Have you ever wanted to cast a part of your ear, but never known how? With this tutorial, you will learn all of the tips and tricks in order to create a successful and detailed casting. Let’s get started! First things first, make sure you clear off your surroundings to avoid any mess! Layout a plastic tarp and cover the subject in plastic, so no alginate or plaster is able to get on their clothes. To avoid getting alginate in the subject’s hair, place a swim cap over the subject’s head and tuck all of their hair under the cap, leaving the ear which will be casted out of the swim cap. Make sure the subject is in a position they will be comfortable holding.It is recommended that the subject lies down on their side, exposing their ear to the ceiling. Once the subject is in position, place a bottomless cup around the subject’s ear and place cotton into the subject’s ear so that no alginate goes into their ear canal. Incase the subject becomes bored or uncomfortable, it may be nice to have someone sit by their side during the process.When you are ready to begin casting, begin creating your alginate solution. First, obtain a mask and cover your mouth (you don’t want to get any dust in your mouth!) Gather a bucket and mix one part lukewarm water with one part alginate into until the solution is fully mixed. Once the solution is mixed, make sure to act quickly! The alginates hardens fast.
Carefully pour the alginate into the cup and onto the person’s ear. Have someone hold the cup upright, allowing the cup to stay still and prevent an unsuccessful casting. Let the alginate harden for 8 minutes (you might need to take more time) depending on the hardness of the alginate.
After you feel alginate is hardened, remove the cup and the alginate from the subject’s ear. There might be some alginate left over on the subject’s hair, but a little water should quickly solve that problem. If you have excess alginate on your casting, carefully rip around the sides in order to show a perfect representation of your ear.
Then, take a new bucket and mix the plaster solution with 45:100 plaster and lukewarm water.
When the plaster solution is thoroughly mixed, carefully pour the plaster into the cup containing the alginate mold and agitate the mold until there are no more air bubbles in the plaster. After enough plaster is into the cup, wait for the plaster to harden (this may take about 24 hours). After waiting for about a day, retrieve your casted ear and begin to remove the hardened alginate from the plaster. Slowly and carefully remove the alginate from the plaster with your hands. Congrats! You are finished. Enjoy your casted ear!
Tips for the subject: Relax and remain calm! Make sure to wear comfortable clothing. Don’t be alarmed by the alginate and stay at still as you possibly can while the alginate is in your ear!
