hunter12Pink color normally means too acid but not in 100% of cases also could be impurities from your freebase, check the PH should be around 4 anyway I dont see any precipitate in your pic.

Is there some thick material appearing on the walls of the beaker during stirring?
If there is. Use a glass rod to scratch the side of the beaker. Will help with crystallization.

qwe111This is how it gets during stirring but no precipitate after

Try 150ml h2O+80gr tartaric once dissolved add the freebase with heavy stirring until solid mass formed could take some minutes.

btcboss2022Ok thanks il try that, il come back with results

hunter12On my experience I think it needs more time stirring it's getting thick and finally solid.

I just added a very bit of sodium hydroxide solution about 5 grams and its showing crystals. I dont know if i did the right thing by adding sodium hydroxide.

hunter12You simply increased the PH, check the PH now to have an idea if you are in the right way.
Honestly I never had this color in that process and I did it hundreds of times in different ways, amounts, routes...but maybe is right you will see it.

btcboss2022The PH is at 5

The PH is at 5

hunter12Could work, update us when you finish the process thanks.
