Dear V.Zavyalov,
When this paper was written, it was not generally realized how much
phosphorus there was in bloomery iron smelted from high phosphorus ores.
So this paper was an over ingenious explanation of a common phenomena.
There have been a lot of better papers on phosphorus in bloomery iron
more recently. At least one is in the arch-metals bibliography at
http://users.ox.ac.uk/~salter/arch-metals/met-bib-ak.ht
or
http://www.jiscmail.ac.uk/files/ARCH-METALS/met-index.htm
Basically, Thomsens method is not a practical method of producing the
amount of P-iron that is found in migration period artefacts. The
analytical work I have carried out for Brian Gilmour shows that at least
one of the components of the pattern in patern-welded swords is
phorphoritic iron. And to repeat, it is entirely unnecessary as the
experiments of Peter Crew and others have shown.
