Good Morning All, Last night I wanted to make just plain cinnamon euice. I used the e-juice calculator that can be found on here. There is actually no plain cinnamon recipie on it. Well anyway i made a 2.0 Ml batch at 15 % flavor and it told me to add 10 drops or 0.30 Ml. I followed the mix of PG VG and PG Nic exactly and accurately. I mixed it up put it in my clearomizer and it was WAAAYYYY too strong and it started melting my clearomizer tank. Obviously I cant follow the e-juice calculator when using Loran cinnamon oil. I emptied out my tank cleaned it out and remade the batch this time using only 2 drops of cinnamon oil for the 2.0 ML batch and it seems fine. My quesiton is are there any other oils that are strong like this and the juice calculator cant be used for the ratio? And is there a calculator out there for this cinnamon oil or other similar oils? Thanks in advance.
