Hey man good luck.

---> Syringes work well to separate the layers from each other, eye dropper works well when you only have a little bit left.

I noticed you're gonna for the evap method. A good tip I picked up from someone on here is to stretch cling film over the top of your container and prick holes in it to let the naphtha evap from. This minimises getting dust and other crap mixed in with it all.

There's no 'set' amount of pulls you need to do with 100g, keep pulling for as long as you can to try and get the maximum out, but 4 or 5 should do it.

If you want another tip, warm your naphtha before you use it to increase the yields.

The best way to do this is by making a heat bath; never directly heat it or have naked flames near it. Boil a pan of water and sit your container with the naphtha in it for 15 mins. My friend uses a pyrex jug, other ppl use a mason jar.

I would definitely recommend investing in a pyrex jug or two if you have one, guarantees it won't crack.
