It is easy to make plaster of Paris at home.If you don't want to handle flour, glue and water are all you need.You can use it to make plaster casts, molds, or even chalk after you've made it.
Step 1: It takes 1 cup to warm up to 100 F.
Warm water can help speed up the process.To heat the water to the correct temperature, use a microwave or stove.
Step 2: The water and flour should be put in a mixing bowl.
You can evenly pour the water over the flour.When all the water is added, start stirring the mix with a spoon or spatula.Use a disposable plastic spoon if you're worried about dried plaster sticking to your utensils.
Step 3: The mixture can be stirred with a spatula.
The consistency should be a white paste.The plaster should be thick and easy to stir.Add more water if it appears too thick.Add more flour until it becomes thick.
Step 4: The plaster needs to be worked on within 10 minutes.
As you work with the plaster mixture, it will solidify.As soon as you have finished stirring the mixture, put it into your molds.
Step 5: The plaster should be set for 48 hours.
The plaster won't be completely set through in 24 hours.Allow it to sit at room temperature for a few days to dry.
Step 6: To get to 100 F, you need 2 to 3 cups of water.
You can heat the water with a microwave or stove.
Step 7: Take 1 cup of water and 2 cups of school glue.
Put the water and glue into a mixing bowl and stir them together with a spatula.When the plaster has a soupy consistency, add a little water at a time.
Step 8: The plaster needs to be worked with within 15 minutes.
Making plaster with glue will give it a slightly longer drying time, but you should still work with it as soon as you finish mixing it.To make the shape you want, pour it into the molds.
Step 9: The plaster should be set for 72 hours.
It may take up to 3 days for the plaster cast to completely dry because plaster with glue takes longer to cure.It should be kept at room temperature for a thorough dry.
