You can do whatever you want with your own tobaccos. Us Mason jar folks are the ones not being experimental, so we won't dampen your creative spirits.
Me, I'll not be using store brand pickle jars. I don't even use jars that I've made my own pickles in for tobaccos. But, you can do whatever you want. There was even a guy on here a year or so back from some second or third world country that didn't have glass jars, so he asked about taping two metal bowls together to age tobaccos. Heck, if someone wants to burry them in an old shoe box, go for it. Let us know how it works for you.
