Hi how are ya
It seems you have your head around the concept of reducing ephedrine/pseudo-ephedrine to methamphetamine, thats a great start. Some people here will try a reaction (with almost no understanding), fail a few times, and
then learn how to do it properly!
1gm is possible; someones first few cooks may only yield 20% or 30%, and as experience and practice is gained, yields may increase to 60 70 (even 80%). So if you work with a larger amount of epehdrine (maybe 3gms or 5gms) you may have more success.
Its kinda like when you learn to butter a piece of toast, if the toast is 1" x 1" square then it will be difficult to paractice on.
But yeah if its bigger then it will be easier to work with.
If you want to use 30% hypo then you probably will need to reflux for a long time (like 12 or even 24hrs). Geezmeister and others would be the guys to help you with this one.
Vapour Containment Unit - Its just to stop the smell. I think a balloon on top of the condenser should be ok for this... anyone else pull me up if this is not good (I know its ok with RP but I'm not sure if there's a difference with a hypo rxn). You wont need a face mask.
Recrystalisation is not neccessary, and on such a small amount you may find out you are left with almost nothing. After adding the HCl to the sep funnel and shaking, let a bit of the water out into a plactic cap or something, so you can test the pH. If it is still higher than 7, pour it back in to the sep, add a bit more acid, and shake again. REMEMBER - 1 drop of acid may change pH13 to ph12, but the same amount can change pH7.5 to something like pH4.5. The closer you get, the more sensitive it gets. If you're at pH8 or something you may want to add diluted acid; half acid and half water, so you dont over do it. When its ph7, drain the water/meth out on to your pyrex dish, and slowly evaporate the water to leave your meth behind, dont let the water boil.
A safety fan is just a fan that is aimed down on the evaporation dish to blow the fumes out of the way. When you are evaporating in alcohol, the fumes can be ignited by the flame heat source. The fan will just blow the fumes away so they dont linger and catch on fire. However, at the end of your cook, you will be evaporating in water so this wont be nedded.
