Fast setting plaster of Paris based mass, spread on a 100% bleached cotton gauze. The bandage is wound on a plastic core.

Exotherm: Plaster of Paris generates heat during setting reaction which can be felt by the patient. The patient should be instructed to report any pain, numbness, irritation or “burning sensation”. If the patient reports any of the above, remove the cast immediately. Inspect the cast to determine the cause of the above symptoms before recasting. Burn injury may result from improper cast application or failure to observe precautions during and after setting reaction.
