Chavant NSP Medium Density Sculping Clay

Chavant NSP Plastilina was created with the intention of to eliminate sulfur from the composition, due to some possible problems with the different materials used to make the molds. The NSP line is made up of clays with a higher percentage of wax components, making the clay a little more resistant. Available in soft, medium and hard density, these clays have good adhesive qualities, flexibility and elasticity. Due to its strength, NSP allows you to cut detailed lines very cleanly without jagged edges. The touch is a little stickier compared to sulfur-based clay. NSP is used to create sculptures, but it can also be used to fill cracks in industrial work or even dams. NSP is subject to surface oxidation, if the clay remains in its original packaging, it will have a long shelf life, certainly months and perhaps years. If clay is repeatedly heated and cooled, oxidation is accelerated. NSP can be heated to soften it, but as it softens it also becomes stickier. Using small amounts of water, citrus-based solvents, latex paint removers, turpentine or white spirit as a lubricant on the clay surface will help achieve a smooth surface. NSP can be melted and poured into a mold, brushed or sprayed. The melting point is approximately 175°. Soft NSP is generally used at room temperature. Medium and hard NSP are normally heated to a temperature between 110° and 120° to soften them. When they return to room temperature they also return to their initial firmness. The recommended ambient temperature for working is 105°. Precautions: Due to the potential for oxidation, if you do not work on your piece for several months, you may want to keep it out of direct sunlight and cover it with a plastic bag to avoid direct contact with air. Wash your hands with soap after use.
