Simple Steps on How to dye seashells for Summer Crafts with Kids

We love taking a trip to the beach and after arriving home and finding a pocket full of shells again we decided to use them in some crafts instead of just adding them to our nature table. This simple tutorial walk you throw how to dye seashells so that you have a pretty material to use for summer crafts. It was so easy we did it with our preschooler and at the same time she learnt a little about mixing colours and science but mainly we made pretty pastel seashells for our crafts this year.

How to dye Seashells

using food colouring to dye shells from the beach

A search for how to dye sea shells brought up this post about it from The Educators’ Spin On It using Easter Egg Dyeing Kits, which we don’t have in the UK but with knowledge of seashells being made from calcium and chemical reactions with acids I put together some vinegar and water mix which would react slightly with the shells but not erode them completely and allow the food colouring to be absorbed into the shells.

With 7 small glass bowls we mixed in some water and vinegar (around a 1:4 mix is what worked the best) and added black food dye to one bowl then in 3 other bowls added the 3 primary colours – a red, a blue and a yellow. They were easiest to stir with a toothpick.

The 3 primary colours were quickly identified and then we moved onto colour mixing to discover new colours – pouring in a tiny amount of each colour T mixed them together – as they blended we took time to discuss the 3 colours (with slow stirring with the toothpick we were able to see all 3 colours at once).

With all of the colours made – black, red, blue, yellow, orange, green and purple we then added 6 shells to each pot and T stirred them in the mixes with a tooth pick.

Leaving the shells in the bowls for 10 minutes whilst we went off and cleaned up a bit (dyeing shells gets quite messy especially when using food colourings). We then removed them and laid them out on a paper towel to dry.

The shells have produced a really pretty pastel effect on them – we also tried dyeing with the same method we used for the egg shells and the red produced a deep colour but all of the other colours we still pastel coloured.

  1. Thank you!! The shells looked beautiful. We are on a waste reducing journey so along with a pretty basket to put them in from the local second hand shop, this was a beautiful zero waste gift for our Niece. We also made her a scroll card by doing a burnt edges letter in a bottle. Cute as. Thank you!
