Chavant NSP modelling clay
Chavant NSP (Non Sulphurated Plasteline) is a sulphur free professional oil based sculpting clay and is probably the finest quality non-drying modelling clay available. It is used extensively by many Sculpture and Film Studios in the USA for creating models and sculptures prior to having a mould made. We have in this respect found that the clays perform excellently when using silicone rubber to take a mould.
Chavant NSP Clay may require some heat to soften it to your required working consistency. The ideal softening range is 44-55C. It easily warms in hot air with no cracking or drying. The Clay has excellent adhesive properties sticking readily to itself or the armature wire. The Clay is tough but firm and has the ability to hold excellent detail. The Clay can be smoothed with water, or (taking adequate precautions) lighter fuel or turpentine spirit. The melting point is approximately 85C.
