I'm of the opinion that there aren't no failures in soap making, only opportunities to learn more.
Opportunity to Learn More:
1) QUIT MAKING LARGE BATCHES! Get yourself a 4" Silicone Square Mold; most soap suppliers sell then for under $20 and you can even get them on Amazon. It has a total batch weight of 20 oz, which with a 33% Lye Concentration and NO scent will use 14 oz of oils. and yield 4-5oz bars of soap.
2) Get yourself a decent soap recipe because quite frankly, the one you have right now sucks. BrambleBerry has a fairly easy
Simple and Gentle Soap that is just three ingredients to start with (Olive, Palm and Coconut Oils). In SoapCalc, start with 14 oz of Oils (because you are going to buy a 4" Silicone Square Mold), 33% Lye Concentration, leave the SuperFat at 5% and then enter the ingredients as percentages (from the website) and then follow the instructions. And since you already have some Castor Oil, I'd add that at 5% and drop the Coconut Oil to 20% and the Palm Oil to 31% to add some extra bubbles. Make sure you melt you melt your container of Palm Oil and stir BEFORE weighing out.
3) Make several [small] batches of PLAIN soap...no colorants, no scent. Yes, it will be hard...all those lovely scents, all those wonderful colorants...all that wasted money and frustration because you didn't take the time to learn the basics of soap making. Learn about emulsion, learn about trace (light [thin], medium and heavy [thick]. Learn to pulse your stick blender for just a few seconds and then stir to see the changes taking place in your batter. Learn how temperature affects your batter and what you like. Some folks soap at low temps, some at room temps, some at higher temps. FYI - Making a 'naked' bar of soap is NOT as easy as it sounds...I have two such bars on my desk; one from when I first started making soap and one from a year later...there is a difference.
4) Once you can make a consistent batch of PLAIN soap, now is time to add some color. Keep it simple...start with a SINGLE color soap; I had purchased a a couple of Mica Samplers. I added it a few different ways...dispersing it and then adding it to my batter, adding it straight into my oils, adding it straight into my batter. From my experiments with using colorants my preferences are to add straight to oils for single-color soaps, for multiple color soaps, I disperse in a bit of oil first. I always disperse oxides, pigments, clays, ultramarines in distilled water. The exception is Titanium Dioxide which is dispersed in oil. You will need to find what works FOR you.
5) Now it's time to add some scent. I'll be honest, I keep it fairly simple. I use my 4" Silicone Square Molds for testing and so when I'm testing new FOs I just dump in a Trial or 1 oz bottle. Nothing else because part of the testing is seeing how the FOs reacts with MY recipe under MY conditions...does it accelerate, does it rice, does it slow down trace, does it discolor and if it does, what is the level of discoloration because even FOs without vanillin/vanilla can discolor...usually a yellow shade.
NOTE: Now not FOs are going to react the same which is why it is important to test them BEFORE you start buying 8 oz bottles only to end up with 50 oz of solid concrete and have to toss a bowl because you destroyed it trying to chip out the soap, and boil the shaft of your stick blender and pray that it loosens said concrete and you don't have to buy another one. Two FOs that I would recommend for a beginning soap maker is Black Raspberry Vanilla and Oatmeal Milk and Honey.
Once you are comfortable with using colorants, now it's time to have some fun. One of the easiest "swirl" techniques is the ITP (in the pot swirl). There are tons of videos online that show you how it's done. Another "swirl" technique is the Drop Swirl. And both of these techniques can be just two-colors or they can be three or more colors...that is the fun of soap making.
6) Not every soap is going to come out the way you want it; the first six months I ran about 50/50...lots of 'opportunities to learn more'. Of course, I didn't know about SMF when I first started out...I was completely out in the wilderness, cold and afraid and lost and they took me in and warmed me by the fire and served me cups of coffee heavily laced with liquor (there was no liquor actually served). I had just had another massive failure and was so dishearten and frustrated. Mind you, I was still making 50 oz batches so I was wasting a lot of money (my failures couldn't be salvaged). I'm on my third year of soap making and I still screw up, but at least they are small because I bought a couple of 4" Square mold...to not only test new scents and colorants but to also test techniques (I also have a 6" Silicone Slab Mold).
Slow down, learn to crawl first.
