Rebatch soap will have a grainy texture once cured. It will not be as smooth as a regular bar of soap. If you are using multiple scraps of soap, try to use the same fragrance, otherwise, you might end up with a not-so-nice fragrance. You can use different colors, but keep in mind that they may not always blend together to form a new color. Sometimes, they may appear as specks.
If you have a crock pot, you can use that instead. You can also melt the soap directly in a saucepan without the bowl, but make sure that it’s small so that the soap doesn’t scorch. [1] X Research source
If you want something extra-special, try tea or milk instead. You can also try goat’s milk or buttermilk. If you are using freshly-made cold process soap, you may not have to use as much liquid, if any at all. [3] X Research source
If you are using a crockpot, cover it with a lid and set it to high heat. You will still need to crack the lid open and stir it from time to time so that the soap does not burn. If you are heating the soap in a pot, heat it over low heat. [4] X Research source
At some point, the soap will no longer change texture. If some time has passed, and the soap still looks the same, it’s not going to melt any further.

You don’t need to use as much essential oil as fragrance oil. This is because essential oil is much more potent. Do not use candle making fragrance oil. It is not skin safe. Another option for fragrance is through spices. This will also give your soap some color. Plan on using 1 to 2 tablespoons (7. 5 to 15 grams) of spices, such as ground cinnamon. [9] X Research source
Another nourishing additive is honey. Not only will it make your soap smell nice and more moisturizing, but it will also give it a nice, golden color. Plan on using ¼ to ½ cup (90 to 175 grams) of honey. [10] X Research source
Soap making dye is very strong. Mix in 1 to 2 drops at a time until you get the color you want. You must use soap making dye. Do not substitute candle making dye, as it is not skin safe. Food coloring will not work either. You can add dye to brighten an existing color. For example, you can deepen a light blue soap base with blue dye.
¾ to 1 cup (90 to 120 grams) of exfoliants, such as oatmeal, almond meal, coffee grounds, etc. 1 cup (50 grams) of low volatile oil content herbs, such as chamomile, calendula, and lavender. They can be fresh or dried. 1 to 2 tablespoons (1 to 2 grams) of high volatile oil content herbs, such as rosemary. They can be fresh or dried.
You can purchase soap making molds and stamps online and in arts and crafts stores. Alternatively, you could use a silicone ice cube tray or baking mold.
If you are in a hurry, pop the soap into a freezer for 1 to 2 hours before de-molding it. [13] X Research source
Some types of rebatch soap (typically made from store-bought bases) only need to dry for 2 days.
