Abstract

A water-soluble core consists of at least one alkali metal metasilicate and at least one alkali metal disilicate. Potassium, sodium and lithium meta- and di-silicates are referred to. The core may also include alkaline earth borates, tungstates, plumbates and silicates, crushed glass, graphite and iron or aluminium oxide.
