The Many Uses Of Limestone and Lime

In Victorian days ordinary limestone was used mainly as a building material instead of bricks and also used as a flux in blast furnaces to remove the impurities from the iron.

When it was burnt and became quicklime it was then used as follows:

 - a fertiliser for acidic soil

 - to make lime cement

 - to make whitewash, a form of white paint

 - to destroy the bodies of infected animals or even people!

Lime is now used in the manufacture of hundreds of different products. Here are just a few:

Suggested Activities:

1) Find a photo of a room at home or school. It could be from a magazine, from the internet or you could even draw a picture. Use arrows and labels to identify all the objects which have been manufactured using limestone.

2) Write a five line account of what you did before you came to school. Mention as many different ways in which you used limestone and underline each word in blue.

Eg. I washed my hands in the sink then sat down to eat a boiled egg.
