<DIV><FONT face=Arial size=2>I have long been sceptical about the amount of
tin that may be lost "up the chimney" during the meting process. I could not
see how something costing several thousands pounds per ton could be "lost"
without some effort being made to prevent or recover it. In 1976, I wrote to
the Tin Research Institute and asked their opinion. I quote the following from
their reply:</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>"The molten metal is usually tapped from the
furnace into a ladle at approx 1100 degrees C, and poured at a slightly lower
temperature. Since the boiling point of tin is 2267 degrees, any loss of tin
ocurring will be the result of oxidation rather than volatilisation. The rate
of oxidation of the tin will depend on the furnace conditions, but if a
charcoal cover on the melt is used, any tin oxide present will be reduced to
tin, avoiding any tin losses."</FONT></DIV>

Back in the days of itinerant bellfounders, bell casting was done on

So <BR>> all available metal from old bells was re-used in the process,
as a <BR>> simple matter of economy. That's where the term "recast" comes

new metal!<BR><BR>R<BR><BR></P></DIV><!--End group email --></BLOCKQUOTE>
