Sculpey (often misspelled as Sculpy) is the brand name for a type of polymer clay that can be modeled and put into a conventional oven to harden, as opposed to typical , which require a much hotter oven, such as a kiln. Until it is baked, Sculpey has a consistency somewhat like Plasticine. Its main competitor is the German brand Fimo. It is sold in many colors, but can also be painted once it’s baked. Sculpey has become popular with modeling artists, jewellery makers, and other craft work.
The primary ingredient in Sculpey is polyvinyl chloride, augmented with fillers, and colorants. Aside from the hazards of overheating and combustion, which can generate hydrochloric acid and other toxins, Sculpey is nontoxic both before and after hardening.

Sculpey closely resembles Fimo, another brand of polymer clay. Sculpey has a less rigid composition which better suits modeling, while Fimo is better suited for twisting into cane and bead making because the colors do not blend together as readily. The plasticity is controlled by the amount of oil suspending the polymers in the "clay".
Today, Sculpey offers six variations of polymer clay: Sculpey Soufflé, Sculpey Premo, Sculpey III, Sculpey BakeShop, Super Sculpey and Sculpey Original. It also manufactures various liquid clay products and polymer clay tools.
Marbling is one of the simplest techniques used with polymer clay. It involves mixing different colors of polymer clay together to form a pattern. As the clay is mixed, the pattern becomes smaller and smaller, until the two colors are completely blended.
Colors can be mixed by combining various colors of clay, alcohol inks, mica powder or paints.
Mokume-Gane is a technique borrowed from metalworking. It involves placing several sheets of clay on top of each other and then pushing an object through it.
