I should receive the nic in a couple of days or so and I'll put it in the freezer.
If you're getting 100mL of nic base, don't put all of it in the freezer. Freezing nic base is more for longterm storage. You should probably put whatever amount you'd need to make your eliquids for a month or 2 at least...in a small glass bottle and keep it with your DIY supplies. As long as it's in a pretty cool and dark place, it'll be fine for that long. Or, you can put that bottle in the fridge, and allow it to reach room temp. each time, before you uncap it to use any. Split up the rest of the 100mL into similar sized bottles, so you can remove only 1 at a time from the freezer, as needed. The rest just stay in the freezer until needed.
When you take a bottle out of the freezer...allow it to come to room temperature also, before opening the cap to use any of it. Otherwise condensation will form inside the bottle, and that's not a good thing for nic base.
