Have a friend that has a large supply of animal Fat and has made a batch of bio,
the problem is that there is a layer of white above the Glycerine
I have sugested that he might have produced some soap and that is usaly because of to much sodium hydroxide.
Has anybody else made bio from animal fat and is it the same rule of thumb that you start with 3.5 gram of lye per 1 ltr of new oil ????
When he did the tritation it only needed 1 ml of lye to turn pink !!!
If you could help I would be greatful and I will pass it on to my friend
