Well, another bump and yet another TA novice summarizing the process lol.
I received the Rustica and did exactly as follows, just as instructed in this thread at least as I understood it:
1. Warm the Rustica in a shallow pan of very hot water (like 200 F) -- it does melt into a liquid
2. Add it to your mixing bottle and mix at 10% Rustica, 45% PGA, 45% PG
3. Warm the resulting mixture in the shallow pan of very hot water
4. Shake, reheat, shake, reheat, etc. A few cycles of this seem to do the job.
The Rustica does mix in and the result is a black looking mixture (the "black mix") that must really be a very, very dark green because the residue on the sides of the bottle is green. The resulting mix has a very pleasant almost floral, sweet tobacco smell.
As another interesting result, the syringe used to measure the Rustica is now labeled as dedicated for TA -- it will never come completely clean no matter what I rinse it with lol.
Next to taste it. I plan to start by adding it to a VZ "tobacco" juice I mix at 3% of the flavoring. I assume I start with 0.5 % of the "black mix" and go from there? The VZ tobacco is an extremely light tobacco flavor, almost hard to taste because it is such a light flavor. I am hoping the TA will really punch it up and also allow me to taste what the TA adds.
