Very nice performance, thank you. 

Your Saint just gets better and better.

STAY SAFE

 

A model shipwright and an amateur historian are heads & tails of the same coin

current builds:

HMS Berwick 1775, 1/192 scratchbuild; a Slade 74 in the Navy Board style

Mediator sloop, 1/48 - an 18th century transport scratchbuild 

French longboat - CAF - 1/48, on hold

Colour of low battery guns

 

The low battery of the Saint Philippe is the only bronze one of the ship, which poses the problem of its color. Indeed, bronze contains copper, which can give several varieties of grey green by corrosion in a wet environment

 

To summarize, in the presence of water charged in CO², the grey green formed is copper hydro-carbonate, which shoots frankly on the grey-green, as its name indicates. In contrast, in the marine environment, salt from spray forms a copper chloride, which rather pulls on the greenish-brown

 

For model making, there is the possibility to soak the cannons in water with added cooking salt, and vinegar to accelerate the reaction, which is nevertheless very slow. or ammonia vapours (faster, but very toxic)

 

There is also the satin paint, with an exact color difficult to find

 

Finally, it remains the solution to allow the natural aging of the brass, which will brown slightly over time, and lose all alone its glittering aspect :

For other batteries, iron made, the classic tourmaline, or browner, works well and fairly quickly since brass is an alloy containing zinc that blackens on contact with selenium salts (a bath of fifteen minutes is enough to blacken the brass)

 

I admit that I do not know what to do, since the model is made of natural wood, I am wary of painted or stained accessories

 

I’m interested in your opinion

 

Thank you in advance

Thanks Mark

 

Much preparations can be found on line

 

For fast darken effect on brass (selenium) :

 

Brunisseur de laiton

For more slow grey-green effect on brass (unknown composition I hav'nt tested) :

 

Patine vert de gris pour vieillissement du laiton

Before, the piece must be well cleaned with acetone

 

After, a stop vernish can be required, I use simple water, and finish with a light polish by smooth clothe

I think that the best for these guns is the natural unvernished brass, which will become weathered alone  😀

 

 

That does take time to happen but yes, just make sure there's no fingerprints on the guns.   As it is, your method looks very good to my eye.
