Square silicone soap mold – 4 cavities for glycerin soap, layered soap & DIY soaps multi-cavity soap casting mold (Copy)

Make square soaps yourself – silicone mould with four cavities

Clean shapes, soft curves and plenty of room for your design ideas: with this square silicone soap mould, you can cast four individual soap bars with rounded corners. The smooth surfaces show off marbling, colour layers and shimmering effects particularly beautifully.

Whether simple in creamy white, with subtle swirls of colour like in the example shown, or with bold contrasts – this silicone soap mould with 4 cavities suits many creative ideas. Create a coordinated soap collection or combine different colours and fragrances for a personal gift set.

The individual cavities already give each soap bar its shape. Once fully hardened, simply remove the soaps carefully from the flexible silicone – no cutting is required.

Ideal for glycerine soap, marbling and layered soaps

The square soap mould is ideal for creative projects using glycerine soap and ready-made melt-and-pour soap base. Its square shape creates compact soap bars with a simple, timeless look.

Particularly attractive design options include:

• Marbled soaps with delicate swirls of colour and individual patterns

• Multicoloured layered soaps with straight or intentionally irregular transitions

• White and pastel-coloured glycerine soaps for a subtle design

• Transparent soaps with shimmering colour accents

• Honey soaps and scented soaps for self-assembled gift sets

• Single-colour soap bars where shape and colour take centre stage

The four separate cavities are practical if you want to try out different colour and fragrance combinations. This allows you to create different soaps using the same mould.

Suitable combinations from our range

🤍 White and transparent soap layers

Combine our white melt-and-pour soap base with the transparent Super Clear glycerine soap base. Alternating between opaque and translucent areas adds variety to your layered soaps. With selected soap colourants, you can highlight individual layers even further.

☕ Creamy cappuccino look

For soaps in cream and brown shades, our soap base with organic shea butter pairs perfectly with the pigment Pure Rock Pearls™ Chestnut Brown. Complemented by the Cappuccino fragrance oil creates a harmonious design concept for coffee lovers.

🍯 Honey shades with a golden shimmer

Our glycerin soap base with organic honey is ideal for warm, honey-coloured soap bars. The Milk & Honey fragrance oil complements this look with a creamy, sweet scent note. For shimmering accents, you can use the effect pigment EcoSparks™ Allure Gold.

💜 Lilac-coloured soaps with lavender fragrance

White soap base and our Ultramarine Violet pigment create delicate to more intense violet shades depending on the dosage. The Lavender Extra fragrance oil is a perfect match. Lilac-coloured sections in a white base are especially decorative.

How to use the silicone soap mould

1. Place the mould on a flat, stable surface.

2. Cut your soap base into small pieces and melt it according to the manufacturer's instructions.

3. Mix in soap colour, pigment and fragrance oil according to the respective product instructions.

4. Slowly pour the prepared soap mixture into the four cavities. For multicoloured soaps, prepare separate colour portions.

5. Allow the soaps to cool completely and harden. Then gently loosen the edges and press the soap bars out from below.

Design tip: The wide, smooth surface is particularly suitable for marbling. With a light base and a small amount of contrasting soap colour, you can create an individual design for each bar.
