How is he supposed to identify the impurities? Not everyone has a gas chromatograph in their house. He said his concern is
unknown impurities.
I apologize for taking the side of the underdog here, but I don't see anyone yelling "fire!" He just says he was upset that the original threads were locked, he investigated a bit further, and posted what he found, taking the time to take pictures even. I have no problem with him.

He is definitely not making it up... I bought some K2SO4 from Greg Watson and that is exactly what mine looks like.
I never really was comfortable in fact dumping this:

I almost feel dirty buying these "controversial" (
