[TheForge] Fwd: bog iron/pig iron to wrought iron

[Daniel Kretchmar]

Thanks Andy!  I notived my dragons breath forge was getting as hot as
it should yesterday and when I pulled the bricks away from the
openning, I noticed a gap between the poured refractory and the
kaowool.  The gap was white hot!  I turned off the forge and I'll
replace the kaowool today. I worked with coal and charcoal for a bit
and refined the wrought a bit more, but I wanted wait for the gas for
before welding.   My welding in the coal forge tends to leave
inclusions.  No problem when making axehead, but not good when making
a knife for the wife! I am going out to work in the shop for most of
the day......HAPPY NEW YEAR!
