chalkdust
Blackboard eraser aftermath
Chalkdust is the fine powder that accumulates when chalk is used on a blackboard.
It settles on ledges, erasers, and the clothes of anyone who writes extensively: The teacher's sleeves were covered in chalkdust.
The word evokes traditional classrooms before whiteboards and digital displays.
