Can I add glycerin to a lotion bar?

It has been awhile since I made a lotion bar, but when I get the chance to make them I love using them right away.  Susan of Point of Interest recently had a question - Can I add glycerin to a lotion bar?  So she replied in a post answering that very question. If you like to make lotion bars and you had the same question, then read this posting and see how Susan answer that very question.
