Homemade Clay Polymer Clay Ideas

I make homemade clay because polymer clay contains harmful chemicals! Below is my recipe along with a few polymer clay ideas for you to try.

When the days are long and cold, I find projects to work on inside the house. I bake, make soap (of course!), crochet, read, or work on other craft projects. For the past few weeks, I’ve been making jewelry from polymer clay.

While working with the clay, I started thinking about all the chemicals that must be in it and that could be released during baking. Of course, I started thinking about how to make my own homemade clay. You’ll find my recipe below along with a few polymer clay ideas to try.

Homemade Clay: An Easy Clay Recipe

I remember making clay ornaments at Christmas when I was a kid. It was a simple recipe – nothing more than salt, flour, and water. It would get very hard just by air drying and then we would paint it. Here’s the exact recipe:

  • 1 cup flour
  • 1½ cups salt
  • 1 cup water (give or take a bit)

Mix the salt and flour in a bowl. Add water ¼ cup at a time, mixing well. You may not need all of the water or you may need a bit more depending on the humidity and temperature in the work area. Mix until you form a ball, then take it out of the bowl and knead it a bit. It should be firm but pliable. You can pinch off pieces and use food coloring to color them, or you can leave it and paint over it later. Form it into desired shapes. It will shrink some, but no more than about 10%. You can let it air dry, but baking it at 250°F will make it harder. Bake time will be dependent on the thickness of the pieces. For something the size of a ping pong ball, bake for about 20 minutes.

When it’s hard, let it cool completely. Then pieces can be painted, varnished, and even waxed for a high shine. They should keep for years.

Natural Polymer Clay Substitute

This homemade clay recipe is a bit more involved, uses no salt, and produces a finer finish.


  • 2 cups corn starch
  • 2 cups baking soda
  • 1¼ cups cold water
  • food coloring if desired


  1. Mix all of the homemade clay ingredients in a saucepan and stir while heating over medium heat. It will start to thicken, much like mashed potatoes. Take it off of the heat and let it cool.
  2. When it’s cool enough to work with, knead it as above. You can add a tablespoon of oil (baby or mineral oil works) and a teaspoon of liquid vegetable glycerin to make it more smooth.
  3. At this point, you can pinch off pieces and color with food coloring (or wait and paint them later in the process). Using gloves will protect your hands from food coloring and will also cut down on fingerprints.
  4. Form homemade clay pieces into desired shapes. Bake at 250°F for 15-20 minutes. (You do need to bake this as it won’t harden as well as the salt dough.)
  5. If painting your pieces, wait until pieces are completely cooled to paint.

This dough and the one above can be made in a large batch ahead of time and can be frozen in a zip-top bag. Be aware that when you take it out, it may develop moisture on the outside and should be dried a bit before using. It will probably be hard and possibly crumbly, but working it and kneading it more will help. If it is very sticky, roll it out onto a floured board and work a bit more flour into it.

For short periods of time, you can place it in a zip-top bag and leave it on the counter.

Homemade Polymer Clay Ideas

  • Any type of paint can be used to color the finished pieces. Be sure to paint after baking as some oil-based paints could be flammable. Coat with a sealer such as a varnish or paste wax. Buff after the wax.
  • If you do get unsightly fingerprints on the piece, you can sand the oven-dried piece with an emery board. Use a light touch and then finish with fine grain sandpaper, like a wet/dry type.
  • I’ve made some cool pieces by adding colored mica or glitter. It just needs to be worked into the clay before baking.
  • You can embellish your homemade clay with chatons or foil-backed rhinestones. Place the rhinestone on the top and then push it into the clay. Then pull the rhinestone out, add a dab of glue, and place the rhinestone back into the hole. You can bake most stones and they will be fine. Crystals and stones will not melt and they rarely ever crack at the low temperatures required for this clay.
  • Don’t want to make jewelry? Try some mushrooms or birds for the flower garden or embellish a box. Add clay to a mint tin to make a one-of-a-kind treasure box.

Tip: you can also make homemade paint for kids!

  1. Sandra says

    Hello, does this clay work as aromatherapy jewelry as well?
    Can I add essentials oils to it after it is finished? Just wondering if the oils will eat away at the clay.

    • Debra Maslowski says

      I haven’t tested it yet, Sandra, but I had that very though as I was writing the article. I’ll need to experiment and let you know! Because the clay isn’t plastic based, it will probably work well. The essential oils shouldn’t damage the clay.

    HI can you tell me how you make the holes for the jewellery balls, do you do it before baking them or after many thanks Denise

    • Debra Maslowski says

      I do the holes before baking, Denise. I use a wooden skewer and then after the beads are baked, I use a bead reamer to even out the hole on the inside if it needs it. You can find bead reamers at most craft stores and they are very cheap.
