Is anyone on here using the no-titration 2 stage method? Across the pond, it use has led to few soaps produced, greater yield, less lye required and less meth.
The process involves using a 10/90 test after the first dose and glyc separation, which determines the number of litres left to dose. The remaining veg oil is accurately address (7 grams per litre - koh or 5 grams NaOh). Meth is down to 16% by volume overall divided into 80% first dose and 20% 2nd dose. First dose is done on the basis of 7 grams per litre with KOH and 5 grams NaOh - can't remember the amount for ASM.
I am using the no titration method shamelessly borrowed for the UK. I run approx. 80% of the methanol on the first run, and adjust for the second run based on 90/10 results. 2% ASM works for both the first and second runs in my system.
I still use around 20% methanol based on original oil volume. I do recover methanol from glycerin so I have not tried to reduce the methanol used.
The method works, but it is not standardized. To get the reductions in methanol requires some experimentation to tailor the method to your specific oil. The method also calls for Sodium Methylate (ASM), which is more difficult to obtain than either NaOH or KOH.
In my opinion, the reduction in methanol is mostly due to the use of sodium methylate and using two base stages. Giving up the titration in favor of adjusting the second stage recipe probably uses more methanol than titrating and using neutral's base/base method.
Again, in my opinion, not titrating is the main advantage of using the "no tit" method.

RickDaTech, I looked at the methods in your link and you recommend using 5g NAOH instead of the 3.5g in the instructions on the wiki. Is that what you mean by not standardized? Do you think that is the reason it dos not work for me? Richard did say 3.5g NAOH was not enough for the first stage and your instructions say to use 5g. I can not find anywhere in your instructions or the instructions on the wiki that say to use ASM. All it says is to use methanol.

Ive used no titration method several times and had good sucess with oil titrating under 4ml KOH, above that it becomes unreliable. So the problem as I see it is if your oil supply is not consistently below 4ml KOH you still have to titrate to make sure it is suitable for the method. It does save on KOH but its a small saving. It will produce less soap and that is a big advantage for those who use water washing or Heat and Settle to remove soap. I dry wash so it makes no difference to me.
