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 and we here at Arachnid FX use it ourselves for many of our sculptures.
Chavant NSP clay has low odour and is certified nontoxic by the Art and Craft Materials Institute in the USA, conforming to ASTM D4236. Chavant NSP Clay may require some heat to soften it to your required working consistency. The ideal softening range is 44 55ºC. 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.
We reccomend using 99% IPA (available here aswell) to smooth out texture on a more gradual scale compared to white spirits
