glass transition temperature[edit]

Originally proposed at Wikidata:Property proposal/Natural science

Descriptiontransition in amorphous materials from a hard and relatively brittle "glassy" state into a viscous or rubbery state as the temperature is increased
Representsglass transition (Q825643)

  • Symbol support vote.svg Support It tends to be a range, you're ok with using the built-in quantity +- feature for this? ArthurPSmith (talk) 17:33, 8 August 2018 (UTC)
Many material properties are a range so that we will have to deal with it. It would be simpler if we had the choice to write it 20~25 rather than 22.5±2.5. A potential improvement for the Quantity datatype ? --Thibdx (talk) 09:35, 9 August 2018 (UTC)
