3. **Air Dry Clay (Flour Clay):** A versatile option that dries hard at room temperature, suitable for a wide range of projects.
4. **Polymer Clay Alternative (Conditioner Clay):** A pliable and colorful clay made with hair conditioner and cornstarch; doesn’t require baking.
5. **Paper Clay:** Lightweight and durable, made from paper pulp and glue; excellent for sculptures and decorative items.

Recipe 1: Salt Dough Clay

Salt dough clay is the easiest and most accessible clay to make. It’s perfect for kids’ crafts, holiday ornaments, and simple sculptures. However, it is brittle and not very durable, so keep that in mind for your projects.

**Ingredients:**

* 1 cup all-purpose flour
* 1 cup salt
* ½ cup water (more or less, as needed)

**Instructions:**

1. **Combine Dry Ingredients:** In a large bowl, mix together the flour and salt. Make sure the salt is evenly distributed.
2. **Add Water:** Gradually add the water, mixing with your hands or a spoon until a dough forms. Start with a little less water and add more if needed, as the exact amount can vary depending on the humidity.
3. **Knead the Dough:** Turn the dough out onto a lightly floured surface and knead for about 5-10 minutes, until it becomes smooth and elastic. If the dough is too sticky, add a little more flour. If it’s too dry, add a tiny bit more water.
4. **Shape and Create:** Now you can start shaping your salt dough into desired forms. Use cookie cutters, rolling pins, stamps, or your own hands to create ornaments, sculptures, or other decorations.
5. **Bake or Air Dry:**
* **Baking:** Preheat your oven to a very low temperature (around 200°F or 95°C). Place your creations on a baking sheet lined with parchment paper. Bake for 2-4 hours, depending on the thickness of your creations. Check them frequently to prevent burning. They should be hard when done. Thicker pieces may require longer baking times.
* **Air Drying:** Place your creations on a wire rack or a piece of parchment paper in a well-ventilated area. Air drying can take several days to a week, depending on the humidity and thickness of the items. Rotate them occasionally to ensure even drying. Air-dried salt dough is often more prone to cracking.
6. **Cool and Decorate:** Once the salt dough creations are completely dry and cool, you can decorate them with paint, markers, glitter, or any other embellishments you like. Acrylic paints work well for a durable finish. Seal with varnish for added protection.

**Tips and Tricks for Salt Dough Clay:**

* **Lumpy Dough:** Ensure the salt is finely ground and thoroughly mixed with the flour before adding water.
* **Cracking:** Slow drying helps prevent cracking. If baking, use a low temperature. For air drying, cover the creations with plastic wrap loosely for the first few hours to slow down the drying process.
* **Storage:** Store uncooked salt dough in an airtight container in the refrigerator for a few days. However, it’s best to use it fresh.

Recipe 2: Baking Soda Clay (Cornstarch Clay)

Baking soda clay, also known as cornstarch clay, creates a smooth, porcelain-like finish. It’s perfect for delicate projects like jewelry pendants, small ornaments, and fine details. Unlike salt dough, it is more durable, though still prone to breakage if not handled carefully.

**Ingredients:**

* ½ cup cornstarch
* ¾ cup water

**Instructions:**

1. **Combine Ingredients:** In a saucepan, combine the baking soda, cornstarch, and water. Stir well until the mixture is smooth and there are no lumps.
2. **Cook Over Medium Heat:** Place the saucepan over medium heat and stir constantly. The mixture will initially be thin and opaque, but it will gradually thicken as it heats up.
3. **Continue Stirring:** Keep stirring continuously to prevent the mixture from sticking to the bottom of the pan or burning. This is important to achieve a smooth, even texture.
4. **Remove From Heat:** After about 10-15 minutes, the mixture will start to resemble mashed potatoes. It will become thick and pull away from the sides of the pan. At this point, remove the saucepan from the heat.
5. **Cool and Knead:** Transfer the hot clay to a plate or bowl and cover it with a damp cloth or plastic wrap. This prevents a skin from forming on the surface. Let it cool completely. Once cooled, knead the clay for a few minutes until it becomes smooth and pliable. If it’s too sticky, sprinkle a little cornstarch on your hands and the work surface.
6. **Shape and Air Dry:** Shape the clay into your desired forms. This clay dries very hard and brittle, so consider adding a wire loop for hanging if creating ornaments before the clay dries. Place your creations on a wire rack or parchment paper and let them air dry. Drying time can vary from 24 to 48 hours, depending on the thickness of your creations and the humidity. Rotate the pieces occasionally for even drying.
7. **Finishing Touches:** Once the clay is completely dry, you can sand it lightly with fine-grit sandpaper to smooth out any imperfections. Then, you can paint it with acrylic paints or watercolors. Seal with a varnish or sealant to protect the finish and add durability.

**Tips and Tricks for Baking Soda Clay:**

* **Lumpy Clay:** Make sure the cornstarch and baking soda are well combined before adding water. If lumps persist, try sifting the dry ingredients.
* **Cracking:** Drying too quickly can cause cracking. Cover the creations with plastic wrap loosely for the first few hours of drying to slow down the process.
* **Sticky Clay:** Kneading a small amount of cornstarch into the clay can reduce stickiness.
* **Storage:** Store uncooked baking soda clay in an airtight container in the refrigerator for a few days. Re-knead before using.
