If you’d like to do this on your own –
You will need:
Tagua Nuts (sanded if whole, slabs or beads).
1. Put your tagua nuts into a plastic or metal container with a lid. In a separate container, mix 4 tsp. of a fiber reactive dye with 1 cup of warm water. Mix thoroughly.
2. Pour the dye and water mixture over the nuts (not the other way around – this prevents splashing). Be sure the tagua nut is completely covered. If it’s not, make some more and fill the container until you can see the tagua nut is completely immersed. Replace the lid and allow the dye to penetrate for one hour.
3. After an hour, remove the lid and add 1 1/2 tsp. of soda ash and mix well. Let the soda ash penetrate the nuts for at least another hour. The soda ash acts as a fixative which will prevent the dye from running.
4. Rinse the tagua in cold water. Add 1 tablespoon of detergent and mix well with the tagua, then rinse them again in cold water.
