Brass Black

[Nirvana]

The product is used to blacken brass, since a lot of material in our kits are made out off britania metal I played around with this chemical.

Turned out beautiful, the final finished metal looks like true wrought iron.

After letting it rest for 24 hours it the surface is quite scratch resistant.

And what is the name of the product?

 

Never mind it is in the Title.... read James read.

Is it the Birchwood Casey Brass Black? If so I have used it and it worked well for me too. But like you point out it needs time to set before it's durable enough to handle.

Yes, it's Birchwood Casey Brass Black.

I find it curious and interesting that it works on britania metal.  But good that it does.

Mark,

Now I wonder what other materials it will work on.

[wefalck]

These blackening agents rely on redox reactions by which either copper carbonate (CuCO3), magnetite (Fe3O4), or selenium oxide (SeO2) are deposited on the metal surface. This would require a electrochemically less stable metal in the alloy. Whether it works for a given alloy probably depends on how much say copper is contained in it.

there are different products from birchwood and other producers for various materials.... alu for example.But even for silver pattina and gold.

Just got some brass black and its working well on my brass, much better looking after using it.

 

Ive been pouring some out into a small cap and soaking the parts in that, but im wondering if i can keep the used liquid and pour it back into the bottle after soaking parts in it? Or will that ruin the unused stuff in the bottle?

 

[Jim Rogers]

I pour mine in a plastic container with a lid and use it over and over and over. No worries

[mtaylor]

Trig,

I keep it separate so not to contaminate the "new" stuff.  I also do what Jim says..  use it over and over until it stops working.

[Trig]

Alright,thanks.

Wasn't sure if once it reacted that was it spoiled or used up, good to know.
