- The best results will be realized by pouring the soap into the mold at a light to medium trace. This will allow the soap to self level and avoid hills and valleys where the layers meet.
- Pour slowly into the mold to avoid splashes on the side of the mold.
- Wait 1 to 1.5 hours minimum between pouring your soap layers.
- When pouring the second and each additional layer, pour over a spatula held just above the level of the earlier pours. This will prevent holes in the surface of the earlier layers.
- Cover the soap between pours, and after the final pour, cover with freezer paper, cardboard, and a towel to insulate.
- Allow the soap to sit for 24 hours after the last layer has been poured. Unmold and cut your bars and set out to cure for a minimum of three weeks before use, rotating to expose each side of the soap.
Try making a soap with different colours and fragrances in each layer to achieve results such as a layered Neapolitan ice cream (strawberry, vanilla, and chocolate), or the red, white, and blue of the American flag.
Give your imagination free rein and enjoy.
