on the subject .. and everywhere i find something "coal is
now how do i manage the fire in the right way? ..
Assuming you have a coal forge, you want use damp, soft (bituminous)
coal, not hard (anthracite) coal. If you don't have a sprinkler can,
make one, you'll need it. Start by filling the fire pot with several
pieces of wadded up paper, followed by some wood scraps (2" x 4" lumber
work great), followed by a thin covering of damp, green coal. (After
the initial fire, you will use coke in this step).
Mound a good bit of coal around your firepot, keep it damp, you'll use
it later.
Light the paper and turn the air blast on low if you have a blower,
crank the blower slowly if by hand, or pump the billows lightly. When
the fire spreads to the wood, you'll need a bit more air. As the coal
catches fire it will smoke like hell! Add more coal, more air, and make
more smoke. The coal should be flaming now. Add more coal until you
have a mound of flaming, smoking coal in your firepot.
Turn off the air, quit cranking, stop pumping the billows - it's lit.
As the impurities are burned out of the coal in your firepot, coke is
formed (the coal "cokes up"). Coke burns hotter than coal, but it burns
to ash. As a consequence, you must constantly tend the fire by
maintaining a supply of burning coke, coal in the process of forming
coke around the coke, and green coal around the coal in the process of
coking. This is done by constantly moving the green coal from around
your firepot to the edge of the firepot, then to the fire. Use your air
blast to maintain your fire as the work requires.
Managing a coal fire is an art unto itself. I've purposely left out the
tricky stuff and I've failed to mention the dreaded clinker, but this'll
get you started.
Please see and
for much better descriptions of the process.

^^^^^^^^^^^^
Tom's description sounds like it ought to help, but I would like to add one
little thing. In order to picture the process, you have to know that the
damp coal, as it heats up and catches fire, forms a crust--the chunks stick
together. This is going to form an "igloo," with hot burning coal on the
inside, with air flowing through it, and damp coal on the outside, waiting
its turn to get to the inside.
Some good suggestion to which I can add nothing but you might want
to try posting on alt.crafts.blacksmith as it is a much better newsgroup
to ask these sorts of questions.

Sorry I forgot the "ing" on the end rec.crafts.blacksmithing, and
yes it exists as I was reading a post on it today (not all servers carry
all groups). If you still can't find it on your server look it up on Google.
Ken
If you don't have that newsgroup then you may have to use one of the web
based access points for the access to that NG. I do have access to it
myself on my newsgroup server.
