What happens when plaster of Paris is exposed to air?
When plaster of Paris is exposed to air, it undergoes hydration, which means it reacts with water vapor in the air to form a solid material. This process causes the plaster to harden and set into a rigid structure.
What makes play doh harden?

What happens in a plaster room?
In a plaster room, medical professionals typically apply plaster casts to immobilize and support bones or joints that have been injured. This process involves wrapping wet plaster strips around the affected area and allowing them to harden, creating a protective shell to promote healing. The plaster room may also be used for removing casts once they are no longer needed or for making modifications to existing casts.

What happens of you put plaster on a water balloon?
If plaster is put on a water balloon, the plaster will absorb the water content from the balloon, causing it to harden. This can result in the balloon deflating as its water content is absorbed by the plaster, leaving behind a hardened plaster shell in the shape of the balloon.
Which mineral makes plaster harden?
First you need to recognize that "plaster" is not a singularly defined material; it is a family of quite different materials that harden by different mechanisms. The three most common plasters are (1) Plaster of Paris, (2) Lime Plaster, and (3) Cement Plaster.(1) Plaster of Paris is CaSO4.H2O, a partially-dehydrated form of Gypsum, which is a hydrated Calcium Sulfate crystal CaSO4.2H2O. When Plaster of Paris is mixed with water, it re-hydrates and turns back into Gypsum, which then hardens into a material similar to mortar or concrete but considerably softer. Water is the material that makes Plaster of Paris harden.(2) Limestone When exposed to atmosphere the Calcium hydroxide turns back to limestone, causing the plaster to set.(3) Cement Plaster is a mixture of Portland Cement powder, sand or other filler, water, and either Plaster of Paris or Lime Plaster. Due to the great variety of minerals that makeup Portland Cement and Cement Plaster, the hardening is a complex process that cannot be ascribed to the action of any one of the ingredients.
Does plaster of Paris go bad over time?
