In the kitchen ...

Krystal in the kitchen There are minerals in your kitchen.

What do you find in your kitchen cupboards and drawers? Plates, glasses, and mugs; knives, forks and spoons. They are all made from minerals.

Can you think of any other minerals hiding in your kitchen?

Scroll down and find out more about the minerals used in cooking.

Cutlery
Knives, forks and spoons are usually made from stainless steel. Stainless steel is made by mixing molten iron with another metal called chromium which stops the steel from rusting. Iron and chromium both come from minerals.

Think about the properties of stainless steel:

Strong
Rigid
Hard
Does not rust

You can see why we make cutlery from stainless steel.

Crockery
Plates, bowls, cups, saucers and mugs are made from clay minerals. You may have used clay at school to make a pot or bowl. Once it has been fired clay is fairly hardwearing. It is also a good thermal insulator - so it keeps your dinner nice and warm!

Think about the properties of clay:

Easy to shape when wet
Strong and rigid when fired
Impermeable when fired
A thermal insulator

You can see why we make crockery from clay.

Drinking glasses
Most people have seen a quartz crystal, but did you know that quartz is the major ingredient of glass? Pure quartz sand is melted down, and mixed with other ingredients to make glasses of different sizes, shapes and colours.

Think about the properties of quartz:

Hard
Rigid
Impermeable
Transparent (see-through)

You can see why we make glass from quartz.

Pots and pans
Pots and pans are made from metal - stainless steel, cast iron, copper or aluminium. All of these come from minerals. But did you know that the non-stick coating you find on many pans is also made from a mineral?

Fluorine is used to make non-stick Teflon ® and comes from the mineral fluorite. The same coating can even be found on your winter coat to keep it clean and waterproof.

Think about the properties of pots and pans:

Strong
Impermeable
Do not rust
Conduct heat

Cans and tins
Cans for fizzy drinks are made of aluminium, which comes from a material called bauxite. It is light, easily shaped, and does not rust.

Tin cans - the cans you get your baked beans in - are actually made of steel. They are coated in tin, a metal which stops the steel from rusting. Cassiterite is the only ore of tin.

Think about the properties of these types of cans:

Impermeable
Do not rust
Compressible (you can squash them)

Cleaning products
Some of the cleaning products in the kitchen are also made from minerals. Hob cleaners contain clay minerals and a chalky material called calcium carbonate.

When mixed with detergents and other chemicals, their grainy texture can clean away the toughest grime.

Think about the properties of clay minerals:

Break up easily (to mix with a liquid)
Are grainy and abrasive

You can see why we make cleaners from clay minerals.
