Baking Tips: How to make the clay dry faster?
This clay will harden (air dry) in about 3 to 5 days. Or you can speed up the drying process by baking it in the oven. Generally with air dry clay you want to let it dry slowly to prevent cracking.
To bake it in the oven, preheat an oven or toaster oven to 200 degrees Fahrenheit. Place the items on a foil or parchment lined baking sheet and bake for 1 to 1 1/2 hours, flipping the objects over half way through. Turn off the oven and allow the items to cool to room temperature in the closed oven before taking them out.
What can I make out of this clay?
There are so many items you can sculpt out of air dry clay! You can make little pinch pots or plates, or you can create a jewelry holder.
Try using a rolling pin and cookie cutters to cut out clay ornaments. You can also sculpt little figurines, like a clay turtle or a clay frog, or even clay mushrooms.
How long will this homemade clay last?
This clay will last up to 2 weeks. Wrap the unused portion in plastic wrap and store it in an air tight container (the plastic wrap is important if you don’t want it to dry out).
A batch of clay that we made over a week ago is still soft and workable. This homemade clay is even nicer to work with after it sits for a few days.
Can this clay be coloured?
Much like with homemade playdough, food colouring works well to colour this homemade clay. If you want one colour of clay, add the food colouring to the water before mixing it with the dry ingredients.
For several colours of clay, wait until the clay has cooled to room temperature. Separate it into balls (4 balls for 4 colours, for example) and knead the food colouring into the clay until the ball is evenly coloured. You can do this kneading in a baggie to keep the mess to a minimum.
We chose to leave our clay white and painted our sculptures with acrylic paint to give them colour.
How to Make Homemade Clay
Materials:
- 1 cup Baking soda
- 1/2 cup Cornstarch
- 3/4 cup Water
Equipment:
Instructions:
Step 1: Cook the Clay
- Add baking soda, cornstarch, and water to a pot and stir together.
- Place the pot on a burner over low to medium heat. Stir continuously until the mixture starts to pull away from the pot and it forms a "mashed potato" consistency.Pull the pot off the heat immediately when it reaches this thickness. Do not overcook!
- Put the clay into a bowl or spread it out on a baking sheet to cool. Let the clay reach room temperature before working with it.It will take at least half an hour to cool down.
Step 2: Use the Clay
- The texture of the clay should be very soft and moldable, but not sticky. If the clay sticks to surfaces, or your hands, dust the work area with cornstarch.
- You can roll out the clay or form it with your hands.
- Cookie cutters are a good tool for making shaped items, such as ornaments.Allow the clay to air dry for 3 to 5 days. Or bake it in the oven at 200F for 1 to 1.5 hours, flipping the piece half way through (see baking tips above).
- Your air dry clay recipe is complete!

I love the idea of an all natural, homemade clay, buy my dough didn’t come together at all. Just a soupy, sandy mess. The longer it was on the heat, the more watery it became. Does this seem right? I had it on the stove for about 10 minutes. Did I not cook it enough?
Hi Lesley! 10 minutes cook time sounds about perfect, so I’m not sure why it wouldn’t work for you. The only thing I can think of is that you didn’t get the mixture hot enough. Cornstarch needs a certain amount of heat in order to thicken.
Maybe the cornstarch was old or expired? It won’t thicken enough if it is too old. I learned that while making lemon meringue pies!
Hi Everyone!
I found this recipe when I was in need of some clay to make a small pumpkin scary for a friend’s daughter. I have to say that I have been raving about it since using it! its the BEST homemade clay I’ve ever used!!!
Wow, Suzette, thanks so much!! We’re so glad it’s worked well for you too! 🙂
I almost gave up on diy Air Clay until I came across this recipe! I made Oggie Boogie face mask using this recipe and it WORKED! I’m so HAPPY I came across this recipe because the other two I tried fell apart. I will FOREVER be using this recipe for LIFE! Thank you for this recipe because now my daughter has her homemade Oggie Boogie that turned out AWESOME! Happy Halloween 🎃.
We’re SO happy to hear this!! Honestly it’s awesome to see other people enjoy this recipe. 🙂 Happy Halloween to you and your daughter as well!
This looks wonderful. About how many circular ornaments will your recipe make – assuming the diameter is about the size of a large soup can?
Hi Vanessa! Hmm, good question. This recipe makes close to 2 cups of clay… I’d say it could probably make 10 – 12 ornaments, but that’s just a guesstimate. 🙂
Is this clay waterproof?
Hi Shaaron! No, air dry clay is not waterproof.
I just made a batch and I was just about to give up because it was not working when it almost instantly came together in a lump of beautiful clay. Excellent!
So glad it worked out for you, Tony! 🙂
I can hardly wait to try this recipe for Air Dry Clay. How thick do you roll the dough to make cookie cutter shaped ornaments? Thank you.
Hi Marys! You’ll want to roll the clay to about 1/4 inch thick — or even a little thinner — to make ornaments.
I’m so excited to make tree ornaments and tree garland !!!
I am a complete newbie …
Wondering if the finished dried ornaments will be smooth or will they look and feel granular ???
Once dry, will the clay crack and break easily ???
Once dry, is the clay paintable ???
Hi Tam! The finished clay is quite smooth, and yes, you can definitely paint it! We made our clay turtles with this recipe and painted them with acrylic paint after they were dry.
The dough came together so well for me and we made ornaments but they have all dried SO cracked that we can’t use them! Do you know what may have caused this?
Hi Annette! It’s possible there was a bit too much water content in the clay when you rolled them out, or maybe they were a bit too thin? Air dry clay ornaments should be at least 1/4 inch thick, or else cracking does become an issue.
