IRON from SAND

From January into the end of May I filmed 6 bloomery smelts at The Crucible in Oakland, California. Iron oxide is extracted from sand and then put into a charcoal burning furnace which has a reduction atmosphere. Here the iron get separated from the oxygen and combines into a bloom – a blob of iron ready for further processing by the blacksmiths. The iron was used in an art piece which will be featured in the next video.
