[TheForge] Coal Forges - lets try this again

[Mike Linn]

Pot failure is mainly caused by improper fire management. Instructors 
want to get people hooked on blacksmithing by having them hit hot 
iron, very few take the time to teach proper fire control and management.

The wearing out of fire pots comes from letting the fire get to the 
pot.. ie.. letting the fire burn down till there is insufficient fuel 
left..or letting the fire burn out to the walls of the pot. There 
should always be green coal  in contact with the pot.. you feed the 
fire from the sides ... in. In other words, push the coal down the 
inside of the wall..  forcing the coke to the center.. then as the 
green coal cokes.. it is pushed inwards by new coal..

Water is used to help keep the fire from spreading throughout the 
pot..  I have seen pots cracked by water but that was after the fire 
got out of hand and TOO much water was used. I use either a sprinkle 
cup or a rag on the end of a rod to control flames.. think of it like 
knocking back the hot spots when BBQing..

Ive actually forged all day, and when I took the fire apart that 
night, Ive found bits of un burned newspaper from when I started the 
fire that morning.

Lastly.. my fire pot IS made of stainless.. its 3/8" plate and 
actually is a pot within a pot, which actually air cools the pot as 
the air is blown in. Its about 10 years old now and has barely 
changed color. However a good cast iron firepot should last several 
lifetimes if proper fire management is practiced.
