Thanks Loveall. 

For now, I’ll focus on trying to find the best way to get those pretty white needles in my filter, with the tek as already specified.  I have started a 4-way side-by-side (w/wo microwave, w/wo chilling), using 3 powder sources, so 12 runs. I’ll post results here, if i don’t screw it up too badly.

Re: EA defatting of outer green, what’s the general approach?

Re: Sending samples, how safe is that? Or, how does one limit risk?

Thanks
