SWIM has some questions:
1)
In final stage why freezing naphtha? I just let all naphtha evaporate is this wrong and why. I presume freezing is only to make crystals, and is just optional procedure am I correct?
2) Can spice be dissolved in acetone and put on piece of cotton, let acetone dry and put inside vaporizer.
3) I can not find exact information, boiling point of spice at atmospheric pressure.
