It seems that there is an opportunity to add "Glass Transition Temperature" to the ontology. I think this may fit as a Class under "physical descriptor." It would be at the same level as "boiling point descriptor," "freezing point descriptor," and "melting point descriptor." Something like "glass transition descriptor" might be consistent with the naming of the other Classes. The new Class could be further sub-classed into "calorimetry" and "dilatometry."
