DIY Fossils with salt dough

DIY fossils

A super easy craft activity that my boys LOVED. All you need is a simple salt dough and either items found from nature or toy dinosuars (or both!)

Salt dough recipe

  • 2 cups plain flour
  • 1 cup salt
  • 1 tablespoon of oil
  • 3/4 cup hot water (or there abouts)
  • black food colouring

Mix flour and salt in a bowl. Then add the oil. Add about a teaspoon of black food colouring to the hot water water and slowly pour it into the mixture, stirring as you go. If dough becomes too wet add a little more flour, or too dry add more water at a tablespoon a time. Kneed until it is a nice smooth dough.DSCF1216Divide dough into roughly equal sized parts and roll each piece to about 1 cm thick. let your childs imagination take over, as they choose which fossils to make. We went on a ‘nature walk’ to select shells, leaves, and things such as seed pods, and also used a selection of plastic dinosaurs.

I didn’t manage to get many photos as S needed a bit of help during the process, but I think its easy enough to work out what to do!

Bake them in the oven at 120 c (I used fan mode) for 1-2 hours, I greased the baking tray lightly with spray oil first, and turned the ‘fossils’ every half hour until they felt hollow and seemed thoroughly dried out. It depends on the thickness of your dough. You may need to remove some sooner then others before they get brown.DSCF1226DIY salt dough fossilsVarnish if you like, but we left ours as they were. S took his proudly to his Montessori pre-school where they have placed them in a basket with a magnifying glass for the other children to explore, so we have since made another batch and he seemed to enjoy it even more. x
