Inart 1kg Plaster Powder is a white powder material, based on calcium sulfate, used to prepare molds, make castings, and create rigid pieces in sculpture, ceramics, and crafts. Mixed with water in the correct proportion, it forms a paste that hardens quickly and can be poured into silicone or rubber molds to reproduce shapes with good detail definition. It is also used to reinforce or repair already dried clay pieces before firing. Once dry, the plaster can be sanded, painted, or worked with sculpting tools to refine the final surface of the piece, allowing imperfections to be corrected without having to redo the casting. The 1kg package yields several applications depending on the size of the molds, making it a practical option for both art studios and schools, as well as for those working on sculpture, molding, or repair projects at home.
