The best way disolve just head under water. Slowly add some ammonia and poef
all milky white… then add some little more ammonia. Take a metal spoke or thin iron stick
and just go up and down fast in the middle of the spoon
(not rvs) old 70-80 kitchen spoon for soup or jus. Keep moving the stick in the middle.
Suddenly you get gleuish sirope and while keep moving fast short movement you feel the resistance getting stronger until the mass is getting rock hard on the stick.
Then you can immediately Shouf it of
Or break as it’s really really rock hard using fischscale grade.. 15 years I did use heat but Hispanic learned me this recently and this is the way for freebase..
