Wot heat source
drinksmokesleep Reviewed by drinksmokesleep on . quick question i found these sweet little jars in my basement that would be too perfect to make a vap out of. Perfect size, a big bigger than a light bulb. The only difference there would be is that this glass is thicker and wouldnt break as easily. Do you think that it will not work if the glass is too thick? or will i just have to hold the heat to it longer? thanks Rating: 5
