 Ironsand is found extensively around the US, especially in the area of New York, Southern California, New England, and the Great Lakes, where it is often mixed with a feldspar sand and sometimes bright grains of garnet.The magnetite from these areas often contains high amounts of chromium and titanium.In the 19th century ironsand was sometimes used as blotter sand for concrete and masonry work, or more rarely as raw material for steel production; one blacksmith in Connecticut used it for making bar stock.
