[TheForge] Free Firebrick, Portland, OR area

[David E. Smucker]

Do you know if it came from the smelting pots themselves?  If so they may
have a rather high contamination with fluorides from the smelting process
itself.  I would not use such firebrick myself.  If the firebrick is new, it
should be OK to use or if the brick came from metal transfer pots that
should not be a problem.  I am a retired mechanical engineer who spent 32
years with ALCOA.  (Aluminum Co. of America).  "Spent pot lining" as we
called them are considered a hazardous waste.  This is because of the
fluoride salts that become part of the lining in use.  We (Alcoa) would not
let spent pot lining out of our control.  I don't know what Reynolds used to
do.  (Reynolds is now owned by ALCOA).  On the other had we would scrap used
firebrick from transfer pots, and melting furnaces with no issue.  Surplus
new brick would sold / scraped depending on how much someone wanted to get
rid of.
