE=FR;XMODE=STELLa;FERMER
It seems to refer to the amount of metal used to make a vessel or object--a technical term for metal working. See within the entry especially: Masse de and Une même masse Thanks
