Here’s a related question about copper,…
I have started to use citric acid instead of safety pickle or other
stronger acids, to reduce environmental impact; I felt pleased with
myself for a while, but have been informed now that the acid content
is less of an issue than the quantity of copper being flushed into
the drains when the neutralised pickle is discarded.
As Copper so beautifully plates silver when a student accidentally
puts steel tweezers in the mix, I wonder if there is a way to use
this method of extraction to make the spent pickle more friendly to
the waterways?? Obviously I don’t want to be using my silver for
Any ideas or other suggestions?
