The glass transition is a second order phase transition. For materials that have a glass transition temperature, below it they are hard and brittle and above it they are softer and "rubbery".
Tm is temperature of melting. Tg is glass transition temperature.
You have to boil and heat water and add sodium acetate (a powder easy to find online), and mix it until it is fully dissolved. Then pour the water in a glass and put the glass in the fridge. After 2 hours, the liquid is ready. You pour the liquid into and kind of place, or leave it in the glass. Then, you put a tiny little part in your finger of sodium acetate, and touch the liquid. It will then turn into dry ice.
Temperature affects glass like it does anything else. If the temperature of glass gets high enough, it will melt. There is not a typical melting point for glass, as it depends on the composition.
Cobalt
The bonding materials for glass layers in laminated glass are polyvinyl butyral or ethylene vinyl acetate.
The glass temperature transition is for glass, polymers, etc. (amorphous or semicrystalline materials), but not for leather.

Tm is temperature of melting. Tg is glass transition temperature.
The -125 degrees indicate the transition temperature of Polyethylene from glass.
cooling rate
Depending on the polymerization, the glass transition temperature will be between -13 C and -8 C; that's 8.6 F to 17.6 F.
Around 70 degrees Celsius.
Polybutadiene rubber.(PBR)
-76 degree Centigrade.
Glass transition temperature of EVA depends significantly on the VA content. Decreasing VA contents result in a lower Tg. Usually Tg is about -20ºC, for higher VA content is -15ºC, for lower VA content is -40ºC.
