Silver Soldering

In ME, Tony Meek is currently describing the construction of his lamps for “Princess of Wales”. These little gems look exquisite. BUT! Will Tony and/or others with the “know how” please describe how to clean up after silver soldering. My silver soldering results in a most unattractive blackened lump which I find nearly impossible to clean. The photographs show brass components looking pristine after silver soldering. Discuss?>>

Hi There

Pickle it in citric acid after silver soldering.

Not sure why it becomes a blackened lump though.

Yup, dunk in acid and if that doesnt remove any of the scale use a soapy brillo pad – it makes everything very slippery but it cleans up a treat.  Also, if doing such delicate work silver solder wire is great stuff and it then means you can cover the entire job in flux to keep off the crud and not flood the job with solder. 

When i mix up the flux paste i put a drop (1) of hand soap into the mix, this makes the flux stick to the job and not run off when it gets warmed.
