This air drying clay is referred to as cold porcelain because it dries to resemble real porcelain. But unlike polymer clay, it's non-toxic and does not need to be cooked or cured. A favorite of many artists, cold porcelain allows you to create simple projects such as this clay vase, or very intricate pieces where you can add delicate details to your sculpture.
How to Make Non-Toxic Porcelain Clay
Place 2 tablespoons of lemon juice into bowl.
Slowly mix all of the ingredients together until you achieve one cohesive mixture.
Continue stirring the mixture for approximately five minutes, or until the majority of the lumps have disappeared.
Once lumps have disappeared, place the bowl into your microwave and heat for 15 seconds. Remove the bowl from the microwave and stir continuously for 1 minute. Repeat the 15 second heating/1 minute stirring technique eight times.
Microwave temperatures vary from brand to brand, so pay close attention to your mixture and do not over heat. The mixture should go from a liquid form to a lumpy sticky ball.
After you have heated and stirred your mixture 8 times, sprinkle starch or hand lotion over your work surface. At this time, also apply hand lotion or Shea butter on your hands so to avoid dough sticking to your fingers and hands.
Knead the dough for approximately ten minutes or until it's no longer sticky.
You may need to re-apply lotion onto your hands throughout the process.
Wrap the clay in plastic wrap and place in an airtight container.
Allow clay to rest for 24 hours, after which you can unwrap the clay and knead. Well made cold porcelain clay should be easy to mold and capable of sculpting very thin and delicate designs.
To tint your clay, simply apply acrylic paint right onto clay and knead until paint has mixed thoroughly with the clay.
The more paint you use, the deeper or saturated the color will be. However as most paints contain water, it's recommended to add the paint a little bit at a time to avoid your clay becoming sticky.
Once your clay is tinted, it's ready to be used. Mold your clay in desired shapes and allow to air dry. Clay will be completely dry in 24 hours, but it might take longer depending upon the thickness or size of the piece.
Easy to work with, cold porcelain is highly moldable, so any errors you may make can be easily corrected by simply adding moisture to the piece.
An alternative to pre-tinting the clay is to paint it once the clay is dry. To do this, simply allow clay to dry completely and use acrylic paint as desired.
To stick pieces together, you may need to apply a little water to each piece. Lubricating your piece with water while sculpting can help you a great deal.
