Polymer clay is a form of PVC mixed with the liquid plasticizer for the purpose of obtaining a material of a consistency similar to that of clay. More known to us under the name of one of the producers, Fimo, Polymer clay is one of the newest and affordable materials for modeling. The following video is about how to get started with this art form:
It only strengthens the final baking, which gives us more freedom to experiment than air drying clay and can be combined with many types of materials to achieve unique effects and textures. The most important is to know that as far as the outcome of the initial plan your work, you can reuse it with ease.
In our market appeared a few years ago, first Fimo and Sculpey latest CERN and, in solid form, the most commonly used and in liquid form.
Clay fresh out of the package must be prepared before use, by kneading. We call this process ‘conditioning’ and the aim is that the particles align it correctly modeling. This alignment is easy to see where metal clays, which at first appear darker stripes, which disappear after kneading – darker color is given by small particles (a mineral composed of several bright foils, overlapping) the composition of the clay, which reflects light differently when they are not arranged.
Depending on the type of clay you are using this kneading may take more or less, but I advise you to start to knead for 3-4 minutes and sieved Fimo Classic Fimo Soft and 1-2 minutes Sculpey Premo and Studio.
The good news is that once you have ridden a piece of polymer clay, it no longer has mixed, however the idle state. I tested it with a piece of clay there a year old, and it was all ok.
Once you have prepared the clay, the most interesting part begins, modeling. If you use more colors, I recommend to prepare all before you start modeling, do not run inspiration while you struggle with kneading. One of the finer developments of the last decades is the creation of so-called Bioplastics, or degradable polymer material enabling us to have less impact on our environment.
The simplest way to make a clay bead is cut a piece of clay in the package (you can use the marks made by the manufacturer to obtain approximately equal-sized beads), kneaded it and rolling it between your hands, give her a ball shape. If out more oval least until the practice is proper form. Then with a toothpick, a hole from one side being careful only to highlight the point from the other side, remove the toothpick and insert it in the southern part – so the holes will be equal and no residues remain apart.
If a special texture is desired, then you can use a toothpick or other sharp object and gently press on the surface of the beads, following a pattern or randomly.
There are many tools that can be used, but two rules must be observed. First, the tools would be the clay raw material that reacts while they eat wood (do not forget the furniture green clay!), Certain types of plastic (eg boxes DVDs) and polystyrene. If the clay comes into contact with these materials for a short time, no problems, but do not forget to clean and to collect debris left after the workday.
For each type of clay, there is an optimum temperature for baking and cooking at this temperature, mentioned on the package like on that of Aardvark polymers and Nylon materials.
If the temperature is exceeded, then the clay will burn, releasing a pungent odor and pungent and white smoke that is difficult to remove from the house, so I recommend you to follow the baking temperature. The easiest is to use an oven thermometer and leave the oven to heat 10-20 minutes before putting baked clay so that no sudden changes in temperature. If the lowest temperature that can be maintained in the furnace is larger than recommended, try to leave the oven door slightly open.
Baking time (typically 30 minutes) is the time required for a piece of medium thickness – 2 cm – to cure. The very interesting part for us is that the cooking time can be much higher – up to 3 hours – because the clay burns due to high temperature and not cooking time, which is very useful when baked in several parts half.
I said that if they burn, the clay emits a pungent odor. Like most materials, polymer clay has a specific smell, different from brand to brand. The feel and smell during baking, but you should not worry, this is normal. If there is smoke and stings your eyes, then there are problems.
