http://en.wikipedia.org/wiki/Tin_pest

" At 13.2 degrees Celsius (about 56 degrees Fahrenheit) and below, pure tin
transforms from the (silvery, ductile) allotrope of beta-modification white tin
to brittle, alpha-modification grey tin. Eventually it decomposes into powder,
hence the name tin pest."
