Nepheline syenite is valuable in glass batches to achieve the lowest melting temperature while acting as a source of alumina. Like talc, this material can also be used at low temperatures to increase the thermal expansion of bodies to make glazes fit better (up to 50% talc is used for this purpose, but it cuts plasticity drastically unless vacuum pugged).
