i was woundering how would i make powder after im done with cold water extraction im useing perks (oxycodone)
the best thing you can do is get the liquid in a deep bowl and use a hairdryer on it on a warm setting. it sound bonkers, but it is very effective. dont let it get too hot though as no opiated likes heat. once youve got the water down to a much smaller amount, put it into a shallow, wider dish and alow to evaporate by its self. not in the sunlight though.
91% isopropyl alch. works the best it evaporates much quicker. (thats my alkaloid isolator of choice for hash oil extraction!
