MELTING BEHAVIOUR OF FELDSPAR PORCELAIN GLAZES

2011-3-24  The melting behaviour of feldspar porcelain glazes depends on the characteristics and homogeneity of the raw materials batch, with implications in kinetics of chemical reactions and achievement of thermodynamic equilibrium of oxide systems. During the heat treatment the glaze must be considered as a heterogeneous system changing its aggregation state and that is accompanied by structural changes of the formed melt

Feldspar – Micron

Feldspar is a critical material in the production of glass.It is also a crucial raw material in its production as it tends to act as a fluxing catalyst. As a fluxing catalyst, it reduces the temperature of quartz while simultaneously helping to keep the viscosity of the produced glass at the right correct range.
