Coal in Irricana

Won't be more than a scoop shovel full. Coal is basically same as rock or gravel approx.. 26-2800 lbs. per cu yd. Weigh a chunk of concrete patio block or garden stone etc for a good comparison.

What is the choice coal for forging & such, bituminous?
Ya 25 pounds would be less than half a cubic foot by volume

As the process continues, the coal becomes dark and hard and is classified as bituminous, which ignites easily and burns for a long time (density 42–57 lb/ft3 or 673–913 kg/m3). Anthracite is the final maturation, a coal that's very hard and shiny (density 50–58 lb/ft3 or 800–929 kg/m3).
