Mar hit it right on the nail head. Simply mix up your lye/liquid and your oils and use both at room temp without heating.
You can even mix your lye/liquid up several days in advance.
It's a pretty awesome technique, and I highly suggest you give it a whirl. Paul was the one who got me started on it and now i'm hooked !!! That's the only way I'll make soap.
It makes it much faster since you don't have to worry about oils cooling.
I also make my lye/liquid with aloe juice for an extra boost. Aloe juice can be found at wal-mart for about $7.50 a gallon. It's in the laxative section.
But when I make it I put it in a BALL plastic freezer jar. You don't ever want to use glass for mixing your lye/liquid into. Yes even pyrex has been known to shatter from the extreme heat. It may not happen the first time, but with repetitive applications it will weaken the glass structure. I like using the ball jars because they are a heavy duty plastic and can take the heat. (I use the 16 ounce size) And they have a screw on lid. So after I screw on the lid I wrap it with electrical tape because I also have little ones. Then I put them into a plastic box and put it on top of the fridge. Out of the way of little hands.
The ball jars can be found at wal-mart and other similar type stores, and even grocery stores may have them. And they are not expensive either.
Then I mark my batches by writing on a piece of paper and taping it to the lid to keep track of what is what.
Good Luck and if you have more questions PLEASE DO ASK !!!!
