Anything that is quick, affordable and makes beautiful things is a craft winner for me. But...I often find myself uninspired for something new and different.
What will someone make with
- 3 cups of white glue (PVA)
- 3 cups of cornstarch (Corn flour)
- one tablespoon of white vinegar
- one tablespoon of glycerin (health food or hobby shop), and
- 2 tablespoons of canola oil?
Amazingly simple and a GREAT school holiday project, get the kids into the kitchen to cook up some home made, air dried, porcelain.
Let's make it:
In a mixing bowl (or non-stick pan) mix 3 cups of white glue and 3 cups of cornstarch. Add one tablespoon of white vinegar, one tablespoon of glycerin, 2 tablespoons of canola oil. Blend thoroughly with a wooden spoon. Heat in a microwave oven or in a saucepan on the stove.
For microwave heating: Cook in a microwave-compatible recipient for 2 to 3 minutes on high (for a 800W oven; longer for a less powerful oven). Stop every 30 seconds to mix. During the last 30 seconds, stop every 10 seconds to check the consistency of the mixture. As soon as the dough becomes thick and lumpy (like ricotta cheese), remove from the oven.
Stove top: Cook in a saucepan over low heat for about 15 minutes. Stir with a wooden spoon. As soon as the dough becomes thick and lumpy (like ricotta cheese) and starts to pull away from the side of the pan, remove from heat.
Cooking is the only tricky step to making cold porcelain. You need to cook just long enough to thicken the dough but not too long, otherwise it will be too hard and impossible to work with.
Coat your working surface and your hands with cold cream or hand cream. Knead the dough until it has cooled. It can be quite hot to begin with, so take care. The dough is sticky and lumpy at first, but as you knead it, it becomes smooth and supple. Make a large ball and store it in an airtight container for 24 hours before using it.
This one's a big thumbs up from me. I can feel some air dried porcelain Christmas decorations coming up.
