Polymetal acrylates, permanently filled with an excess of a polyvalent metal carbonate and saturated with water, exhibit properties ranging from moldable elastomers to moldable clays. Polyvalent metal carbonates may be selected from zinc carbonate, cadmium carbonate, cobalt carbonate, calcium carbonate, magnesium carbonate, strontium carbonate, barium carbonate, copper carbonate, lead carbonate, nickel carbonate, iron carbonate, and manganese carbonate. Water, or water and water miscible organic liquids (such as alcohols or ketones which are plasticizers for the polymer) provide flexible compounds with integrity, while removal of the liquid provides hard plaster-like compounds. Rewetting the compounds provides the original maleable properties.
