I have a question and I hope someone can give me good answer for this or correct me.
So Romans were able to make so thin iron and steel sheets which have quite similar thickness no matter if found in Brittania or Balkans which is on average 0,8 - 1,4mm. What's more, they lack of any forging sings on the inside (why would Romans clear them if the left for example hammer signs on helmets?)
As far as I know, Sim and Kaminski tried many various hammering techniques to achieve such thin sheet without signs of hammering.
They fail. They were able to get 4mm sheet with marks after forging becasue. Sometimes biggers, sometimes smaller, but always.
Finally they came up with idea of stone/metal rollers which would work like a quern by using crank (which was know for sure in IV AD).
It was the only way they were able to receive thin sheet without ani signs from hammer.
Of course it's jus a theory becasue we don't have any evidences that romans had used such rollers.
So here is a question. Are you familiar with any other way, theory how Romans could get thin sheets in a efficient way which can provide sheets of a 0,5mm thickness?
Even if we assume that they could use such rollers like Sim and Kaminski around III/IV AD, how did they make segmatatas before?
