Boiling procedure

I did the boiling outside using a 10 meter electrical extension cord and I placed the cooking plate on a wooden TV rack I had carried outside. I wore a lab coat with apron with standard nitril washing-up gloves and a 3M half mask with 3M acid filter (nr. 60923 - multifilter). Skipping the stones made wonders and it quickly started boiling (set it on the highest temperature from the start). After 1,5 hours of boiling (concentration at about 70-80%) the more or less unnoticeable water damp developed into thick smoke (NOx gas). After around 2 hours of boiling the smoke was so thick I got really worried that my neighbours would notice it so I quickly cut the power. Even after turning it of it generated insane amounts of white smoke (NOx gas) for 20 more minutes. I then decided I had to do the rest during nighttime, not to attract any attention.

That night, I started the next boiling session with 3 boiling plates at around 21.30 since it got dark at 23.00 when the heavy smoke would begin to generate. I started with 1,8L of un-concentrated sulfuric acid in each of my 2 x 2L beakers and 600ml in my 1 x 1L beaker which was used on my "weaker" plate. I worked from 21.30 to 07.00 in the morning for three consecutive days before I finally was done. End note: I tried to extend the working day past 07.00 on day two which almost ended in disaster. At around 09.00 AM, I was about to put on my hazmat suit and 3M gas mask to start another boiling session when I noticed the neighbour just outside the house entrance. Had I not noticed this in time I would have to explain to him why I was wearing the protective gear, and that wouldn't end well... So if possible, even when on an isolated farm; do the boiling between 23.00-07.00 if possible. No use taking unnecessary risks. I spent 5-6 days on this process considering the fact that I had to combat false information, misconceptions and work out efficient procedures. If I had access to this guide before I started I would have been able to shorten down this process to 2 days.

Additional boiling tips:

a. Consider buying 5 or even 6 single cooking plates to reduce the boiling time drastically. Cutting the boiling time in two will drastically reduce your vulnerability to detection considering the fact that you are forced to work outdoors.

b. You will quickly learn your "progress" (purity level of sulfuric acid) by evaluating the thickness of the smoke and how many ML has been boiled away. If you start at 1,8L of 28% purity just boil it until it reaches 550ml or so to be sure you have 90%+.

c. Unless you are using identical cooking plates you will want to adjust the amount of ML per cooking plate so that you have maximum uptime and so that the concentration reaches 90% on all plates at the exact same time. You will learn this after the first session.

d. Let the acid stand for 30-40 minutes after you cut power to the plates by unplugging the electrical cord extender.

e. You can store 90-95% sulfuric acid in plastic bottles.

f. Concentrated sulfuric acid does not fume or evaporate.

g. You don't need to go overboard with protection. It will take 10-20 seconds for 90%+ sulfuric acid to burn through regular nitril gloves (medium thickness washing-up-gloves) and several seconds for it to burn through clothing. Just be rested and careful and you'll be fine. I got several drops on my gloves on several occasions and I just wiped it off with a napkin (napkin quickly turns black) before it could burn through. Avoid the "one-time-use" super thin gloves, even if its nitril. The most important things to wear are regular nitril gloves, an apron and some kind of full face visor. 3M masks are excellent since they prevent fogging on the visor.
