Batch one- bars

My bars stayed in the tubes for 24 hours. I then put them in the freezer overnight. I must say I'm pretty proud of my bars. They are not perfect but I made them! They have small specks in them. I think they are air bubbles and not lye. I read that mixing at high speeds can cause this. I had my mixer on level 8 for about 15 minutes before I read that part, oops. Now to find someplace to cure them. I'm making another batch tonight.
