Properties of sand, clay, granite, limestone.

The property of sand is very simple – flowability, firstly. The sand is not pouring, but it is pouring. In theory, the sand seems to flow, overflows. This impression is created by its fine texture. Sand can be spilled, but not spilled. Dryness is another property of sand. Basically, the sand is dry, but it is possible that it is wet. Absorption capacity is another property of sand, which means its ability to absorb any liquid – water, oil. Excellent throughput. Whatever layer of sand is, it will still let the water through. Unless there will be too little water and it will not flow further. And also, the sand is easily drained – dries up. Clay is viscous, dense, plastic, easily wetted. You can sculpt whatever your heart desires from it. Clay cannot be drunk or eaten, and when stirred in water, the water becomes cloudy. Granite is very hard and durable. Limestone is a rather soft natural material. And when it hits something or something, it can crumble. It dissolves in water, although not completely, and serves as a good building material.
