Hurstwic: Iron Production in the Viking Age

The iron ore shown to the right was excavated from Skógar, a Vikingage ironmaking site in Iceland. The larger piece is about 2cm (less than 1in) in the long dimension. Sometime about 1000 years ago, someone gathered this iron ore, processed it, transported it to the iron smelting site, but for unknown reasons, never used it in a smelt.

Different Types of Iron Ore

Iron formation consists of iron ore such as siderite, magnetite, and hematite, with silica in the form of chert, jasper, etc., generally in bands, but sometimes not distinctly so. The bands of iron ore are at times highgrade, but are often mixed with a good deal of silica, the whole making an ore too lean for use without concentration.
