A composition for the production of an open-pore foam product from essentially inorganic components contains, in addition to known components, a rock-forming solid substance, a curing agent, a foaming additive, and an at least partly alkali-soluble protein to produce open pores. The rock-forming component is a reactive solid substance selected from the group consisting of I finely dispersed oxide mixture containing amorphous silicon dioxide and aluminium oxide, II vitreous, amorphous electrofilter ash, III milled calcined bauxite, IV electrofilter ash from a brown coal power station, V undissolved amorphous silicon dioxide from an amorphous disperse powder-like, dehydrated or water-containing silicic acid or from high temperature processes (silica fume), VI metakaolin, and VII cement. The curing agent is an alkali metal silicate solution containing 1.2 to 2.5 mols of silicon dixoide per mol of potassium oxide and/or sodium oxide.
