Other forms: coal scuttles
A coal scuttle is a box or bin that coal is kept in. It's uncommon today, but when homes were often heated with coal fires, the extra coal would be kept in a coal scuttle near the stove.
Long ago, it wasn't unusual to add coal from a coal scuttle to a fire that warmed your home. When trains ran on coal, they needed constant burning fires and a coal scuttle from which stokers could feed them. As coal fuel becomes less common, coal scuttles are also increasingly unusual. The scuttle part of the word comes from the Old English scutel, "dish or platter," from the Latin scutella, "serving platter."
