Don't throw it out. It's an easy save. Just throw it in a double boiler or crock and remelt it. Stir or SB, if you can, and then pour into the mold. It will be fine. You can even separate some of the melted soap out and color it and stir it back into the pot for a two-toned effect. Rebatch is too thick to actually swirl.
Don't be surprised if when you are stick blending the oils turn into a thin liquid. Just keep stick blending and it will thicken back up. I've had that happen a couple of times. It traced, I poured it into the mold, it separated, I took it out of the mold and poured it back into the pot and started stick blending to remix. It turned to thin liquid. I'm saying, "Kitten Love???" Kept blending and then it rethickened. turned out fine. Good luck.
