1. Mix water, lye and MHRB
2. Add warm naptha, swirl gently so as not to form an emulsion
3. Collect naptha and freeze precipe

Questions:
A) How mych lye and water is required for 120g MHRB?
B) After the freeze precipe & crystals collected, can the same naptha be reused to pull again?
C) How long should 1 wait for the lye to break down and base the MHRB?
D) How long should one freeze the naptha when doing the precipe?
E) Does it matter how much naptha is used? if yes how much should be used for a 120g MHRB extraction?
F) Is swam lighter fluid clean enough to use as naptha for this method?

Any answers will be much appreciated!

A) There are various teks and ratios people use, there is no real consensus. For 120g I'd use about 1.75 liters of water and 80-100g of lye
B) Yes, it can
C) Give it about 12-15 hours
D) 24-36 hours is a good time period
E) Yes, it makes a difference. If your freeze precipitating and not attempting to evap all of it, you could use 300-350 ml. Otherwise you would preferably use abour 150ml
F) If it says 100% naphtha it should be fine, Ace Hardware's VM&N Naphtha is the most commonly used so most would advise you to stick to that.

Thank you.

When freeze precipe is complete, its just a case of running the naptha through a coffee filter to collect the crystals, right?

Then the naptha can be transfered back to the lye/mhrb/water mix to pull again?

Use a coffee filter, but try not to decant all the naphtha. Your better off leaving just a little bit and evaporating it over a few hours imo than decanting all of it through a filter - try to leave the crystals in the pyrex dish with a little naphtha and let it evap. Use the decanted/filtered naphtha for the next pull.

ythan eh???
