Raimey,
I will have to think a bit about how best to present some useful informations in English. There is MASSIVE amount of stuff in Swedish and this is not techincal area where I am very compentent translator.
In brief summary, I can say that Valloner are an important part of total "equation", but, so is chemical composition of Dannemore ore and simple fact that they used tree charcoal instead of coal coke (lots of trees in Sweden, but not much coal). One must also mention important roll of leading Valloner, DeGeer's extended family especially, that had extensive business connections in Europe and England, as well as huge financial reserves (financiers to Swedish kings). Consider that priveliged relationship of DeGeer lead to Valloner having major roll in processing Dannemora ore, that DeGeer and other Valloner had excellent business connections with Sheiffield, that järnbruk (iron processors) were a major engine in Swedish foreign exchange economics and world power status (long ago - 1600s, 1700s, into 1800s). One järnbruk, Leufsta, was ordered to become showplace where Swedish king could bring foreigners to impress them.
Maybe if you say what you are most interested in, I can find something specific and small enough that translation will not be big job.
Niklas
