My friend has had problems with STB extractions with this mimosa.

The naphtha sucks up some sort of red coloring and it stains the xtals.  Nothing we've tried can get rid of it. It's not sediment, but is actually in solution.

He's working an A/B now, so hopefully this issue won't happen with that extraction.

I'll give some yields when he is done and hopefully shares his final product!
