Answer 15

Precautions You Should Read Before Starting

1. Avoid breathing the dust. Those minute particles of Plaster of Paris dust is not something you want to be breathing in which is why it's recommended to make cast in a well ventilated area and wear a face mask.

2. Do not pour leftover liquid Plaster of Paris or the dust down the sink, toilet, or bathtub. This quick drying cement can clog your pipes

3. Use flexible containers to mix the plaster. Metal buckets or your mom's mixing bowls will not work, which means a lot of outdoor scraping and scrubbing to get these containers clean. Containers that work the best for mixing and removable of the dry plaster are ice cream buckets, yogurt containers, or a plastic mop bucket. With a flexible bucket, the plaster can be allowed to dry completely then turned over and "popped" out for quick clean-up.
