A first baby hand made of porcelain plaster from a 3D alginate mold.

Wow, I did it! I got a great result the first time. How did I do this? Well, it wasn't that hard!

I was given the tip in advance to read the description carefully. For convenience, I have displayed everything I needed together on a table. The supplies: the 3D-Alginate, Porcelain Plaster, a mixing cup, small whisk, a scale and a mixing spatula.

The description states that you should measure the ratio by weight. So not by eye or in liters. I followed this exactly. 250 grams of 3D-Alginate with 1000 grams of water. I used very cold water, so that the hardening takes a little longer. Mixing the 3D-Alginate with a whisk went very well. There were no lumps anymore.

Now my daughter's hand in it. She didn't like that cold water. Maybe use lukewarm water next time. Then I have to work faster, because then it will harden faster. My daughter moved her hand a lot in the beginning. That was handy, because that way all the air bubbles came out. Eventually the 3D-Alginate became harder and harder and her hand also came to a standstill. It did indeed take about five minutes to harden. I slowly took her hand out. The result was impressive.

Now to make the porcelain plaster. Again measured in proportion in weight and mix. I mixed this with a mixing spatula. Make sure you don't knock in any air bubbles, because you will still see this in the end result. If you mix well, you will get a nice smooth mixture. Okay then, let's pour! Some air can remain in the fingertips. You can prevent this by pouring the porcelain plaster into the mold at an angle and moving it a little. Make sure all the air can escape from your mold. I myself turned the mold at an angle after pouring and tapped it a little against the mixing cup.

The Reveal:

The best part is unpacking the end result. I didn't need the mold anymore, so I just pulled it off the porcelain. I was amazed by the result. What a super nice good print it had become! All wrinkles and nails were very visible! Very happy with the result, I immediately posted this on Facebook at Silicones & More.
