Thread: Pickling brass after silver soldering.

19/07/2020 19:05:03

In the world of silversmithing, the traditional pickling method for silver, gilding metal, brass and copper in order to remove oxides and the borax flux was dilute Sulphuric acid.This was heated in a lead bath to speed the process. Then 'safety pickle' a Sodium Hydrogen Sulphate powder (available HS Walsh, Kernowcraft etc ) was introduced and used widely in schools colleges. The user added water. For small items it can be used in a slow cooker! I now put water in the cooker and keep the pickle in a glass jar in the water as I've got through a few car boot purchased slow cookers over the years. Needless to say that good ventilation and eye protection are essential. Retrieve items with plastic tongs ie do not use fingers or steel tweezers

I'm not sure of the exact composition of 'Sparex 'which is similar to 'Safety Pickle' but when I worked in the US, the metalsmiths were keen on mixing in some Hydrogen Peroxide at times, to avoid the coppery surface which appears on Nickel silver and brass when pickled. It was very effective.
