WebTwo allotropes of tin occur near room temperature. The first form of tin is called gray tin and is stable at temperatures below 13.2°C (55.76°F). There are few, if any, uses for gray tin. At temperatures above 13.2°C, gray tin slowly turns into tin's second form, white tin. White tin is the normal form of the metal and has many uses.
