I am new to DIY liquids and I need some help. If I wanted to add Ethyl Maltol found here http://www.ecigexpress.com/diy-supplies-powders-and-crystals-c-43_92/ethyl-maltol-select-size-p-295 then do I need to do anything to it before I add it to my juice. The page I linked at ecigexpress says that I should microwave it. Adding the step of the microwave seems like it is starting to get a little complicated than I would like. Do I have to do this or does anyone just add it to your juice as is? Also, how much would I add?
