The generally accepted temperature for the reduction of cassiterite to tin metal using charcoal seems to be
the higher of the two temperatures.
I suppose the lower temperature might possibly relate to the smelting of combined tin/copper ores in
the production of bronze, but I'm guessing really.

Subject: tin smelting temperature
Two authoritative sources offer quite different temperatures at which
tin metal is released from its oxide
700 degrees C :
J. G. McDonnell, "Pyrotechnology," in D. R. Brothwell and A. M. Pollard,
eds., Handbook of Archaeological Sciences (Chichester: Wiley, 2001), p.
499.
1100 degrees C
R. F. Tylecote, The industrial revolution in metals Institute of
Metals, 1991.p 37
Can these be reconciled or is one wrong ?
