How to make Clay at home...

There are four ways I got from web to make Clay at home (Cold Porcelien ).

NB : This is not Polymer Clay

Method 1

1. Use this recipe for a homemade version of polymer clay. This clay behaves in much the same way as commercial polymer clay but it might shrink more. It can shrink up to 30% by weight, not in size. Be aware of this when working on projects.You may want to build your project a bit bigger so that when it shrinks it will be the correct size.
2. Pour ¾ cup of glue and 1 cup cornstarch into the non-stick pot. The pot should be either sitting on the counter during this step or if it is perched on the stove, make sure the flame is not on. Stir well until fully combined. PVA wood glue works best for this recipe although the normal white children’s glue will work well also. The children’s glue may result in clay that is a bit weaker than clay made with wood glue.
   
3. Add 2 tablespoons of mineral oil and 1 tablespoon of lemon juice to the glue and cornstarch mixture. Stir well until completely blended. If you cannot find pure mineral oil then you can use petroleum oil (not jelly) or baby oil as a substitute.If you want, you can add food coloring or acrylic paint to the mixture at this point to color it. Be careful not to add too much paint or else you could change the texture. If you want vibrant colors then you should simply paint your creation once it is made.
4. Transfer the pot to the stove. Simmer over low heat/flame. As you heat up the stove, stir constantly to keep the liquid ingredients moving. Don't let the mixture sit still, as this will compromise the integrity of the clay’s texture.
5. Continue stirring the mixture until it resembles mashed potatoes. Once it turns to the mashed potato consistency, it’s time to remove from the heat/flame and place onto a cool/flat surface. Consider placing a hot pad or towel on the counter to protect your counter tops.
6. Add a small squirt of mineral oil to the mushy clay. The oil will coat and grease your hands as you knead it so that it does not stick to your hands.
7. Transfer the clay to the counter top to work and knead. You should do this while it is as hot as possible, as long as your hands can handle the temperature. You can also use either rubber or work gloves to protect your hands.
8. Knead the dough until it's smooth. The consistency should appear like well-worked pizza dough and be completely blended together. Roll into a ball when finished.
9. Store the finished clay in a re-sealable freezer bag that can be kept in the refrigerator. To keep clay fresh and avoid having it harden, remove as much air as possible before sealing the bag and storing it. If the clay is still warm, place in the bag but leave a small amount of the bag open. Once it has cooled completely, then you can seal and store it.
10. Use your dough to create something. Now that you have made your dough, you can use it to create anything you choose. When working with the dough it helps to put a little hand cream on your hands to allow you to smooth the clay easily. Allow your creation to dry for at least 24 hours, or more if it is not yet dry. Paint with your choice of paint. Tempura paint works well but other types will work as well. You should paint even those areas that you want to remain white because it can start to look translucent if you do not.

Method 2:

1. Use this recipe for homemade polymer clay for a version that does not crack.This recipe has a higher ratio of glue, which makes it much stickier but also prevents cracks. This recipe also dries much faster, taking only about 30 minutes.However, after making the recipe you will have to wait at least one night and preferably a week until you can use the dough. This makes it less sticky.
2. Wear old clothes or an apron. This will keep your clothes clean and tidy during the process.
3. Mix the water and glue in a non-stick pot and boil for two minutes. Mix ½ cup water with 2 cups pva (wood) glue in a non-stick pot. Boil them for two minutes while stirring constantly and then remove from the heat. You can use any white children’s glue but wood glue works best for this recipe because it is stronger.
   
   
   
4. Mix the cornflour with ¼ cup of water in a mixing bowl and pour into the blend. Put the cornflour and water in a bowl and pour into the pot of boiling glue and water. Mix the ingredients well. Cover the dough with plastic while it is cooling. If using food coloring, add one to two drops and adjust as needed. Otherwise you can paint the clay after drying.
5. Sprinkle cornflour on a suitable work surface. Remove the dough and knead well. Continue kneading and adding extra cornstarch until the dough becomes less sticky.
6. Store in an airtight bag to prevent drying out. Put the dough in an airtight bag to prevent it from drying out while you wait until making use of it.

Method 3:

1. Use this method for a traditional-style recipe from Latin America. This recipe is very popular in Latin America and makes useful clay. Many recipes call for 10% formaldehyde or formalin but this has been replaced with white vinegar in this recipe for a safer, non-toxic version.
2. Mix the cornstarch, water and glue into a Teflon-coated pot. First mix 1 cup cornstarch with ½ cup water in a Teflon-coated pot over low heat until it is completely dissolved. Once the cornstarch has dissolved, add and mix in the 1 cup glue.
   
3. Add the glycerin, cold cream and vinegar to the pot and mix. Add 1.5 tablespoons of glycerin, 1.5 tablespoons cold cream with lanolin and 1.5 tablespoons white vinegar to the pot. Continue cooking on low heat while stirring constantly until a dough forms and begins to come away from the sides of the pot. Be very careful not to overcook or else the dough will harden. Glycerin is a common baking ingredient that you should be able to find in the baking section of the supermarket. Find cold cream with lanolin in the cosmetics section of the store.
4. Knead the dough with lotion on your hands. Allow the dough to cool with a damp cloth used as covering. Once you can handle the dough knead it into a smooth clay consistency. It is ready to be molded however you wish. Allow your creation to dry for at least three days in the air.Oil paints and acrylics can be used to paint your creation once you have allowed it to dry.
5. Store in plastic wrap. Store in plastic wrap and keep in a cool, dark place.

Method  4:

1. Use this recipe for very strong clay. This recipe involves additional ingredients but it results in very strong clay that can be dropped from one meter high and not break.
2. Combine all the ingredients except the cornstarch in a non-stick pan over low heat. Mix 1 cup PVA glue, ½ tablespoon stearin (stearic acid), 1 ½ tablespoon glycerin, 1 ½ tablespoon Vaseline and ½ tablespoon citric acid in a non-stick pot over low heat. Mix completely. Use the lowest heat possible to heat up the pot.
3. Add the cornstarch little by little and keep stirring. Add the ½ cup cornstarch little by little into the mixture, stirring the whole time. Adding the cornstarch little by little prevents lumps from forming. Keep mixing the clay until you can lift the clay up from the pan. It will get stickier and stickier and then heavier and very hard to stir but you must continue until you can lift it out of the pan.
4. Knead the clay for about 20 minutes. Place the clay on a table on top of non-stick paper (baking paper). It should be hot, a little sticky and a little lumpy. Knead the clay for about 20 minutes until all the lumps disappear and the clay becomes smooth and no longer sticky. Allow the clay to cool down for a bit if it is still hot when you finish kneading.
5. Store the clay in a sealed plastic bag. Store the clay in sealed plastic bags to prevent it from hardening before use. Make sure you press all the air out of the bag before sealing. Use the clay to make whatever you prefer and paint using acrylic paints.

   

   Finally it should look like this !
   
   
   
   
   

   It needs not be baked... will get harden itself in contact with air. Try it for your initial creative experiments.
