Lots of good info on this thread. I'm getting ready to open up my 55lb of lye from a local chemical company. A little nervous. I've used lye beads before and then went to flakes, which I love, but needed to make things cost effective. I wish I had saved more of the plastic bottles the flakes came in to store the new lye! I've come a long way in soap making from the days when I was buying 12 oz bottles of lye from Ace Hardware! Yikes!!
