What is Iron stone? What is uses of iron stone?
Ironstone is a form of sedimentary rock that has a wide variety of commercial and
consumer uses. Sedimentary rocks are formed by the gradual accumulation of sand
or other small particles over time. Eventually the compacted particles are turned to
stone by a combination of heat and pressure. In the case of ironstone, the particles
are iron, clay or sand. Ironstone is dark gray when first mined, but over time turns
brown because of oxidation.
Iron Extraction
The primary industrial use of ironstone is in the extraction of iron. This is because
about half the mass of ironstone is accounted for by iron atoms. The extraction
process involves grinding down the ironstone and placing it in a blast furnace.
Uses of Iron stone
Ceramics
Ironstone is used as part of ceramics, including the eponymous "ironstone china."
Ironstone china was introduced in the early 19th century by potters keen to find a
cheaper substitute for porcelain, which could only be manufactured out of rare
clays.

Building Material
Because of its aesthetic properties, ironstone has been used in the construction of
buildings for a long time. Many churches in Leicestershire, England, are built of
ironstone.
Landscaping
Ironstone is often used by landscapers in the construction of rockeries and water
features because of its unique ruddy-brown coloring. Large amounts of ironstone
are quarried for this purpose in Oxfordshire, England, among other locations.
