I just noticed a strange result with slow crystalization: I'm seeing crystals form AFTER the 24 hours.

My last two extractions have used slow crystalization with 5mg citric acid per gram of EA. Exactly 24 hours after dropping the acid I filtered the EA into another jar and stored the used EA. However this morning I took a look at both jars and noticed that they both still have crystals. Beautiful white needle crystals. It looks like quite a lot. The microwaved/slow crystalization appears to have less crystals than the non-microwaved/slow crystalization but I am not sure.

The first extraction I did with fast crystalization did not do this.

Has anyone else noticed this? Not sure if I am doing something wrong or if this is normal. But I'm glad I didn't neutralize the used EA immediately after or I would have missed this. If it is normal perhaps the tek should be updated to wait longer than 24 hours?

I'll try it. For now I'll stick with the "standard" process a few more times, just because I worry that due to my inexperience I may simply be making some mistakes somewhere.
