We all have our preference and what we recommend to someone making their first batch, I always recommend no color, no FO and at least a 2# batch. I think that you are able to see tracing better that way and there is less room for error... but that is just me. If you choose to use a FO make sure that it is safe for CP and does not accelerate or you will have soap on a stick. OMH seem to be fine... avoid florals. Also, use room temp. lye. Mix your lye several hours before you soap or even the night before. That, to me, is one of the most important things to ensure a good batch. You will get a lot of conflicting information.. it is because every one has an opinion on what they prefer and how they do it. Okay. Let's address this one at a time. Zap-means that there is lye left in your soap. Or in other words your soap is lye heavy. If you get a zap with your tongue (it is similar to the 9V battery on your tongue) it is not safe to use. pH strips are sold on-line through several different soap websites and also at some health food stores. You basically lather the bar and put the soap lather on the strip. It will tell you what your pH is. I think most homemade soaps will be between 8-10. IMO- you should be fully informed but if you know the basics and the safety measures, just make soap!! You will always learn new tricks and ideas even when you have been at it for a long time. HTH.
