Polymer clay is a type of hardenable modeling clay based on the polymer polyvinyl chloride (PVC). It typically contains no clay minerals, but like mineral clay a liquid is added to dry particles until it achieves gel-like working properties, and similarly, the part is put into an oven to harden, hence its colloquial designation as clay. Polymer clay is generally used for making arts and craft.

Art made from polymer clay can now be found in major museums.

    Bakelitean early plastic, was popular with designers and was an early form of polymer clay, but the phenol base of uncured Bakelite was flammable and was eventually discontinued. Polymer clays were first formulated as a possible replacement for Bakelite. While it was not suitable for use in her factory, Kruse gave some to her daughter Sophie, who was known in the family as "Fifi", who successfully used it as modeling clay. Polymer clays contain a basis of PVC resin and a liquid plasticizer[4] making it a plastisol.

    Polymer clay plastisol is also categorized as a plastigel because of its rheological properties. This plasticity is what makes it useful as modeling clay as opposed to putty or paste. Plastigels retain their shape even when heat is applied, which is why polymer clay does not melt or droop when oven cured. The base resin can be modified in various ways. Mineral oil, lecithinand odorless mineral spirits can be added to reduce its viscosity or alter its working properties.

    Small amounts of zinc oxidekaolinor other fillers are sometimes added to increase opacityelastic modulusor compression strength. Polymer clay is available in many colors, which can be mixed to create a wide range of colors or gradient blends.

    Special-effect colors and composites include translucent, fluorescent, phosphorescent, and faux "pearls", "metallics", and "stone. Polymer clay remains workable until cured. Professional polymer clay brands shrink very little when cured [7] Brands of polymer clay include CernitOytraFimoKato PolyclaySculpeyand Crafty Argentina.

    A home pasta-making machine is a popular multi-purpose tool for polymer clay artists. It is used to create sheets of uniform thickness, to mix colors or create variegated sheets, and to condition soften the clay.

    This involves kneading the clay by hand, passing it between two rollers, or using a low-shear mixer to break up any resin particle adhesions. Once conditioned, the clay will remain pliable until the particles eventually re-adhere. Oven-hardenable PVC plastisol, "liquid polymer clay," is a complement to polymer clay that can be used as an adhesive to combine polymer clay what is it, or to create various effects.

    Pigments, chalk pastel, and regular polymer clay can be added to make colored liquid clay. The liquid can also be poured into molds to produce cast parts.

    Polymer clay safety is the subject of concern specifically regarding the long-term effects of exposure to certain phthalate plasticizers that have been classified as endocrine disruptors. If the instructions on the package are followed i.

    If the clay does burn because of a mistake or if the oven malfunctions, a small amount of hydrogen chloride gas could be released, which may cause odor and some eye or nose irritation. The amount of hydrogen chloride gas released from the clay could cause a health problem. Due to the testing requirements and regulations, clay products that would be used to hold or serve food or how to iron a sheet are not recommended or intended for these applications.

    Plasticizers remain in the cured product and can leach out, making it a potential health hazard for both the modeler and end user. Restrictions on use of certain phthalates took effect in in both the European Union and United States. Polymer clay can be used to make a variety of folk-crafts and jewelry. Air dry formulations, sometimes referred to as self-hardening polymer clay such as Deco, cold porcelainetc.

Learn more Polymer clay gets harder as it gets older, making it difficult or even impossible to shape and use, especially if the clay has been left uncovered.

    You can use several methods to revitalize the clay, from hand-kneading to adding oils or diluents. To soften polymer clay, hold it in your hands so your body heat can warm it up. If the clay is especially hard, lay a hot water bottle over the clay for about 20 minutes, or microwave it for 10 seconds at a time until it is warm.

    Once the clay has warmed, knead it with your hands for about a minute, then roll out the clay into a snake shape. The friction from rolling out the clay will help make it soft and pliable.

Related Articles. Article Summary. Method 1 of Warm the clay with body heat. If your clay is only slightly hard, you may be able to soften it just by warming and kneading it with your hands. Before you start kneading the clay, hold the clay in your hands to warm it.

