I made a batch of CS last week ( my second batch )
All I did was run the the 27 volts through the silver in spring water 
(right out of a mountain run off.) for about 8 min..
It looked lunar silvery grey when it was new but now it has turned a 
wierd transparent pinkish purple.

Does any one have a clue?

The only thing that I am aware of being different from the first 
batch is I intentionally touched the two silver wires together( sort 
of like a welder striking an arc) before letting the generator run.
Both batches were in clear glass bottles.
