Rainbow Glitter Salt Dough

Here’s a simple recipe for rainbow glitter salt dough for making coloured models to harden and keep! There are so many ways to play with this extremely low-cost salt dough and it’s loved by older kids too.Recipe for rainbow glitter salt dough!

We are very passionate about playing with all sorts of doughs because of how cheap, quick and easy they are to make at home and because of the many educational and developmental benefits they provide for young children. Play dough is the one we make the most often, but salt dough comes in a close second as it can be made into models and keepsakes that last for years!  We have coloured our salt dough many times, but never made the whole rainbow to work with at once, so it was time to have a go! Rainbow marbled salt dough


Super simple recipe for rainbow salt dough:

2 cups plain flour (all purpose)

2 cups salt

1 cup warm water (add a little more if too dry but start with this amount)

Glitter in different colours

Gel food colouring in rainbow shades. We use these Wilton Gel Icing Colours in all our doughs as they’re so vibrant!


Mix the dry ingredients together in a large bowl, then stir in the warm water slowly. The mixture should be a little sticky, but as you continue to mix it thoroughly it will become like a regular dough. At this stage turn it out not a counter top and begin to knead it for a couple of minutes until it is soft, smooth and not at all sticky. As with all these recipes it’s possible to add too much or too little water, so just balance the other ingredients to adjust it if it foes wrong. Doughs are very forgiving!

Then separate the dough into 7 balls of equal size and push a dent into each one. Into the dents add a small amount of each of the gel colours, then fold the doughs over and over until the colours are mixed in (try to avoid touching the gel directly as it does stain for a few hours.) It takes a bit of work to get the colour completely through the dough but it’s worth it and great for those little hands too!

Then they simply broke pieces off and used them to create whatever they fancied. The lovely thing about this coloured dough is that even when mixed together they don’t look murky or turn to brown sludge like so often happens. Instead a lovely marbled or patchwork effect occurs and it’s so pretty!Rainbow marbled salt dough heart

They rolled and cut hearts, stars and other shapes to become magnets. pendants and little models. Remember to poke a hole through with a straw if you wish to hang or thread with your creations later.

Cakie made a rainbow kitten and together we made a rainbow by rolling long sausages of each colours and layering them up together.

Once they had finished their designs and eels we popped them on a baking tray and put them in the oven on very low heat to “air dry” them for 3 hours. Ours was turned to about 100 degrees C (approx 210 degrees F). If your models are thick they will definitely need to be turned over during the process and may even need a mother few hours in there. We try and keep ours just half an inch thick at most.

After hardening the colours fade a little and are not as vibrant, but by applying some PVA or clear glue (or a clay varnish if you can get your hands on some) then they can be revived and look shiny too!

    Amazing, simply amazing… We have made salt dough ornaments for years. Colors fade, brown when “air drying” in oven, etc you know the deal. These are absolutely stunning! I am so excited that I think you’ve found the greatest solution to the fading problem: the Gel Food Coloring! That has to be the key ingredient! Amazing. Thank you so much for sharing, I’m simply blown away by their color! We’ll be full of rainbows this week.

    Hi! I love this recipe! One quick clarification, do you add the different colors of glitter all at once when you first mix the dry ingredients?

  3. akira says

    hey, that is brilliant idea.. but can I know, after you air drying the dough, how long it can hold? I mean, do we have to keep it on refrigerator? or any container? or we can just keep it on room temperature after the air drying? because I want to paste it on our classroom’s wall

    Hi Anna,

    We love salt dough and have used a recipe similar to what you posted. Problem is that over time the dried dough cracked and broke. Any thoughts about how to stop this from happening?

    Wow – what great colors! We love to make play dough, such an easy recipe and the glitter makes it fantastic! Thanks for sharing.

    Can this recipe be shaped into desired objects and baked to hardened? If so, Please include temperature and length of baking time. Thank you so much!
