Step 3: Pouring the Latex
After the Hydrocal was set, the clay was removed and cleaned out from the mold. There had been one air bubble right near the eye, which left something like a mole on the eyelid. I liked it, so I left it! If there are corrections to be made, it's easy to just fill in holes the more plaster, or carve away extra build up with a sculpting tool.
I used very basic mask latex for the casting, which is super easy to use. I poured the latex into the mold, sloshed it around to make sure that to get it in all the tiny spaces, let it sit for a minute, and poured out the excess. Then I tapped the mold a whole bunch to get out any air bubbled (believe me, there will be air bubbles - esp around the nose!
After this layer of latex was set, I repeated the process several times until the mask was as thick as I wanted it to be.
When the final layer of latex was set, I removed it from the mold and dusted it with cornstarch to keep it from sticking to itselt. Traditionally, talcum powder is used, but it's so bad for your lungs, why risk it!
Next I cut away the excess latex and hand sewed it to a wool hood so it would fit over my entire head. Trying it on was like looking into a creepy future-mirror. Note to self: moisturize daily!
