Here are 2 pics of  the same run, one with flash off, one with flash on, both shitty photos, but best i could take with my phone.  This is a 30g run of material that should yield somewhere between 1.4 to 1.8%, using sodium carbonate washed solvent and passive crystallization. The product was filtered yesterday and was clearly a combination of needles and powder, the powdered component was bland, without bitterness, but acidic.  Total yield was 0.662, 2.2%.

The quality of the wash makes a difference, this was from one that was problematic, causing me to change my approach, to one that hopefully will be much better.
