Roman Dagger Restoration

ALEX · 24th February 2020, 09:38 AM

Here is the ARTICLE LINK that allegedly shows before and after photos of a relic Roman dagger. The found relic looked like a mass of corroded and deformed iron, and the end result shows most decorations intact. This is astonishing, and took 9 months. I am curious how was it possible to remove such advanced rust without damaging the inlay?

Wow! Wouldn't have thought it was possible.

That is almost unbelievable! I assume that for the 9 months it was soaking in some solution which dissolved the rust without affecting the original surface. Is the blade still intact? Can it be withdrawn from the sheath? Amazing.

Unbelievable indeed, the blade is intact and fully functioning... and it comes with the original belt!

An electrolysis bath can remove rust very efficiently; and when the rust has gone there is no further degradation to the iron that is revealed.

Check out the video at the bottom of this link of Vegard Vike's conservation of the Langeid Sword:

I think this kind of work often requires mechanical cleaning like his micro chisel.
