Sulfur. Vaguely hellish and certainly associated with all things hot and stinky, this powdery element can sometimes be bought in drug stores and is often typo'd as "sulphur". On rare occasion it is found in nature as a translucent yellow crystal but more often as powder stain near volcanoes. It is an essential ingredient in the making of rubber and is infamous for that awful smell of rotten eggs - which is actually the deadly gas hydrogen sulfide!

This dazzlingly yellow element can be described as simultaneously glassy and rocky. It is brittle but when it breaks it crumbles into little pieces that are not sharp and will easily turn to dust in your hands. In this cube a little of it is preserved inside a glass ampule that knocks about in a dull clack - again belying its otherwise handsome glassy looks!
