What Is the Origin of the Saying "A Flash in the Pan"?
Someone described as a flash in pan has made a good early impression but subsequently failed to maintain the same standards. The term derives from the time of early flintlock muskets. When a musketeer pulled the trigger, often the flint would ignite the gunpowder in the lock-pan, causing a flash, but this would fail to set off the main charge. The flash in the pan would look impressive, but it would have no effect, i.e., the musket ball would not be fired.
A Competing Theory
When panning for gold, a miner would often see a glint among the sediment he was filtering in the bottom of his pan. The miner would hope this was a piece of gold, but all too often it turned out to be nothing – just a flash in the pan.
