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 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 is a plaster technician?
A plaster technician is a professional trained in applying plaster casts to immobilize and support injured bones or joints. They work closely with healthcare providers to create custom casts tailored to the patient's specific needs for optimal healing.
What is plaster gauze?
Plaster gauze is a material made of gauze fabric impregnated with plaster of Paris. It is commonly used in medical settings to create casts for broken bones, as well as in art and crafts for creating sculptural forms. The plaster hardens when wet, making it a versatile and easy-to-use material for various applications.
Where is plaster found?
Plaster is commonly found in construction materials, such as plasterboards and plaster mixes used for walls and ceilings. It can also be found in art and sculpture materials for creating molds and casts. Natural gypsum, a mineral used to make plaster, is found in abundance in countries like the United States, China, and Iran.
Why did casts form in Pompeii?
Bodies where buried under volcanic ash. The bodies themselves decayed but left cavities that preseved their dying poses. Archaeologists later poured plaster into these cavities to form casts of the people.

What are molds and casts preserved by?
Molds and casts are preserved by a solidifying. Wet plaster or other materials dry or cure until solid and hardened.
What is used to make a cast?
A cast is typically made from materials like plaster or fiberglass. Plaster casts are made by soaking gauze in a plaster mixture, while fiberglass casts use a resin that hardens when exposed to air. Both materials provide support and immobilization for broken bones or injured limbs during the healing process.
How are casts and splints used for immobilization?
Casts are applied by a physician, a nurse, or an assistant. They are custom-made to fit each person, and are usually made of plaster or fiberglass. Fiberglass weighs less than plaster, is more durable, and allows the skin more adequate airflow.

How were the casts made of the bodies from Pompeii?
The bodies decomposing left a small cavity surrounding the remains. The ash hardened leaving a mold of the person containing just the bones. They located the cavity, drilled a small hole, filled the hole with plaster, then removed the plaster cast containing the bones from the ash.
