With water, salt, flour and little more, we can make polymeric clays at home.

Polymer Clays

Polymeric clays are a type of clay highly recommended for all those people who like crafts.

It is a really moldable material that we can also make at home, so we are going to offer you below, a step guide in which we explain how to make polymer clays at home.

Polymer clays are a type of clay that is obtained through the mixture of various chemical compounds such as PVC particles, as well as softeners and coloured pigments, so that a mouldable mass is obtained that once dry is really resistant. This type of clay can be bought in craft shops but we can also make it at home, as we explained.


  • 1 cup flour
  • 1½ cup salt
  • 1 cup water (give or drink a little)

Steps for making polymer clays at home

  1. The first thing we're gonna do is mix the salt and flour in a bowl.
  2. Add water with ¼ cup at a time, mixing well. You may not need all the water or you may need a little more depending on the humidity and temperature in the work area.
  3. Mix until a ball forms, then take it out of the bowl and knead a little. It must be firm but flexible.
  4. You can pick up pieces and use dye to color them, or you can leave them and paint on them later.
  5. Now you have your clay to create what you want. Once you have finished working with it, you can let it air dry, or bake it at 250 ° F, although it will also depend on the thickness of the pieces. For something the size of a ping pong ball, you can bake at that temperature for about 20 minutes.
  6. Once the clay is dry, the pieces can be painted, varnished and even waxed to obtain a high gloss.

Steps to make salt-free polymeric clays

This recipe is a little more complicated as it does not use salt but produces a finer finish.


  • 2 cups corn starch
  • 2 cups baking soda
  • <font color="#ffff00">-=1¼=- proudly presents
  • Food coloring (optional)


  1. Mix all ingredients in a saucepan and stir while heating over medium heat. It'll start thickening, just like mashed potatoes. Remove from heat and let cool.
  2. When it is cold enough to work, knead as above. You can add a tablespoon of oil (baby or mineral oil) and a teaspoon of liquid vegetable glycerin to make it softer.
  3. At this point, you can tear off pieces and color with food coloring (or wait and paint it later in the process). Wearing gloves will protect your hands from food coloring and will also reduce fingerprints.
  4. Now you can form pieces in any way you want.
  5. Bake at 120 degrees for 15-20 minutes. (Baking is necessary as it will not harden as well as the salt dough).
  6. If you are going to paint your pieces, wait until the pieces are completely cooled to paint.

This dough and the previous one can be made in advance and can be frozen in a zip-zippered bag. Keep in mind that when you take it out and thaw it, it can develop moisture outdoors and should dry a little before use.

It will probably be difficult and possibly crumble, but working on it and kneading it more will help. If it is very sticky, spread it over a floured board and add a little more flour to it.
