It is very important to measure the hardness of the plastic, without knowing the hardness level of the material you can’t assure its quality if you want to meet the expectations of your customers then the material quality should be very high.

Rocks are made up of one or more than one minerals. These minerals are inorganic, solid and pure materials that are found in the crust of the Earth and are composed of one or more elements.

There are several tests used to determine the hardness of materials and to determine the size of the impression left by the test and hardness. One of the renowned tests is named as superficial hardness test or superficial Rockwell hardness test.

The hardness test gives you the chance you determine the properties of the specific material. The physical properties include the three different things such as strength, ductility, and resistance.

Vickers hardness testing is a multifaceted testing method that can be used for both micro and macro hardness testing. Vickers hardness test was developed by George E. Sandland and Robert L. Smith in 1921 as an alternative to the Brinell method for measuring material hardness.
Quartz is considered one of the most abundant minerals found in the Earth crust that comes second in abundance after feldspar. The term ‘Quartz’ is derived from the Polish words “Twardy” and “kwardy” meaning ‘hard’.
Copper plays an important role in the life of human beings. From the delivering of electricity to the supply of water, copper made all things possible. It allows the electric current to passes through it with the same voltages; it is the good conductor of electricity. The copper is used in the electric appliances, almost every high-quality motors have the copper wires in them. In the past, the cutlery item is made from the copper with are a good conductor of the heat and cold. Copper itself is soft in nature but when you mix it with any other metal it becomes hard.
The ability of any certain object or substance to resist indentation when a force is applied to it is known as hardness. An object’s hardness should be classified as a feature or a characteristic rather than one of its properties and the hardness is generally measured by calculating the permanent area of the indentation caused by a fixed load.
But what does hardness actually mean? Despite popular conception, or rather misconception, it certainly does not indicate toughness of a material or substance. Diamond, which is the hardest, would most certainly crack if hit with a hammer. Steel, on the other hand, would not.
