i have used this. it melts shatter. i put some durban poison wax into a .2 sub ohm vape and took a few puffs. ended up not sleeping for 2 days
ej mix definitely imparts a taste. there is a way to use half, however
i strongly recommend using half to minimize the taste distraction
to use half the amount of ej mix, hot water bath the wax double boiler style. the trick is to warm the wax so it naturally melts in and then add the ejmix. then stir constantly while the mild heat is applied until blended (up to 10 minutes, this is normal)
you are likely going to want to thin it out a bit and dilute the taste further. to do this, get some food grade propylene glycol (PG), and add about the same amount of drops as ejmix while still in the double boiler
ejmix is made with peg300&400 and pg. Polyethylene glycol, PEG was originally used in nicotine vapes, but its flavor was fairly overwhelming, so now people use PG or VG (vegetable glycerin).
the peg 300 and 400 is molecular weight, and that molecular weight is needed to dissolve the wax, but PG blends well with the ejmix/wax solution and is virtually tasteless by itself. the ejmix, not so much, so the PG helps dilute it slightly, but not completely
a word about VG: dont use it. not even a little. i failed to wash my tank out from some nicotine VG and it starting pulling the wax out of the solution. NOT what i wanted to happen at all.
Also, as strong as a sub ohm tank is (i couldnt even complete sentences puffing on martian candy wax through the .2 ohm tank), the fatal flaw, and it happened every single time, is that it eventually leaks through the filter and out of the tank, not only losing the good stuff, but making a TERRIBLE mess
