Part of the innovative DAS range, DAS Stone is an air-hardening clay with a natural, stone-like finish perfect for architectural modelling work, restorations or decorations. Made in Italy since 1963, DAS is a malleable, self-hardening range of modelling clays available in several colours/finishes perfect for a variety of creative projects. These water-based, dermatologically tested clays contain no softeners for a non-toxic, PVC, solvent & gluten-free range of clays suitable for everyone from ages 3+. DAS is a self-hardening clay that requires no baking. Once finished, simply leave your work in a dry, safe place and DAS will slowly dry (24hrs per cm of thickness) to a structurally sound finish able to be decorated using paints, markers, glues or other embellishments.
