Hello
I made some experiment. I used 2CB (powdered 2cb Hbr).
Part 1 of experiment
1. 2CB Hbr (2,7g) was grinded to small fraction in coffe grinder
2. 2,7g od 2CB Hbr was disolved in 100ml of warm water (about 40-50C)
3. About 8cm paintbrusch was used to put slite brown water on watercolor 360g/m2 A4 paper.
4. The proces took a while. I put water on paper, waited few minutes to dry, put next layer. Lest say it took about 30min.
5. Paper was ready to use next day. It was dry and i can feel that it was little bit more brown and not so flexible as before.

Part 2 of experiment
1. Paper was grinded on small fraction in coffe grinder
2. Paper was placed in 500ml glass chemical filter
3. 100 ml of warm water was placed in the filter. Clean nice water was collected.
4. Another 100 mg was placed one more time in filter and water was one more time collected.
5. I am sure that inside paper there was more or maybe the solvent used can be better - if You can sugest anythink please do it.
6. Collected 200ml of water was placed on glas flat container. I left it for 3-4 days.
7. Whan all water evaporated i could collect 2,1g of nice little yellow little brown cristals (clean 2cb hbr).
8. The cistals look nice, i tested them, working well, and it was tested - its 2CB.
I am sute that this method can be corrected, maybe better solvend made.
I am also sure that if i will keep the paper and grind it one more time and repeat water extraction there will be more 2CB Hbr.
