    Heat 1 cup (240 ml) to 100 °F (38 °C). Warm water works best to help speed up the process. Use either a microwave or a stove to heat the water to the correct temperature.[1] X Research source
    Combine the water with 2 cups (256 g) of flour in a mixing bowl. Pour the water over the flour as evenly as you can. Once all the water is added, start stirring the mix with a spoon or spatula.[2] X Research source If you’re worried about dried plaster sticking to your utensils, use a disposable plastic spoon.
    Stir the mixture with a spatula until there are no lumps. The consistency should be a thick white paste when you’re finished. In the end, the plaster should be thick, but not difficult to stir. If it seems too thick, add more water. If it is too runny, add more flour until it thickens.
    Work with the plaster within 10 minutes. You’ll notice the plaster mixture will start to solidify as you work with it. Pour the mixture into your molds as soon as you’ve finished stirring it for the best results.
    Let the plaster set for 48 hours. The plaster may seem to dry within 24 hours, but it will not be completely set through. Allow it to sit at room temperature for 2-3 days to dry.[3] X Research source
