Keep the water in the double boiler boiling for 3 hours.  Make sure that your pot is covered, the idea is to get it as hot as possible.  After about 2 hours it will start to turn translucent, if not keep cooking it at a very fast boil until it does. Cook for 1 hour after the translucent stage.  I have cooked it for about 4 hours once, and it made a beautiful clear batch of soap.  I have never tested my liquid soap with phenolthalein so I don't know how well that works.   

Dilution:
Scrape  the paste into a pot of 4820 ml of water for dilution. Break it up a bit to get it into manageable sized chunks.

Slowly  heat up your water/soap mixture to a medium heat and then turn it off overnight. 

Make sure the pot  is covered. If your soap is high in soft oils (which this recipe is) it will get a skin on it if it isn't covered.  Once you add the borax it will fix this but until that time, keep the lid on all of the time.   

If you have lots of coconut in your soap it will completely melt overnight.  If it is high in soft oils (again which this recipe is) you will have to reheat it in the morning to get rid of the last of the chunks.  In the morning heat up your mixture to just warm and melt any leftover chunks, again making sure you keep the lid on until it warms up.

The soap doesn't have to be very hot.  Add your neutralizer, I use borax
Neutralizer:
56 g borax
112 g water
Heat up the water and borax mixture in the microwave until the borax completely melts.  This is harder than it sounds.  Borax will not melt until it is very hot and it will become solid again as soon as it cools so you have to heat it up just before you add it to your soap.  When the borax is melted it will be as clear as water. 

When you add your fragrance to the soap it may cloud the soap., the soap will clear again as it cools. 

Sulfated castor:
This recipe should give you a very clear gel like liquid soap, but to get it totally clear you have to make a soap that is at 0% superfat. You are a soapmaker so you know that soap made with no superfatting will leave your skin quite dry. The only thing that will superfat this soap and not make it opaque is Sulfated castor oil. It is kind of hard to get, and really if you don't care if your soap is transparent, you can use any oil that you like. I like the clear soap so I hunted down the Sulfated castor.  [See understanding liquid soapmaking for an update about superfatting]
-add 70g of sulfated if you are using it, and fragrance. If you get the mixture too hot, you may want to wait for the solution to cool down a bit to add the fragrance, otherwise it will vaporize. Let it cool and voila, liquid soap.
It seems complicated at first, but once you do it a few times it becomes much clearer. Remember what CP seemed like when we first started.
