Step-by-Step Guide:

1. Lay out a plastic sheet or old newspapers to protect the work surface. Make sure the silicone mould is clean and all materials are within reach.

2. Cut the soap base into small, even pieces to dissolve evenly. Place them in a microwave-safe container or use a saucepan in a double boiler to melt them. Gradually heat the soap base at short intervals to prevent overheating. Mix between intervals. If you have a soap thermometer, aim for a temperature of around 50°C.  This will help prevent the soap from getting too hot and developing air bubbles.

3. Once the soap base is completely dissolved, add the fragrance. The amount of fragrance oil can vary, but it is generally recommended to add about 0.5-1.5% of the total weight of the soap base.

4. Divide the melted soap base into separate containers for each colour. The number of containers should match the number of colours you want to use. Add soap dyes to each container to achieve the desired colours. Mix well until the colour is evenly distributed.

5. Carefully pour the coloured soap into the silicone mould. You can create multi-colored layers or solid soap, depending on your preference.

6. Lightly tap the mould on the work surface to release any trapped air bubbles. Spray rubbing alcohol (if you have any) onto the surface of the soap to get rid of bubbles and create a smooth finish.

7. Allow the soap to cool and harden. It may take a few hours, but it’s best to leave it undisturbed until it’s completely solid. Carefully pull the soap out of the silicone mould once it has fully hardened. Use a knife to cut the large bar into smaller, more useable pieces of soap.
