People say its EK's fault if they had impure Copper, but how are you to test an entire block of Copper for impurities prior to the plating stage without melting the block down?

Just wondering as I have no idea about said testing methods.

As I've been saying all along, I think this situation is obviously are lot more complex then people first thought when reaching for the pitchforks, a degree of benefit of the doubt should be applied in such a situation until a further response is made in regards to recent developments.
