Petalite can be used as a source of lithia in glasses and glazes where it acts as a powerful flux to reduce melting points and to lower thermal expansions.

In container glasses, lithia has been shown to both reduce the melting temperatures and improve glass production.

Petalite can also be used in refractories, such as kiln furniture, where it strongly reduces the coefficient of thermal
