Ok guys so i have been doing alot more reading....i think i am going to follow cybs salt tek....however i have a question about the freezing step.....say you could get thing ALOT colder than a freezer (i am talking about liquid nitrogen wich i think is about -320 or something like that) i have access to a pritty much unlimited supply of the stuff...i use it for work. so basicly i am wondering if using this to freeze would either make a better product or possibly get things done even quicker? any one try anything like this or maybe dry ice i am not sure if it would help or hurt....shit for all i know it will freeze everything too much ruining it what do you guys think?

ok guys sorry i forgot to mention.....i am not talking about pouring a gallong of liquid nitrogen into the mix....i was thinking more of a couple drops wich wouldnt even have time to enter the mix it would instantly eveap as it hits the surface that would cool it intially but what i was hinking was take this cooled solution in a tray put it into a styrofoam cooler with multiple cups of liquid nitrogen inside essentially as the L.N. evaps in the cooler it would basicly turn this cooler into a super freezer.....i couldnt just bathe the trays in L.N. cause it would shatter the trays.....just figured i should make this point so i dont get "dont pour l.n. into the tray" wich i wasnt planning on doing anyway....this method would be colder than a freezer but it wouldnt be -300 in the cooler....if it was the L.N would stop evaping

Slow cooling is better for crystal formation. A domestic freezer (-18°C or colder) - sometimes preceded by refrigeration - has worked for thousands of people so you don't need to reinvent the wheel here.

A styrofoam cooler containing cups of liquid nitrogen would be constantly venting asphyxiant gas so you'd better not use it in a confined space.

The slower the cool down the bigger the crystals correct?

In the past I’ve just done the freezer method or used pentane and distilled the pentane with alkaloids to a small amount and evaporated that. Pentane is to expensive to let a lot evaporate.
