Plaster of Paris is used for many projects from sculpture to handprint and footprint keepsakes. Plaster of Paris can be pre-purchased from a craft store or mixed by combining plaster, silica, and water. Mixing Plaster of Paris can be messy, so use plenty of newspapers or workcloths spread on the floor or table surface before mixing the ingredients.

Step 1 - Equal Amounts

Pour equal amounts of each ingredient into the plastic mixing bowl. Figure out how much you need for your project, then pour your ingredients into the measuring cup. Ideally, you should have 1/3 of each ingredient to make the Plaster of Paris.

Step 2 - Water

Pour the water into the mixing bowl first. Pour the dry plaster and silicate into the second bowl and mix them well together. Slowly pour the dry ingredients into the water, then mix to make sure the plaster mix is wet.

Step 3 - Mix

Use the wooden spoon to break down lumps and blend the plaster so it has a smooth consistency. Once it is blended, the Plaster of Paris is ready to be used.
