Conservational chemistry

Polyacrylates can be used to protect ancient frescos, terracotta statuettes, and stone garden ornaments, as well as other porous objects according to D.N. Yemelyanov and colleagues at the Nizhni Novgorod State University in Russia. By tailoring the polymer blend to particular materials, whether clay, stone, or concrete, the researchers suggest that those hoping to conserve artifacts and ornaments will be more successful in their endeavors.
