[TheForge] Anvil restoration and firebrick.

[Bruce Freeman]

Rob,

Re: the firebrick.  

Moisture is a problem at high heat.  Spalling can be violent.  Dry the
brick in the sun, then heat them slowly, like in a wood fire.

Salt could be a problem.  For one thing, it will make flames bright
yellow FOREVER.  Salt vapors can also affect refractories.  Pottery is
sometimes given a "salt glaze" in this manner.  So it might be best not
to use these bricks in any critical high temperature use.  I'd say it's
worth giving them a try and finding out.

Hello to all.  I have enjoyed reading the vast array of topics and 
information.  Here's my first posting.
I have a 192# anvil I picked up in NH a few years back.  There are a 
few large chips broken out of the face and a very dull horn.  What is 
the correct way to repair this?
Also, I picked up about a third of a pallet of firebrick from the 
inside of a sunken barge.  They were in salt water for for a long time

but they don't seem to be mushy or tender whey they're dry.  Might 
there be an issue of the residual salt or moisture?
Thanks for the help,
Rob Hill
