Sometimes potassium, sodium and calcium are present too. Clay develops plasticity when wet but becomes hard and brittle when dried. this can be because of the way the water molecules surround the clay particles. Clay minerals are white most of the time but sometimes iron oxide makes it a red or brownish colour. Clay is that the oldest known ceramic material dating back as far as 14,000 BC.
WHAT IS IT USED FOR?
Clay has such a good importance and extensive uses. Here are a number of those uses:
• Modelling - Modelling clay is to be used in art and handicraft. Clay gets modelled into pottery for adornment or to be used. Clay is additionally accustomed make cooking pots, dishware, art objects and even musical instruments.

Energy-efficient as its insulation properties mean reduced energy consumption of clay buildings
Durable artifact that's robust and stable, their lifespan is over 100 years
Natural material so better for the earth
Friendly to the economy as clay building materials are quick to form
Maintenance and repair costs are low for clay materials as they're weatherproof
Clay is aesthetic, it is rough or smooth and a range of colors
There are disadvantages of clay and these are as follows:
Clay is slow warming in spring
Slow draining because it retains moisture
Lots of topsoil gets employed in mass construction of bricks
High demand for these bricks means extensive loss of forests being dug up to search out topsoil needed
With demand so high the value for these is rising at a rapid rate
Digging for clay has resulted in wearing away and damage to vegetation. this is often resulting in serious damage to the environment.
IS IT WORTH IT?
With what proportion damage is occurring to our planet with the very high demand for clay it's not worthwhile anymore. Deforestation may be a very big issue on our planet and with clay meaning trees must be dug up, it’s group action worse. If clay was to induce used on a way smaller scale it should are worthwhile.
