Menthol crystal conversion rate?

[Rader2146]

Approximately how much crushed/powdered crystals does it take to fill a 10ml bottle for mixing?

I'm about to purchase a 1/2oz and was wondering if it is going to be enough to fill the bottle.

Thanks

I posted a reply but it didn't show up, so here goes again.
..... I used 6 grams of crushed crystals with PG in a 15 ml vial. 6 grams is .212 oz, so you definitely have enough crystals. The mixture I made is enough for me to add 5% to a recipe and wind up with a VERY heavy menthol juice. I am totally addicted to menthol, so that might give you a clue about the menthol mixture.

Perfect. Thank you.

I use a graduated cylinder, pour in 5ml PGA, drop in about 3-4 grams of menthol crystals until the graduated cylinder is up to about 7ml, and pour it into a vial. Stuff is STRONG. 2 or 3 big drops (using a dropper) are good for a 10ml bottle if you're not looking for a very strong menthol. I once added too much and boy was it chilly

Wizard labs went out of stock right before I ordered, so I ended up with 2oz off of eBay. After Filling a 10ml bottle slightly more than half full and filling the rest with PG, I found that I should have enough menthol to last a couple YEARS!!!

At that mix I found my taste at 1 drop per 2ml ratio. Steeping was a must. A couple days smoothed it out.
