Hi y\'all. I thoroughly enjoy this forum and thanks everyone for keeping it fun,civil and informative.
Just bought my second Chem set and I just had to delurk to clear up an issue that had been bugging me for a while.
When I discovered this site a few months ago I went hog wild and bought half the pheros available (Chem set, PIm, AE, PF, TE + got free SPMOs). After a few days of playing around with the Chem set I hit a really effective mix and that meant the other pheros were immediately reduced to step-child status. The Chem kit pheros were clean smelling and I made small batches in those little cologne sample vials that you get at the department store until I got what I liked. Just for reference, at the time I felt PI was \"somewhat effective\".
Lately it seemed as if the Chem set pheros had lost their zing. I went through a few possible explanations; I had become used to the effect, or maybe my body was compensating for the pheros etc. etc. But when I pulled PI and AE(stinky!) out of the dresser the effect seemed pretty strong.
This is puzzling. Now Chemistry was never my strong subject, I was chased out of class a lifetime ago never to return. But my intrepid brain has ignored its inadequacies and coughed up a theory. If I remember right seed crystals in a saturated solution can cause the solute to drop out. I had noticed crystals in the Chem set solutions. However, since a couple of posts said this was not a problem, I ignored them. Now they have gotten bigger and seem reluctant to get back in the solution even with added EtOH. Just got my second Chem set, so I\'ll know soon if there is a difference.
So what say you Oh Lords of Chem ?! Anybody with the same experience ? Theories ?