    You can also warm it using the heat of your body by sitting on top of it. If your clay is only a little bit hard, you may be able to restore its softness just using body heat. No matter what method you use to soften clay, always warm it first. Warm the clay using a heat source.

    If the clay is especially hard, you may need to use a heat source to soften the clay. Lay a hot water bottle over your clay for twenty minutes to help soften it. This can cause the clay to start to bake, which will make it unusable.

    Additionally, you can put the clay in the microwave for second spurts until it is warm. Roll the clay in your hands. Once the clay has softened, roll it between your hands in a snake shape, then roll it into a ball. Rolling the clay creates friction, which helps to soften it. Roll with a rolling pin. If the clay is still too hard to roll with your hands, you may need to use more force. Lay the piece of clay on a clean cutting board or on the counter, then press down on the clay to flatten it out as much as you can.

    Then roll the clay out with a rolling pin. After you roll it out, it should be warm enough to roll with your hands. Hit the clay with a mallet. If your clay is too hard to roll out with a rolling pin, you will need a large amount of force. Break the clay up into as small of pieces as you can, then place the clay pieces in a sealed plastic bag. Wrap the bag with a cloth and put it on the floor or on the cement or pavement outside. Using the mallet will break up the clay and add friction which will make it softer.

    After you have used the rubber mallet, take the clay out of the bag and roll it with your hands into a ball. Knead the clay. After you have rolled the clay, knead the clay with your hands on a counter just as you would with dough. Use as much force as you need to pull apart and reshape the clay. Method 2 of Add in a liquid diluent. A liquid diluent is one product on the market that softens unworkable clay.

    Many diluents are manufactured by the companies that make polymer clay, and they are made specifically for rejuvenating old clay. Add in liquid diluents a drop at a time as you knead the clay.

    Adding too much can make the clay mushy. Liquid diluents can be used as a glue, and therefore may add stickiness to your clay. If your clay is becoming too sticky, wrap it in a paper towel to absorb some of the stickiness. Use a bar of clay softener. There are also several clay softeners that come in bar form. Instead of being liquids that you add, the bars are made of a neutral mixing compound that helps your clay become more workable. Use one part of solid clay softener to five parts of clay.

    Warm the clay, then add the bar clay softener and knead until the clay and the clay softener are mixed. Bar clay softeners are whitish colored and therefore work best with highly saturated clay. Be aware that adding too high a ratio of bar clay softener can dilute the color of the clay.

    Add in liquid clay. Liquid polymer clay is another material that can be used to make hard clay more pliable. Use liquid polymer in a similar way as you would the diluent, adding it drop by drop and kneading the clay in between drops until the clay has reached the right consistency.

    You can also use tinted liquid clay, but it will slightly change the original color. Add mineral oil. Even though mineral oil is not made specifically for helping to soften clay, it does work wonders to soften and improve the texture of polymer clay. Add in a drop of mineral oil at a time, kneading in between each drop until the clay is workable. Rub the clay with petroleum jelly. To use petroleum jelly, dab a small amount on your fingers and rub it into the clay.

    Then knead the clay to mix in the petroleum jelly. Keep adding more until you reach the optimal consistency. Combine hard clay with fresh clay. Another option that you have is to simply tack on fresh clay to the hardened clay, then knead the clays together. The more new clay that you add, the softer the combined clay becomes. Knead the clay with your hands until the clay feels consistent throughout. Method 3 of Chop the clay with a knife. If you are working with very hard clay, you may need to use a food processor to really break down the clay and warm it up.

    Before you put the clay pieces into the food processor, first use a sharp knife or cleaver to chop the clay into the smallest pieces that you can. Place the clay and a softening agent in a food processor. Once you have chopped the clay as much as you can, take the chopped pieces and put them in a food processor. If you wish, add a few drops of diluent or liquid polymer clay to the food processor as well to further help soften the clay.

    Then place the lid on the food processor. Try to get a separate bowl and blade for mixing clay because unless you clean them extremely thoroughly it is not advisable to use the same ones for food and clay.

    Grind in ten-second spurts. Use the highest setting on your food processor to grind the clay. Grinding the clay will separate it into smaller pieces and soften it, making the clay easier to work with.
