Swim is using this tek...
Take rue, powder it, place it water with small amount of acetic acid (distilled vinager) bring to simmer, cool and strain, repeat at least once, on the last batch, add the strained water hot and dissolve a good quantity of non iodized salt into the water, place in fridge/freezer (watch it so it don't freeze and break your container) and cool down to really cold, brownish orange flakes will percipitate out, let set in fridge until flakes settle to bottom, pour off excess liquid, then filter the rest through a coffee filter, wash with cold salt water, dry and scrape off the powder.

In the end, it says that to cold wash in salt water, but swim was wondering if you took the sparkly dirt and and boiled it again in salt water and refilter then cooled if more pure crystals would form on the bottom? Or would that process damage the product you already have?

Any insight is welcome...

The gunk (which SWIM happens to have sitting in his fridge right now, lol) is very impure.

The best way to purify is to freebase.

Take the salted-out junk and dissolve with fresh vinegar. Anything that does not dissolve will be impurities.
The mix can be filtered to a clear solution now. Through mesh strainer, then cloth, then several coffee filters.

Next the PH is raised once the PH is above 9 then most of the harmine will begin to precipitate phlux's telepathine tek explains it, though if the PH is put straight to >11 both the harmine and harmaline will precipitate.

SWIM uses ammonia because it works really well, though sodium carbonate could work too. Once the solution is basified then it is like warm naptha saturated with DMT, crystals will stick to the side over several hours. The basic solution is poured off and crystals dried and collected.
