The best crystals I ever got were by accident.

I normally get small fluffy powder like crystals with freeze precip from naptha using mhrb.

But one time, i left some spent naptha in glass having finished the process.

I had put cling film over the glass so it wouldn't evapourate, with intentions of re-using it another time.

Anyway, i forgot about it, and the cling film must not have been airtight, as when i came back to it, it had all evapourated, leaving me with a nice nugget of clear, thin shard like crystals, covered with a layer of orange oil. I think it was about 200mg
