It describes the robotic melting process at Bundesanstalt für Materialforschung und -prüfung (BAM), Berlin and also contains the terminology of the SciGlass database (The data has become open source since 2019. See: https://github.com/epam/SciGlass).

A practical use case of the ontology is the Semantic Knowledge Base (SKB) developed with Fast Ontodocker (https://git.material-digital.de/ya-fanchen/fast-ontodocker), which covers the entire glass manufacturing process parameters and glass property searching, as well as the integration of SciGlass data.

It is based on the PMD Core Ontology (PMDco) v1 and a migration to the latest PMDco is planned.""" ;

The appearance of the maximum on the dilatometric curve is connected with the parallel influence of sample dilatation with increasing temperature and sample deformation due to the viscous flow. The position of the maximum can correspond approximately to a certain viscosity of the studied glass. Usually this viscosity is assumed to be equal to 10^11 P. However this value depends a great deal on the external load applied to the sample (the greater the load the higher corresponding viscosity), on the area of sample section (the greater the area the lower viscosity), on the value of TEC for the studied substance in its liquid state (the higher TEC the lower viscosity), on the rate of heating and on the previous thermal history of the sample (the higher the heating rate the lower viscosity; the lower the fictive temperature of the substance the lower viscosity). Thus the actual  viscosity  values at dilatometric softening temperatures could differ from the value stated above as greatly as  one order of magnitude.

A deficiency of this approach is the fact that the borderlines of hysteresis loop depend on the precision of measurements of the corresponding property. However, in the most cases, it is not essential to know exact positions of the boundaries of the glass transition regions and the method mentioned above is quite acceptable.

It should be noted that this thermodynamic definition of liquid state does not agree with the most common definitions of liquids as substances, the main characteristic of which is the fluidity. According to the thermodynamic definition a liquid could be thoroughly rigid (for example, after a very long isothermal hold, a glass-forming substance can reach a metastable state at viscosity of 10^15 P or higher).
