Rectangle Silicone Soap Mold + Bath Bomb Mold: A Starter Combo for DIY Makers

Azlok's Rectangle Soap Shape Silicone Mold (6 cavity) with an aluminium bath bomb mold is a two-in-one kit for people who want to make their own soaps and bath bombs at home. The flexible silicone mold releases neat rectangular bars, while the metal sphere mold presses round bath bombs. At ₹279 for the combo, it's an easy way to start without buying two separate tools.

What you can make with this combo

The soap mold has six rectangular cavities, so you can pour a full batch in one go. The 2-inch aluminium mold shapes classic round bath bombs. Between them, the pair covers most beginner and small-batch projects:

Cold process and melt-and-pour soap bars in a standard rectangular shape
Fizzy bath bombs using baking soda and citric acid
Sugar and salt scrub bars held together with a solid butter or oil
Lotion bars, wax melts and small candles in the silicone cavities
Shampoo bars for a plastic-free bathroom shelf

How to use the silicone soap mold

Silicone is popular because it flexes, so you rarely need to grease it. Once the soap has set, you simply push the base and the bar pops out with clean edges.

Prepare your soap base — melt-and-pour is the simplest for beginners, or use a cold-process recipe if you are comfortable handling lye.
Stir in your colour, fragrance or essential oil once the base has cooled slightly.
Pour evenly into the six cavities. Tap the mold gently on the table to release trapped air bubbles.
Let melt-and-pour set for a few hours at room temperature. Cold-process soap needs to cure for several weeks before use.
Flex the mold and turn out the bars.

How to use the aluminium bath bomb mold

The two-piece 2-inch sphere gives you a round bomb when you pack both halves.

Mix your dry ingredients (baking soda, citric acid, cornflour) and add a light mist of witch hazel or a few drops of oil so the mixture just holds together.
Overfill both halves of the mold so the mixture mounds up.
Press the two halves together firmly, then gently twist and lift off one side.
Ease the bomb out onto a soft cloth and let it dry for a day before wrapping.

Tips and safety notes

If you make cold-process soap, always wear gloves and eye protection when handling lye, and work in a well-ventilated space. Keep children and pets away.
Do a patch test with any new essential oil or fragrance before using a finished bar on skin.
Add fragrance oils and essential oils within the recommended usage rates — more is not better and can irritate skin.
Bath bomb mixtures are sensitive to humidity. On a damp day, the mix may fizz early; work quickly and store finished bombs in an airtight container.
These molds are for DIY body-care and craft use. Do not eat anything made in them.

Buying and storage tips

The soap mold measures roughly 19 x 20 x 2.5 cm and weighs about 80–90 gm, so it's light and easy to store. The combo is available in 1, 2, 5 and 10 pack options — handy if you run a small home business or make gifts in bulk. Do note that Azlok delivers any available colour if your chosen shade is out of stock; the colour of the silicone does not affect how the mold performs.

To keep both molds in good shape, wash them with mild soap and warm water after each use and dry them fully before storing. Dry the aluminium mold thoroughly to avoid water spots, and keep the silicone mold flat or loosely rolled so it doesn't hold a bent shape.

FAQ

Do I need to grease the silicone mold before pouring soap?

Usually not. Silicone is naturally non-stick, so melt-and-pour and cold-process bars release easily once set. A very light coat of oil can help with sticky recipes.

How many soaps can I make at once?

The mold has six rectangular cavities, so you get six bars per batch. Scale your recipe to fill all six evenly.

Can the aluminium mold go in the dishwasher?

It's best to hand-wash the aluminium bath bomb mold and dry it right away. This prevents water spots and keeps the two halves fitting neatly together.

Is this combo suitable for complete beginners?

Yes. Melt-and-pour soap and simple baking-soda bath bombs are beginner-friendly. If you move on to cold-process soap, take time to learn safe lye handling first.

Can I use the silicone mold for candles or wax melts?

You can. The rectangular cavities work well for small candles, wax melts and lotion bars, as long as you let the wax cool fully before removing it.
