There was a discussion started this weekend amongst some of my group about a line from Markham's Soldier's Accidnece:

[Nathan Robinson]

[Jean Thibodeau]

Sanguine: In French, pastel crayon made from red ocre, a reddish orange colour.

Also sang is BLOOD in English: So blood colour.

The related word " sanguinaire " means " blood thirsty " in English: Sanguinary.

From my old LAROUSSE dictionary.

Thanks guys, I was assuming the "Russet" color mentioned was a type of browning, but I have never found any references to existing examples of this kind of technique. I was assuming the "Sanguine" finish was a painted red finish, because I have never seen or heard of an example of browning or heat treating that leaves the metal in a reddish color. Anyone who has more metal working experience than I do know anything about getting that kind of color?

Again thanks for the help!

There are many different chemical formulas to patinate pieces, to a desired finish. Using a vinegar and oil with heat can produce a reddish brown that would qualify quite well. The Browning that one does to guns is similar and by adjusting the elements one can get quite a range of colors.

Once you get into Bronze there are whole books on coloring with patination.

I know I have read some recipes from the period for this type of thing but can not remember which reference they were in.

The beauty of these finishes is they are basically corrosion that has been arrested at some point. Thus one worries little about it getting scratched or starting up again just dose it with oil.

Is there any evidence of heat or chemical bluing/browning/blackening of armor in the late 14th to early 15th centuries England or English controlled France? Or was all armor in that period and location in the white or painted/fabric-covered? If so, how rare was it to have?

[Randall Moffett]

From my work at the forge all armour that goes in comes out darkened. The real question is what do they do when it is out. Would they leave it blackened? From what we have it is hard to say. People have cleaned much of modern armour (We have a bright 17th century 3/4 suit that was stripped of its blackness). The reason I think much was cleaned off was that the items that do exit still are bright for the most part from 14th and most artwork has it bright looking. Now there are black looking pieces of armour in artwork from the 14th so it could go either way.

My guess would be that as armor developed the white finishes were more of a high status upgrade. More time to finish the armor and more cost in upkeep. Also it would skew the art work of the period to show more white finishes as the art of the period is often not focused on the lower rungs of the society, even to the more median man at arms. Kings and Saints type of thing.

As more armor was produced the white finish would become more economical as production and supply filled demand and efficiencies in the market took affect. Also fashion creeps down as well as up so those aping a higher status would go for the polish upgrade. There are many armors in collections today that has colored or worked finishes that are now bright steel. Some conservators in the Victorian era ground them off thinking they were embellishments added later as opposed to what they actually wanted. They were skewed by their own preconception of the knight in shining steel as opposed to a colorful check pattern or interlaced lines of bold color.

There is evidence that on the lower end things were left black and even with a hammer finish. munitions grade armor. If it were to be covered with fabric even more so as no one would see the finish.

Hey Chris

I will try to get my brain to spit out a reference if I can that kind of stuff usually pops out about 4 days after I try to think of it and when I am in the middle of something completely unrelated.

If I do I will be sure to send it on.

Steven-

Here's what we've done:

I got a nice fire going with a mix of charcoal (commercially bought) and oak. Once the flames die and we have a good center of coals, I took a grate and set it on top of the coals. I then took a very well cleaned and polished up buckler and applied a thin coat of boiled linseed oil to it. Enough to make it look glossy with oil but not enough to puddle. I then set the buckler (oil side up) on the grate. I didn't time my piece at all but eventually as the metal heated up the oil turned from its normal slightly yellow color to brown, then dark brown and finally black. After it started getting a glossy look to it, I took it off of the fire and gave it a light wipe (using heavy gloves) with a linseed oiled cloth.

For the helmets we did the same process except we hung the helmet close to the fire using a cooks tripod and filled the bucket with coals. We found that just placing it over the fire didn't get the peaks of our helmets hot enough.

The finish has lasted with a few nicks here and there for the last 3 years. I'll try to get some pictures this weekend.

Yep, we filled the helmet with coals. All the way up so the whole thing was heated. The buckler took around 15 minutes once the fire was going if I remember correctly, the helmet took a bit longer.

I found this blurb on the Met's webstie (http://www.metmuseum.org/toah/hd/dect/hd_dect.htm)

I've been horribly remiss in posting my attempts at linseed blackening, so finally here are some pictures of my attempts.



Buckler with 3 years of light use. The method used for this one was to paint on some boiled linseed oil with a cloth so there was a thin layer all over the surface. I then put the buckler on a grate over a charcoal fire and heated it until the color was one I liked.







Burgonet that has a devotion to St. Michael scratched into the blackening. This one I did the same light coat of boiled linseed oil on but hung the helmet from a camp tripod over a charcoal fire and filled the skull of the helmet with burning coals. The effect was good, but the comb and part of the brim didn't get fully black. Instead they remained a dark brown. You can sort of see the scratched in devotion to St. Michael in the last picture.




The last is an old starfire dagger that I had lying around. I stripped it of its wrap and threw the hole thing in an oak and charcoal fire. Once it was "good 'n' hot", I took it out with some tongs and dipped it in a bucket of linseed oil. You can see some bubbles and debris that was stuck to the blade when it was dipped in the oil. In hind sight I'm probably very luck the whole bucket didn't catch on fire.

I hope that helps visualize what I was describing.

Chris, thanks for posting the blackening recipe. I had a gut feeling that there was something simple, and that was it. Everything else I've seen involves fairly toxic chemicals.
