Ever needed to model something in clay, but don’t have a kiln or a potter’s wheel? Don’t want to end up with just a cracked, blobby mess as the finished product? Well, self-hardening modeling clay may be the answer.

There are many self-hardening materials available which can be dried at room temperature and are very easy to use. For this project, I decided to make a miniature door for a relief painting.

I used milliput superfine modelling material. You can also use this material to mend cracked and broken ornaments as it sticks to ceramic. Handy when you’ve broken a relative’s precious vase.

You will need:

• modelling clay
• plastic knife and fork
• plastic lid

Where can I buy self-hardening modeling clay?

Self-harding modeling putty
There are many modeling materials, which can be dried at room temperature. The fact that they are self-hardening just means that you don't need to use a kiln. I used Milliput superfine modelling material. You can also use this material to mend cracked and broken ornaments as it sticks to ceramic.

Step One
This type of self-harding modeling putty comes in two separate packets. Read the instructions on whatever you decide to use, as they can vary. Break off the amount you think you will need.

Step Two
When the two substances are mixed together, this creates a chemical reaction that makes the material eventually harden. Make sure the two materials are kneaded and well-mixed together.

Step Three
Roll the kneaded doughy mixture into the required shape. Here I rolled them into thin sausages, which I shaped into a door.

Step Four
I marked out the lines going across with a knife. The idea was to make it look like wooden planks.

Step Five
I added a small door knob, a keyhole, a heart and hinges. Then I left the door to dry overnight.

Verdict for this project

Pros: Self-hardening modeling clay is an excellent material to use and is tough when dry. It is incredibly easy to use and retains the shape well. It allows you to create fine detail and you can even sand it when dry. The material didn’t shrink or change shape too much when dry.

Cons: Milliput modeling putty sticks to whatever it is near (even to the plastic lid it was on). So if you don’t want it to stick, loosen the object from whatever it’s resting on before leaving it to dry. (However, it is a good material to repair damaged ceramics for this reason).
