An ashpan is a metal container that collects the ash and small pieces of coal underneath a fireplace or stove. However, there are several other words that can be used to describe an ashpan. One such word is "ashes bucket," which is similar in function and can be made of metal or fireproof ceramic. Another synonym is "ash box," which is a larger container designed to hold larger amounts of ash. A "coal bucket," on the other hand, is designed to hold coal but can also be used to collect ashes. Lastly, a "firebox" is a compartment within a fireplace or stove that contains the fire and collects the ash.
