Glycerine Color

I've been using my Lye glycerine for weed killer, but I'm looking at trying my hand at making soap again.

I get about 2-3 gallons of gIycerine per batch of Bio. I cook (about 1 gal at a time) my gylcerine till it gets to 250-260deg. to meth. Sometime higher if I get distracted. When it cools, sometimes it is dark brown, sometimes it's a light tan.

Why the difference and which is better for making soap?

The colour is not that important, just the result of what base feedstock is. The recipe is the same, however depending on the feedstock it may or may not be necessary to use a binding agent, such as lard (pig fat).
If you are using NaOH and a hydrogenated oil or some other long chain oil you do not need the lard. just 30grNaOH and 200ml liquid along with the essential oil of your choice (I use 15ml per 4 L batch).

Give me the exact feedstock, and assuming it has been processed using NaOH and I can give you a specific on it.

I use vegetable oil from the local American Legion, We use it 3 or 4 times for cooking wings, fries, or fish. So far it has always trirated at 0.6.
