New perspectives in the study of glasses and ceramic frits behaviour by means of the automatic images analysis supplied by the Heating Microscope.


The heating microscope has been used for many years for the research on the glass behaviour. Beside the classical determination of softwening point and sphere point, the hot stage microscope can supply more useful information, if the images of the softening glass are properly evaluated and if the heating rate can be modified in a wide range. The image processing applied to the study of the glass behaviour is discussed and new approches for the interpretation of the results fromt he hot stage microscope are suggested.
