Okay so in my country naphtha is quite hard to come across, so I've bought hexane. I've found caustic soda (lye) in the supermarket. MHRB literally grows on tree over here

. I can't use any heating element atm and I'm very limited on the freezing element (I'll try to avoid it).
What TEK would you recommend me do? and will it work well with the hexane?
Thank you all for your inputs.
Hello, Is there anybody in there? Just nod if you can hear me.
