My Menthol Crystals (2oz) from eBay came in today, and Wow! they were triple wrapped and I could smell them strongly the moment I opened the first envelope! Everyone's right, just like Vick's Vapo-rub. I mixed up a quick batch of the recipe listed at the top.
Here's the changes I made: I thought using the roller directly on the package might make tiny little holes in it, so I put on rubber gloves, got two big pieces of wax paper (parchment paper might have been a better choice - I hope no wax got in it...) then I took a small estimated amount of crystals from the bag, layed them on the wax paper, put the other piece of paper on top of that, and rollered that, crushing bigger pieces by pressing down on them directly with the roller, and periodically lifing one wax paper piece, brushing the caked dust off it, and moving the middle back into a pile. I did all this slowly because I've heard the dangers of breathing in the dust, getting it on your eyes, etc. Once crushed, I used a folded piece of paper to scoop it easily into the syringe until it was at 3.5 ml. I didn't have a spare 10 ml bottle (new at all this) so I put it in a screw-lid container with the PGA instead of a 10 ml bottle, with the idea of using a dropper with that. I followed all else as described, and it turned out as expected.
I sniffed it, and I could smell the Menthol prounouncedly more strongly than the PGA, which gave me an indication of how strong it was!
To try it out, I added 10 drops to about 6 ml of a Marlboro VG/PGA/VG/PGA mix I had made up and liked. It added quite a
throat hit, and discernable Menthol as well. But I like a stronger Menthol, so I will probably add some more (a few drops at a time) until I hit a flavor that works for me.
I absolutely prefer this to the mint/mentha flavors I have tried. They are fine for what they are, and certainly had throat hit, I just have been wanting my Menthol; I'm a former Menthol smoker.
Thanks so much for the great recipe!
