Step one

Prepare the Avocado Natural Dye (Please follow recipe steps here:

Step two

Prepare the Carrageenan - Dye mix

    • Weigh out your carrageenan powder. You will have different results depending on whether you use carrageenan iota or kappa.
    • Add the 18 grams of carrageenan powder into the glass jar.
    • Measure out the prepared avocado natural dye to 450ml
    • Pour the cooled avocado natural dye into the jar.
    • Use a blunt knife or spoon to mix and scrape of any carrageenan lumps that may have stuck to the glass and that don’t have contact with the liquid (dye)
    • Place the glass jar lid on tightly and shake the mixture.
    • Leave for 12-24 hours

Step three


Once the mixture has had time to settle (the carrageenan absorbs the water in the dye), the mixture is ready to use.

Step four

Pour the mixture into the saucepan and turn the stove onto a medium heat. Use 50 ml of water to rinse out the jar and also pour this into the saucepan. Stir continuously for 5 minutes breaking any lumps apart.After 5 minutes, add the vegetable glycerol in. This is the plasticiser and gives the material it’s flexibility.

Step five

After another 5 minutes, or until the mixture has become very liquid, turn the stove onto a low heat.

Step six

Now prepare your mould on a flat, level surface, as close to the stove and saucepan as possible, as the mixture cools down very fast.

Step seven


When you are ready, turn the stove off and pour the liquid quickly and directly into the mould.
