What Is The Role Of Feldspar In Glazes
Feldspar's Role in Glass Formation Feldspar as a Flux. One of the primary functions of feldspar in glazes is its ability to act as a flux. As a flux, feldspar lowers the melting point of the glaze mixture, allowing it to vitrify and form a glassy structure when fired. This glassy matrix provides a smooth and glossy finish to the ceramic surface.
