From Non Toxic print making

Washing plates and Safe Disposal
Traditionally, etched plates which have toxic residue on them have been washing in the sink, discharging waste into the water system through drains and sewers.
Electrolytic solutions do not affect the aquifier (the water system) if certain precautions are taken.

COPPER SULFATE SOLUTION
However, it is recommended that plates that have been etched using copper sulfate solution be wash in a tank with water and iron filings. The reason for this is that copper ions are converted quickly and easily into metallic copper which is easily disposable and rendered harmless by contact with iron filings. Use a plastic tank or flat tray into which the etched plate will fit comfortably and which is large enough to contain plenty of water. Place some degreased iron filings or a thin piece of steel wire wool (the kind used for polishing that you can buy at any hardware store) into the tank. The tank solution will gradually become yellow in color and it is at this state that you can filter the solution then dispose of it down the drain. The plate can be removed from the tank and rinsed with water in the sink.

Also you mention "100 grams per liter"... Is that 100g of copper sulfate?
Yes Copper sulfate will work with brass
Yes 100 grams per liter

I wanted to thank everyone for posting all this useful information. At present moment, I have my first piece....an acorn cap...in the blue bath solution. It appears to be growing copper as I type this post. Prayers are said and hopefully in am I will have electroplated my first specimen. The wheels of creation are going full force in what can now be electroplated.

I don't have a reason other than my gut but I would use the softer flexible tubing.

I know that hardware store copper comes in 2 or 3 types and I think the roll tubing has the softer stuff and I think the purity is higher.

I believe they add alloys to make the ridged pipe stiffer.


But I have been wrong before and I am pretty sure I will be wrong again.
