To ethe limitations of differential thermal analysis (DTA) and direct casting experimentation in
the measurementand understanding of the solidification phenomenaof mold slags, the double and single
hot thermocouple techniques (DHTTand SHTT)for the direct observation and measurementof mold slag
crystallization were developed. These methodsenable the solidification and melting process of transparent
slags '"in
to be observed situ" under conditions where the t
