A method providing measurement of melting temperature of glaze powder particles is described. The principle of the method is a direct measurement of the light transmittance through a layer of frit powder at a constant heating rate. Examples are given to measure melting temperatures of a commercially produced frit and sodium chloride and sodium phosphate (NaPO₃) chemicals, respectively. Specific features of the present measurement method are discussed with respect to the other similar methods. |
