Replicating body parts in plaster

Step 8 Plaster

Since dermagel degrades relatively quickly, you'll probably want to pour the plaster into your mold as soon as possible.

The plaster I used is measured by weight in a ratio of 45 grams of water for every 100 grams of plaster (however, you are going to want to check the specs on your plaster). Once you have measured out your water and your plaster, mix them together until you have a toothpaste-like consistency.

Pour the plaster into the mold. You may need to use a spoon or wooden stick to scrape the plaster out of your mixing bowl into the mold. Try to fill it as best as possible.

When the plaster is in the mold, give it a couple of gentle taps against the ground to raise possible air bubbles.

Lastly, I added a few L-brackets and screws to the back before it dried completely so that I could suspend it from strings if need be while silicone casting in the next step. It is helpful to have at least three points of contact.

Might as well stick your mold back in the plastic cup to keep its shape while casting it. Your plaster is way too thick, that traps air pockets.
