The product is supplied as a smooth, white clay that remains malleable during work and hardens at room temperature without the need for baking. After complete drying the material can be sanded, drilled and painted, making it suitable for finished models, ornaments and practical DIY fixes. Advantages The clay offers a uniform, smooth texture that is easy to knead and model, providing consistent results for detailed work. It hardens naturally at ambient conditions, eliminating the need for ovens or kilns and simplifying use in classrooms and craft spaces. Once dried the surface accepts common finishes such as acrylic paints and varnishes and can be sanded to refine shape and detail. Suitable for Sculpting small figures and reliefs Decorative ornaments and jewellery components School art and craft projects Home DIY repairs and model-making Hobbyist and workshop practice for shaping and finishing techniques Key specifications Type: air-drying, self-hardening modelling clay Colour: white Net weight: 300 g Texture: smooth, malleable Finish after drying: sandable and paintable Drying: hardens at room temperature without baking How to use Prepare a clean, flat work surface and knead the clay until it reaches a uniform softness. Shape and model the piece using fingers and modelling tools as required. Allow the shaped object to dry horizontally in a well-ventilated area; drying time depends on thickness and ambient conditions. Thicker parts may require longer drying—ensure complete dryness before further processing. After full drying, refine surfaces with fine sandpaper and apply paint, sealant or other finishes compatible with a porous, air-dried material. Usage recommendations For best results, keep pieces thin where possible to speed drying and reduce cracking. Store unused clay airtight and protected from drafts and direct sunlight to maintain workability. When painting, use water-based acrylics and allow coatings to dry thoroughly between layers; consider sealing finished items with a clear varnish to improve durability. ## FAQ ### How much does the KOH-I-NOOR self-hardening white clay 300 g cost, and is it available for purchase?
