More info: 
NSP was introduced in 1993. The intention was to eliminate the sulphur filler in a professional grade sculpting clay. Which often caused inhibition problems with various silicones & liquid rubber mold-making materials. The NSP product line consists of clay that contains higher percentage of wax components making the clay somewhat "tuffer" and more durable.
Available in Soft, Medium or Hard consistencies, these clays have good adhesive qualities, flexibility and strength. Because they are "tuffer" NSP tends to accept cut detail lines very cleanly, with no ragged and jaggered edges. The surface texture of NSP will be somewhat "grabby" when compared to sulphur-based clays and even the NSP. Soft is rather firm by some people's standards.

NSP is commonly used by artists for sculpture and is often used to fill cracks in industrial patterns or to build dams when making splash molds.
NSP Chavant Modelling Clay is subject to surface oxidation. If the clay is in its original package it will have a long shelf life, months and probably years. If the clay is repeatedly heated and cooled, the oxidation process is accelerated. Sometimes this characteristic is beneficial in handling or mold making since the surface becomes harder. Oxidation is rarely an issue.

Handling Tips:
NSP can be warmed to soften but as it softens it also becomes sticky. Using small amounts of water, citrus-based solvents, lighter fluid, latex paint removers, turpentine or mineral spirits as a lubricant on the surface of the clay will help to attain a smooth surface.
