In 1855, the company used its cupola furnace as a small blast-furnace to smelt some iron ore into pig-iron, which was puddled and then sent to the Sydney works of P. N. Russell &amp; Co., where it was used to make anchors, which with some ore samples and other manufactured items—including razors and a carriage axle—were exhibits at the 1855 Paris Exhibition. This was probably the first time pig-iron had been smelted from Australian iron ore.
