Now that you have a clue as to why this happened, I have one other recommendation (well, more than one.)
Learn to make soap WITHOUT the perfume (re: your other thread). If you don't have any soap-appropriate fragrances, make soap without ANY added fragrance. Sure in the other thread, I did say if you want to try them, to try them, but I should have first said, 'learn to make soap first' before experimenting with adding non-soap appropriate ingredients.
Even if you don't find your candy thermometer, you don't need a thermometer to know if the lye solution is cool enough. As long as you make your lye solution ahead of time (a couple of hours is good) and let it cool (covered) to room temperature or to a temp that feels comfortable to the touch (wearing gloves & touching the OUTER SURFACE of the vessel), it should be fine, as long as it feels somewhat close in temperature to your room temperature oils.
When melting your oils, don't use too much heat. If using a stove top, use a very low setting and remove from the heat as soon as the oils are almost completely melted (the melting will continue after you remove it from the heat, as the oils holds the heat). If using a microwave, use VERY SHORT bursts of time in the oven, like 15 seconds at a time; remove it and check it; start again; check again. You do not have to melt completely in the microwave oven either; almost completely melted is fine. Stirring partially melted oils, especially the very softish hard oils like CO and lard, they will finish melting by simply stirring the already warm oils.
Try to hand-stir WITHOUT turning on the stick blender a lot more than with the SBer running. New soapmakers have a tendency to over-use the stick blender and turn soap to mush before they know it. If you think it's not enough, it probably is already too much stick blending, so RESIST the urge to give it one more pulse. Incidentally a pulse is like 1 or 2 seconds.
So back to temperatures: wear gloves. Touch the outside of the vessels and compare how warm they feel. If the oils are clear (see through to the bottom of the vessel) and the vessel feels comfortably warmish to the palms of your hands, but NOT hot, it's good. If you the lye solution feels close in touch temperature, then you should be good to mix them together. Do this slowly and carefully, limiting your impulse to pulse the SBer again & again. A couple of times, 3 at the most, and you should do the rest of it stirring by hand. In fact, if you can't resist the urge to squeeze the button, just put the SB aside and use a spoon for awhile. Look for light trace by lifting the spoon out and dribble soap batter on top. If the batter leaves a trace or line along your dribble line at first, you are at trace. It may smooth back out and that's fine. Trace speeds up with more heat. Stick Blending accelerates the chemical reaction that creates heat. So unless you want Ploppy soap, just stir without stick blending.
This is a good time to separate the soap out for adding colorants. Hand stir in the colorants also. You may want to SB the colorants, but if you do remember 1 or 2 seconds at the very most, then hand stir. Some colorants make the batter thicker, so take notice if one of them does, and get ready to pour your soap sooner. (Titanium dioxide does, and I have noticed some greens do as well, but the ones I have that thicken soap also have TD in the ingredient listing for those greens.)
You mentioned some liquid colorants. Where did you get those? Are they the kind from a craft store that sells only Melt & Pour soap? If so, then they are likely only for MP, even though it never seems to say that on the package, and will probably fade in soap (I've done it myself when new.) If they are food coloring, same thing, some will stick in CP & HP soap, but fade and some just totally disappears. Some stains your fingers, though, so we advise against food coloring in soap.
