I get this question alot, "I found your store by accident, what is polymer clay and what can I do with it?" 

Polymer clay is, as the name implies, a pliable, blendable polymer compound for artists and crafters. It's not a true clay - clay is fine particles of silicate suspended in water, whereas polymer clay is fine particles of polyvinyl chloride (PVC) suspended in plasticizer - but it can be used much like clay.

Original formulations of polymer clay remain soft until cured at relatively low temperatures, but air-dry polymer clays have recently been added to the market. Traditional polymer clay hardens by curing at temperatures created in a typical home oven (generally at 265 to 275 °F (129 to 135 °C), for 15 minutes per 1/4" (6 mm) of thickness), and does not shrink or change texture during the process. When properly conditioned and cured, most clays create items that will not break if dropped or normally stressed. Cured pieces may have additional layers or enhancements added and be re-cured with no ill effect. As long as the maximum curing temperature is not exceeded, there is no limit to the number of times a piece can be re-cured. After it has cured, the clay surface can be left as is, sanded and buffed, or finished with a water-based varnish.

Polymer clay can be used in many ways, a number of which have been generalized from other art or craft techniques. Some uses for polymer clay include:

• Sculpting. Hand-shaped items can be any size from "miniatures" to quite large.  Bas relief can also be created; clay clothing and accessories can be made for sculpted figures.

• Creating beads and jewelry of all kinds, such as pendants, earrings, barrettes, and buttons.

• "Cover"ing items made from materials such as glass, metal, cardboard, terra cotta, and some plastics. Popular items for covering include pens, eggshells, votive candle-holders, and switch-plates. Larger items, such as tables, can also be veneered.

• Creating vessels large and small. Jars, boxes, bowls, and container pendants can be created freestanding, or over permanent or removable armatures.
  

• Creating simulations or fauxs of many natural and fabricated materials such as jade, turquoise, marble, granite, metal, ivory, wood, leather, stained glass, mosaic, and cloisonne. 

• Onlaying clay with other materials to create collages.

• Creating paintings with polymer pastes, and bas reliefs.

• Creating practical utility items, such as frames, games and game pieces, dioramas, toys, mini-books, notebook covers, greeting cards, and postcards.
