The setting of plaster refers to the process by which the plaster compound changes from a liquid or semi-liquid state to a solid state. This process involves the hydration of the plaster particles, leading to the formation of a solid mass that can be shaped and used for various applications like mold-making, casting, or wall finishing. The setting time of plaster can be controlled by adjusting factors such as water content, temperature, and additives.

What happens when you mix dirty water with plaster?
When dirty water is mixed with plaster, it can affect the setting time and consistency of the plaster. The impurities in the dirty water can weaken the plaster mixture and result in a lower quality finish. It is best to use clean water to ensure the plaster sets properly and maintains its strength.
What bonds are broken and remoulded during setting?
During setting of materials like concrete or plaster, the bonds that are broken are water molecules, which are used in the hydration process to form new chemical bonds. These new bonds include the formation of calcium silicate hydrate (C-S-H) gel in concrete and gypsum crystals in plaster, which give the material its strength and durability.
What will happen if heating is not controlled while preparing plaster of Paris?
It may be noted that the temperature should be controlled carefully. It should not be allowed to rise above 152°C (425K) because, if whole of the water is lost then anhydrous calcium sulphate is produced, which is called dead burnt plaster and it does not have the properties of Plaster of Paris.
What retardents are to slow the hardening of plaster of Paris?
Retardants such as borax, lime, or vinegar can be used to slow down the hardening process of plaster of Paris by extending the working time before it sets. These retardants help to control the setting time and allow for more flexibility in working with the material.
What element are in plaster casts?
Plaster casts are primarily made from gypsum, which is composed of calcium sulfate dihydrate (CaSO₄·2H₂O). When heated, gypsum loses water and becomes calcium sulfate hemihydrate (CaSO₄·0.5H₂O), commonly known as plaster of Paris. Other components may include additives for various properties, such as setting time or strength, but the main elements involved are calcium, sulfur, and oxygen.
What is used to slow down the setting processof casting plaster?
A retarder is typically added to the plaster mixture to slow down the setting process. This allows for more time to pour and work with the plaster before it hardens.
