Allotropy: Why Winter Spells Trouble for the Tin Man

Tin is a commonplace metal that’s used industrially in a thousand different ways. From the solder that holds your computer’s motherboard together to the PVC plumbing under your sink, tin compounds are everywhere.

At room temperature, tin exists in its “beta” form.
