Our native plant, the Jointed Glasswort (Salicornia herbacea, Linn.), was, as its name implies, also regarded as of value in the manufacture of glass. ---Description---It is a low-growing, annual herb, common in salt marshes and on muddy seashores all round the British Islands and was much used for this purpose.
Feldspar is a common raw material used in glassmaking, ceramics, and to some extent as a filler and extender in paint, plastics, and rubber. In glassmaking, alumina from feldspar improves product hardness, durability, and resistance to chemical corrosion.eldspars crystallize from magma as veins in both intrusive and extrusive igneous rocks and are also present in many types of metamorphic rock. Rock formed almost entirely of calcic plagioclase feldspar (see below) is known as anorthosite.
