About exp potions

If each potion cost to make 1 orb.Once I have 5 potions done, I use one do i have to pay another orb for making another?

I mean each time i do a potion do i have to pay 1 orb or just with playing 5 orbs you can make as much as you want?

 

1 orb = 1 potion

What made you think that you can make a free exp potion?

 

We eat the glass from the potion? xD

 

Bottle itself provides more exp, thus it gets munched on the process. ^_^
