The clay shapes, scrapes and cuts smoothly and holds exceptionally fine surface detail. With a durometer of 19 Shore A, this is the softest variant in the Contour series, ideal for fine modeling work at room temperature (around 23 °C). The warm gray color makes profiles and surface textures clearly visible while sculpting. Contour S is sulfur-free and therefore safe to use in combination with silicone rubber, without inhibiting the cure of the mould.\u003c\/p\u003e\n\n\u003cp\u003eBecause Contour S does not harden, the clay remains reusable indefinitely. At room temperature the clay is firm and dimensionally stable; when warmed it becomes soft, spreadable or even brushable, after which it returns to its original firmness on cooling.\u003c\/p\u003e\n\n\u003ch3\u003eKey Benefits\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e\u003cstrong\u003eSulfur-free – \u003c\/strong\u003esafely combined with platinum and condensation silicones for mouldmaking, without cure inhibition.\u003c\/li\u003e\n  \u003cli\u003e\u003cstrong\u003eDurometer 19 Shore A – \u003c\/strong\u003ethe softest Contour variant, for smooth sculpting and fine detail work.\u003c\/li\u003e\n  \u003cli\u003e\u003cstrong\u003eButtery smooth hand feel – \u003c\/strong\u003ecomparable to sulfur-based clay, but silicone-friendly.\u003c\/li\u003e\n  \u003cli\u003e\u003cstrong\u003eHigh temperature resistance – \u003c\/strong\u003eonly softens from 57 °C and holds its shape in warm studio environments.\u003c\/li\u003e\n  \u003cli\u003e\u003cstrong\u003eSolvent-friendly – \u003c\/strong\u003esurface can be smoothed and dissolved with naphtha, mineral spirits or 99% isopropyl alcohol.\u003c\/li\u003e\n  \u003cli\u003e\u003cstrong\u003eReusable – \u003c\/strong\u003edoes not harden and retains its properties after reheating.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eTypical Applications\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eFigurative and industrial sculpting, from miniatures to monumental work.\u003c\/li\u003e\n  \u003cli\u003eMaster models for moulding with silicone rubber.\u003c\/li\u003e\n  \u003cli\u003ePrototyping and design models where fine detail matters.\u003c\/li\u003e\n  \u003cli\u003eTroweling onto EPS foam and mixed-material armatures as a shapeable coating.\u003c\/li\u003e\n  \u003cli\u003eBrushable build-up of thin layers on armatures after warming.\u003c\/li\u003e\n  \u003cli\u003eRestoration and reproduction work requiring reworkability.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eProcessing Instructions\u003c\/h3\u003e\n\u003col\u003e\n  \u003cli\u003eBuild an armature if needed; Contour S is not self-supporting for figurative work.\u003c\/li\u003e\n  \u003cli\u003eSculpt at room temperature (around 23 °C) for the finest detail; use traditional wood, plastic, metal or silicone tools.\u003c\/li\u003e\n  \u003cli\u003eWarm to around 57 °C to soften the clay; to 77 °C to trowel it with a metal spreader; to 85 °C to make it brushable.\u003c\/li\u003e\n  \u003cli\u003eUse a temperature-controlled slow cooker, laboratory oven or warming box.

In that case use naphtha, mineral spirits or isopropyl alcohol. Do not use isopropyl myristate, because the surface will then remain permanently soft and will not return to its original hardness.\u003c\/p\u003e\n\n\u003cp\u003eChavant is a leading American manufacturer of professional modeling clay for sculptors, model makers and the moulding industry.\u003c\/p\u003e\n\n\u003ch3\u003eProfessional Support\u003c\/h3\u003e\n\u003cp\u003eNot sure whether Contour S is the right hardness for your sculpting or mouldmaking project?
