merkin, it is looking good to me. Those sticky xtals in the 3rd picture look like the kind of product we can get. 15mg/g of citric will dissolve into ethyl acetate with enough shaking/time. The cloudiness disappearing is a sign that mescaline citrate is precipitating.

You can shake a few more times to make sure the citric acid dissolves if you are still seeing what look like granules. With time and shaking the liquid should become completely clear.

You may have whole plant, not sure. When I used whole plant I had to add 20mg/g (mentioned on the TEK's xtalization appendix). Extract from whole plant was more difficult to xtalize.

The extract looks a little greener that I would expect for cold extraction - Did you also use ice water so the paste would be cold when extracting?

After the solution is clear, you can proceed with catching the xtals and seeing if any are stuck to the walls (I think I see some, they can look very transparent). If you wash with a small amount of fresh ethyl acetate (jar walls and filter) most extract color should be removed. You can dissolve the product in hot water and let it evaporate slowly, you should get needles that way.

Would be very interesting if you report on the yield. If it is low you can try another pull on the spent paste.

I'm thinking we should add a microwave step before pulling. Also add a salt to the paste so it can be at freezing temps but not form ice and remain a paste for extraction. I'm getting a lot easier/cleaner xtalization with these updates (it's not really a lot more work). TEK can work without these changes, but with these updates it should be more robust in general.
