Plaster is a simple craft material that you can easily make yourself at home. All you need is flour and water, or glue and water if you'd rather not use flour. Once the plaster is ready, you can use it to make plaster casts, plaster molds, and even chalk.

To step

Method 1 of 2: Make plaster from flour

1. Heat 250 ml of water to a temperature of 40 ° C. Use a kettle, stove or microwave to heat the water to the correct temperature.
2. Heat 500-700 ml of water to a temperature of 40 ° C. Use a kettle, stove or microwave to heat the water to the correct temperature.
3. Let the plaster cure for 48-72 hours. Glue-based plaster takes longer to set, so it can take up to three days for the mold or cast to dry completely. Let the plaster dry at room temperature so that it dries evenly and thoroughly.

Tips

• Wear gloves and an apron to prevent your plaster from spilling or splattering on your clothes.
• You can buy ready-to-use gypsum powder from hobby stores and on the Internet. That way you don't have to mix anything yourself.

Warnings

• Do not flush plaster of paris down the sink as this can clog your drain. Instead, let the plaster harden and then dispose of it in the trash.
• Plaster dries quickly, so wash it off quickly if you get it on your skin.
• Do not use a body part as a mold, as it will be very difficult to get the body part out of the cast.

Necessities
