thats a really bad tek writeup. the guy is using zippo fluid...

can you tell us step by step what you did in your own words. also how much NaOH did you use? the pKa is important, you cant just bring the ph down.

I thought that was a good tek. I pretty much followed his steps exactly. The only part I was confused about was with the lye. He says to get 100ml of water and add as much lye as you can until it doesn't dissolve any more. I added 150grams and it was still dissolving. I then added that to the 400ml of liquid and added a bit more lye.

I'm gunna try the Lextek this time, which has the extra de-fatting step so hopefully that will give purer results.
