As far you could get with it if its dirty old solvent, is use it for rough pulling as resources shouldn't be unnecessarily wasted, safety for all(including yourself) is presidentially first. If you feel you want to dive into a act of alchemy set and setting is prime. You need to have place where the people who will inevitably be around not be startled is pinnacle cause it takes while focusing on becoming a chef chemist/shaman healer for yourself and only those who will be in benefit of contact.
It takes awhile to build up patience and caution, it helps
a lot after dissolution. If you got that down then the next sentence should read. As meditative thought progresses your life is going to be grasped at what humans can move their Chromosomes to read life through the next wakening exogenous moments. First you must be very sure of everything your imagine can conjure so when the situation dealing with freebase occurs, its a
tool not a broken law in the universe you think to deal, your in the right place when it can be both and, a vibration in time that can show answers to questions :3. Imagine the build up to a sky dive, lots of factors dealing with equipment to weather is addressed. The place to pick is one you feel safe enough for a nap at, but compared to the skydiver this will have a much different impact and experience than the skydiver.
To your question it should be fine to initial pulls with it, though I must say re-extraction with newer solvent is needed and you'll be able to solidify better and purer crystalline structure for clearer flash.
Good luck if you attempt, it takes courage to venture but this territory one cannot get over once known there's a pass.
