Facts About Gypsum or Plaster of Paris (Calcium Sulfate)

Used since ancient times, plaster of paris is so called because gypsum was early used near Paris to make plaster and cement. Plaster of paris is also used to precast and hold parts of ornamental plasterwork placed on ceilings and cornices and is used in Medicine. But nowadays, it has been used as a coagulant or precipitating agent in making "Taho" and "Tofu".

When mixed with water plaster hardens and becomes hot (temp. 150 degrees). Do not submerge any body parts into the plaster as severe burns may result.

Call a physician immediate if ingested. Children should not use this product except under adult supervision.

3. The plaster is likely POISONOUS. Good thing kids NEVER eat stuff they play with…
