Fair enough, DeeAnna. I, too, am far from an expert on Rosin and I'm sure my observations are, at best, anecdotal. I had read so much (CF's books and a few old-timey manuals), and was so sure that Rosin was going to do such great things for my liquid soap, that I bought 5 pounds of it in December of 2012; I still have 3 pounds of it. I can say it never lived up to my expectations.
My notes from that far back were lost, but looking back at my handwritten notes in Failor's books, I'm sure I've used upwards of 15% of my oils. It just never seemed to add anything to the soap. I found that 2% kept the lather where I wanted it and it allows me to (slowly) use up what I have. As a plus, I live in an area that practical eats up anything with balsam, fir, or pine in it--and if you can make a case for all three, even better!
Truthfully, I never thought it was worth monkeying around with in bars. Maybe the attributes the old-timers give it are best show-cased in bar form?
I've got some down time this week. Maybe it's time I try out the bars. Out of curiosity, how's the clarity of those you made?
