How to Make Ombre Bath Bombs

Sharing is caring!

Want to take your bath bombs to the next level? Here’s how to make ombre bath bombs.

I enjoy making bath bombs. I like knowing what goes into them and I love the smell of essential oils.

Previously a friend had asked me to make some Minecraft bath bombs to be used as a birthday party favour (isn’t that a great idea?). I took my regular bath bomb recipe and painted them.

Now the same good friend asked me to make Disney Frozen-themed bath bombs for another birthday party. Now there were a few options I found when I was looking for ideas online. There were cute snowflakes, but I don’t have a snowflake mould. But I did see some ombre bath bombs. They looked perfect.

What is Ombre?

Ombre is the French word for “shaded” and it is the transition of one particular colour, going from a tint (a light colour) to a shade (a dark colour).

So I decided to do an ombre version involving 3 tints or shades. Since teal is the colour of choice for Disney’s Frozen, I used that. I got some nice teal mica colour from Amazon.

How to Make Ombre Bath Bombs

I used the bath bomb recipe I always use. I added some nice Wild Orange essential oils to them as well.

Basically, you’re going to divide your mix into 3 parts and add your coloured mica powder in varying amounts.

Now since I was making about 20 bath bombs, I tripled the recipe – one batch in each bowl. To one bowl I added about 3 teaspoons of teal mica powder – this will be the darkest shade. To another bowl, I added 1.5 teaspoons of teal mica powder – this was my middle shade. The last bowl had only a half teaspoon of mica powder – this was my lightest tint.

There isn’t really an exact science to this. You can measure the amount of mica powder by how it looks. Obviously, more mica powder will result in a darker shade. Basically, you need light, medium and dark. I added the mica powder to the dry ingredients, before adding in the fractionated coconut oil, essential oils and spritzing with witch hazel.

If you are making just a regular batch, I would divide the dry ingredients into 3 bowls. You can just eyeball it. Then I would add the mica powder and then finish off with the fractionated coconut oil, essential oils and witch hazel.

The mixing process is exactly the same. You just have 3 bowls with various shades or tints of the same colour.

Assembling the Ombre Bath Bombs

Now you can do this in a variety of ways. You can either go from light to dark or I went light to dark and then back to light. I like the symmetry of the colours this way. It’s just how you layer the bath bomb mixture into the circular mould.

Starting with half a mould, fill a third to halfway of the lightest tint of the bath bomb mixture. Top with some of the medium shade. Then you’ll finish off with the darkest shade and you’ll do that smoosh thing to compact it into the mould. Then you’ll repeat the same process for the other half of the mould.

When you smoosh the 2 together and remove the mould, the result is an ombre bath bomb!

The great thing about this is that it does not have to be perfect, or consistent. In fact, it looks better that way. So varying amounts of the 3 tints or shades are fine. All you have to do is remember to keep to the order of going from the lightest tint to the darkest shade.

I found that one of the shades was being used up quickly while the lightest tint was being used less, so the next few just had more of the lightest tint. Just put more in.

You don’t even have to layer it in straight and even. In fact, I purposely layered them in at a bit of an angle for some. I like how those turned out.

The hardest part is waiting for them to dry overnight. In all honesty, I have nightmares about waking up in the morning only to find that they’ve all fallen apart! (They didn’t!).

The Finishing Touches

To complete the party favour, I made thank you cards using my Cricut and tied them with a matching ribbon. How cute is this?

I really love how these ombre bath bombs turned out. They’re so pretty! I know the birthday girl is going to love them.
