Substances that react below a given temperature

Some substances spontaneously combine, ionize, polymerize, or otherwise react to form a distinct chemical substance when they fall below some temperature. For example, disulfur (Q5283603) forms octasulfur (Q7076759), white tin (Q7995705) forms gray tin (Q81885483), and molecular dichlorine hexoxide (Q115869956) forms dichlorine hexoxide (Q1091519). What property should be used to specify that temperature? 73.223.72.200 22:27, 26 December 2022 (UTC)

Probably the same but with some qualificator. --Infovarius (talk) 22:31, 27 December 2022 (UTC)

As above, but proper qualifier should be created for such situations and some example shown in the documentation of this property. Wostr (talk) 19:49, 28 December 2022 (UTC)
