This work concerns the melting of flat glass batches with increases in alumina content from 0,35 to 0,45 to 0,7 % AI<sub>2</sub>O<sub>3</sub>. The alumina was provided by hydrated alumina, nepheline syenite and Calumite. The introduction of blast furnace slag (Calumite) showed the most advantageous melting behaviour. The use of Calumite had advantages over the other sources particularly through a decrease of the soda ash in the batch. Nepheline syenite showed no advantage over hydrated alumina either in melting behaviour or viscosity-temperature relation.
