DIY Natural Cold Porcelain Clay (without Glue!)

DIY Natural Cold Porcelain Clay (without Glue!)

May 23rd 2018

Natural Cold Porcelain Clay is a perfect substitute for toxic polymer clay and allows for even finer detail and ease of sculpting. It's also incredibly inexpensive and super simple to make. The clay is air-dried so no need for baking and it dries to a light weight, luminous, stone-like texture. Perfect for kids through professional artists.

The DIY cold porcelain recipes that we found online all called for glue or PVA which can contain dangerous chemicals like xylene and toluene, so instead, we have a simple recipe using only three natural ingredients!

Here's what you'll need:

  • 1 cup of baking soda
  • 1/2 cup of cornstarch
  • 3/4 cup of water
  • 1 non-stick pot or skillet
  • Some Natural Earth Paint to decorate your creation!


1. Mix all of the ingredients in the pot/skillet and place on stovetop over medium heat.

2. Keep stirring the mixture until the clay thickens so that the clay can be lifted out of the pot in one piece (this may take up to 10-15 minutes!)

3. Set the clay aside to cool. When cooled, if the clay is too sticky to knead, place it back on the stovetop to heat again. You'll want the clay to be soft enough to knead, but not too soft where it sticks to your hands like a paste.

4. After the clay is properly cooled, it's time to CREATE! The clay takes several hours to a day to dry.

Options for coloring your porcelain:

I painted this leaf with Terre Verte Natural Pigment.

The possibilities with this clay are ENDLESS! I made this faux white marble ornament by using a cookie cutter and a gray marker.

If you have any leftover clay, store it in an airtight container and keep inside your fridge until you're ready to create more!
