The Mont Marte Premium Air Hardening Modelling Clay Terracotta 500g is ideal for professional modellers, artists, and students. This heavy-bodied clay is flexible after kneading, and because it dries slowly, you may take your time shaping it into the pattern you choose. Once dried, the clay is suitable for free-form sculpting and may be sanded, drilled, painted, or disappeared. Imagination may be used to make almost any decorative thing. Dries to earthenware hardness in around 24 hours (depending on thickness). Traditional pottery processes can be used in non-traditional ways like stamping or incorporating items into your work. Mont Marte Premium Air Hardening Modelling Clay may be worked with standard pottery tools.
