Wearing rubber gloves on I start dripping a little acrylic fluid into the mold
and slush it around. Always work under forced ventilation and keep gloves on the whole time as this can be hazardous to your health .

tandgjut24.JPG (10436 bytes)Gently I sprinkle the acrylic powder down in the teeth mold
. I start with a little transparent powder and continue with a light tooth shade. Then I continue with a little more yellow and last a quite dark one. This is for making the teeth seem like they have a natural shade. Unfortunately it is very hard to get it right the first time, only experience will help you here. .
When the correct amount of acrylic mixture is in the mold
I gently reposition the plaster teeth into the mold
. It is very important to make it fit as snugly as it did when you made the mold
. Putting it back incorrectly will make the teeth to become too thick or get air bubbles.

under light pressure for a couple of minutes.
Place the mold
s into a pressure cooker (3 bar) with hot water for final hardening.

If you don't have a pressure cooker you will have to wait maybe 30-45 minutes.
Hopefully you now can separate the mold
s and take out a good cast.
Sometimes you can make a second casting but often the plaster teeth becomes bad.
