How to make Ferrous Chloride


Brownie

Recommended Posts

Hi folks,

 

I'm looking for a way to make ferrous chloride. I'd like to try using it to lightly tarnish and give an aged look to nickel plated metal parts. I have used ferric chloride (etchant solution) both full strength and diluted with mixed results, perhaps due to differences in the nickel plating.

 

Someone told me that ferrous chloride works better and yields more consistent results. I've read that it can be made by adding steel wool to sulfuric acid. I'm not a chemist, so I thought I'd ask some people who know more about this stuff than I do. I'm wondering what ratio of ingredients I would need and how I would proceed safely to make it.

 

Perhaps there's a better way to make it? Or maybe something that would work better that I'm not aware of? Thanks:-)
