What do you guys think?

[green soap]

I got the 25% from this thread http://www.soapmakingforum.com/showthread.php?t=41669&highlight=glycerin

Where it says it makes up 25% of the finished soap, and you can calculate the exact amount of glycerin by calculating .7 grams of glycerin for every gram of lye.

25% of the molecules ARE glycerin. However, they are tiny, compared to the resulting soap molecules, so make up only about 10% of the final soap WEIGHT.
