Oven-hardening modelling clay is great for creative arts and crafts projects. For our magnets, we used a self-hardening modelling clay that can be shaped like putty and then hardened in the oven at around 130 degrees. Modelling clay magnets are easy to make and are therefore ideal for craft projects with children. But oven-hardening modelling clay also offers many opportunities for advanced crafting enthusiasts to get creative. In this tutorial, you can learn how you can make such fridge magnets yourself.

Materials needed for making modelling clay magnets

  • Oven-hardening modelling clay in the desired colours
  • Biscuit cutters (heart, flower, star, etc.)
  • Neodymium disc magnets or ferrite disc magnets of suitable size
  • Strong adhesive, such as UHU MAX REPAIR
  • Rolling pin
  • Clean and smooth work surface
  • Baking tray with parchment paper
  • Glitter or acrylic paint

Making modelling clay magnets with the children

  1. Roll the oven-hardening modelling clay out to a thickness of approx. 3–5 mm. If the putty sticks to the surface, you can also roll it out between two pieces of parchment paper. Our tip: To make the modelling clay more pliable, we recommend kneading it with clean hands for a few minutes beforehand.
  2. Have your kids cut out the desired shapes from the rolled out clay.
  3. If your children want to decorate the shapes with glitter, put a little glitter on a piece of paper. Now your kids can dip the shapes into the glitter. To ensure the glitter sticks well, you should press it slightly onto the modelling clay.
Let the modelling clay shapes harden in the oven according to the instructions on the packaging. Once the shapes have cooled, the children can paint them however they like.

Please note: Don’t glue the disc magnets onto the shapes before baking as the magnets are not able to withstand the heat in the oven and will be demagnetised as a result. If you want, you can bake the modelling clay at only 100 degrees, but you should expect a magnetic force loss of approx. 20%.
After drying, use magnet adhesive to glue magnets of the right size to the back of the shapes. Then let the finished decorative magnets made of oven-hardening modelling clay dry for at least six hours. Make sure that you let the magnets dry straight and with sufficient distance between them so that they don’t attract each other. Until the glue becomes hard or viscous, the magnets can still easily slip out of position.

3D magnets made of modelling clay

Oven-hardening modelling clay is also perfect for making three-dimensional shapes that look especially great on the fridge and are a trendy gift idea. We made such decorative magnets and were thrilled with the results. However, when crafting, keep in mind that you still have to glue a sufficiently strong disc magnet onto your creations. So make sure your modelling clay shapes aren’t too small.

Modelling clay gift ideas

Magnets made of oven-hardening modelling clay are a wonderful gift to give to family and friends for Christmas or birthdays. There are no limits to your creativity. Each modelling clay magnet will turn into an eye-catching feature, be it as a colourful fridge magnet, on metal shelves, magnetic boards or magnetic walls. Moreover, each decorative magnet is one of a kind!
The magnetic shapes made of oven-hardening modelling clay look particularly great when paired with a magnetic noticeboard. You can find out how to make such a canvas in the customer project Magnetic Canvas. Don’t skimp on the dimensions of the magnets you are planning to use on the magnetic canvas because they have to adhere to the magnetic paint through the coat of paint and the canvas.

Disclaimer: The idea for this project came from the Göhner family in Regensdorf, Switzerland and was sent to us in 2008. This marvellous application has now been updated by the supermagnete team and new photos were added too. Thank you for a terrific magnet project!
