Salvete friends,
my last work.
This helmet montefortino is preserved at the museo Fantini of Monterenzio (Bologna) with decorations made Bump.

Reprodution: Material: iron thickness 2.5 / 2 mm. and brass plate..
More pics.


Of course I have to work hard on Bump, is the beginning.

Nicely done!

That is an interesting Helmet, the way the fastening studs are done is very clever!

The Deepeeka Celtic Montefortino has similar fasteners, but sandwiched between to layers of iron sheet.

Hmmm, and I almost ordered that one too :lol: It is a more protected technique though......JMOT

Nice.
Stefan has made a similar one in combination with a bird

Great work.

Do you have trouble with the metal where the iron contacts the brass? I've had to deal with that, as it seems to want to rust at that point more than at others. Electrogalvanic response, the big boys tell me. Rust, says I.

How do you deal with that?

You can't avoid rust in those spots. As long as the iron is into contact with the cupric alloy, the iron will corrode (the less noble metal of the two will corrode). You could for example tin the iron or apply a varnish to it. But that won't be very authentic...

Perhaps you could avoid the corrosion of the iron by putting it into contact with an even less noble metal like zinc. I know they put blocks of zinc on the iron hulls of ships to avoid the corrosion of the iron (the zinc bars will be corroding instead, being less noble).

Do english speakers even say 'noble metals'? Probably not :lol:

Vale,

We do! along with Noble gases etc.

Ship building was for a long time plagued by the electrolytic reaction between the iron rivets and the copper 'roves'. That was before they understood what was going on!

We still use zinc anodes on hulls, especially on oil rigs. Some more exotic
methods have been experimented with. I recall being involved with one that failed its first test when I first started offshore.....

The copper rivets are a problem on iron but if we treat the helmet during hot-working can make good against corrosion.
The original piece that I showed you had the gold foil and believe that the rivets were iron as can be seen also in the picture.

WOW! Those are a couple of fantastic looking helmets! Great job on both of them.

maybe a stupid question... but...
this is looking as very fine, luxurious helmet. Is there any "normal soldier" monterfortinos made form iron or they were all from brass/bronze?

@ Ioannes.
It`s surely a very early helmet, maybe 4th or 3th Century BC, and of celtic origin. The Celts made very elaborated helmets, for there ´normal´soldiers too, from brass and from iron. Whereas the early romans of the republic manufactured only brass helmets.
