    Newclay Hardener (454g)

    Newclay Hardener is used as an additive or coating to strengthen and protect air-drying clays, such as Newclay or other similar clay brands. It helps enhance the durability and hardness of the clay after it has dried naturally. The hardener is typically applied to the surface of the clay or mixed with the clay during the sculpting process. It creates a protective layer, making the clay more resistant to breakage, cracking, and water damage.

    This is a powder which must be whisked into hot water and solution left to cool. Apply solution only when Newclay pieces are completely dry. The treated piece can be hardened still further when placed in a cold oven and warmed up to a maximum temperature of 200c-400F.
