Organized in 1978, the Appalachian Blacksmiths Association is an affiliate of ABANA. We represent blacksmiths, bladesmiths, and farriers in West Virginia and its surrounding states of Pennsylvania, Ohio, Maryland, Virginia, and Kentucky. 

We publish a quarterly newsletter which keeps our membership up to date on events. The newsletter also features many metalworking tips.

COAL

TESTS

coal miner with canary

Before underground coal mines were ventilated, the miners took canaries into the mine. If the bird died, the air was toxic and the miners retreated.  Methane gas (explosive in certain concentrations) seeping from the coal seam is still a danger in modern coal mines.  From State of WV Mine Safety archives.

"Washed" means coal has gone through a preparation plant to separate coal from binder slate and other impurities.

"Free Swelling Index" and "Coke Button" are measures of structural strength of coal when it cokes.
