Some Plaster of Paris Creations
Creating plaster of Paris can be very fun and rewarding. Follow these simple steps to create a mold from plaster of Paris.
Ingredients You'll Need
Gather your materials: You'll need plaster powder, water, a bowl and spoon, plastic molds and a craft or small knife.
Make Plaster
Place the plaster powder into a bowl or container. Follow the directions on the powder's box to determine how much water should be added, but as a rule, for every two cups of plaster, add one cup of water. Once the water is added, slowly and thoroughly stir until it is well mixed. The more water, the longer it will take for the plaster to dry, but it will also be less heavy than plaster that is made with a thicker consistency.
Using Plastic Molds
Spread a barrier on the mold so the plaster of Paris doesn''t stick to it after you pour it in. Petroleum jelly is a suitable option for a barrier. Spoon the plaster into the molds that you would like to make. You can get plastic molds of animals, plants or almost anything you desire at an arts-and-crafts store. Plaster can take from 20 minutes to hours for the plaster to dry, depending on the size of the mold, but you can touch the back of the plaster to see if it's hard or not.
Let it Dry
Take the plaster out of the molds carefully so that they are not damaged. If you notice any inconsistencies or imperfections you can use a small craft knife to slowly scrape off any plaster.
After you are satisfied you can lay them out on a plate or rack overnight to harden.
Creating Plaster Molds
If you can't find any molds that you like, you can also make some out of plaster of paris. All you have to do is mix the plaster as described in Step 2 and pour it into a plastic bowl. Once you've decided on an object whose shape you like, you can carefully put it into the plaster mix. Make sure to cover all the object's sides with the plaster mix.
Using Plaster Molds
Once the mold is completely dry, you are now ready to use it.
