In the UK, the term refers to a method of testing anvils. Black powder was poured onto the top of the anvil and ignited. If the anvil did not shatter it was deemed safe to use.
Typically, two anvils are used: one as a base (placed upside down), and another one (also known as the “flier”) as the projectile (placed right-side up, atop the base).
Alternatively, a single anvil can be fired from a stone base. The space formed by the anvil’s concave base is filled with black powder (not modern gunpowders, which have much higher energy densities) and a fuse is made to project out. The fuse is lit, and the resulting deflagration (the rapid combustion of the powder rather than detonation) sends the projectile anvil several feet into the air.
An alternative method is to place the bottom anvil upside down, and fill the hardy hole with black powder. A torus or washer, often made from a playing card, is placed over the hole, with a space for a fuse or powder trail. The top anvil is placed upside down, face to face with the bottom anvil.
Anvil firing was once commonly performed in the Southern United States as a substitute for fireworks during celebrations. One such noteworthy celebration was held on the day the state of Texas voted to secede from the Union. On February 23, 1861, Texas Ranger and prominent Union supporter, Thomas Lopton Campbell Jr., was held captive and forced to “fire the anvils” in the streets of Austin.
Although its practice has lessened in recent years, enthusiasts still participate in anvil launching events and competitions. On September 5, 2011, The Science Channel premiered Flying Anvils, a reality television series about anvil firing.
Individuals may be crushed by a falling anvil. The black powder can also prematurely ignite when the top anvil is placed, which can cause black marks on any nearby individuals.
Physics and chemistry
A 21 anvil salute replaced the traditional 21 gun salute on Victoria Day 1860 in New Westminster, British Columbia, after the town’s cannon and status as capital of British Columbia was taken away.
On November 7, 1864 during the Civil War, the commander of the Iowa Home Guard militia in Davis County, Iowa, having no artillery piece at his disposal, ordered a local citizen to fire an anvil in the county seat at Bloomfield to alert militiamen in outlying townships in response to intelligence received of the presence of Confederate bushwhackers in Davis County. This was in response to a report of two suspected Confederate guerrillas at a residence in the neighborhood where they had demanded money and food and had terrorized the occupants, Mr. and Mrs. Gore. The private citizen who carried out the order to fire the anvil was seriously injured.
