At last! A tried and tested recipe for air-dried porcelain has hit the Havven head quarters. The ideas are coming thick and fast with what we are going to do with our first batch of porcelain: tiny expresso mugs, ring dishes, gift tags, name plates… (inhale) Don’t you just wish you could just drink coffee, and make things all day?
What you will need::
- 3 cups of white glue (PVA)
- 3 cups of cornstarch (corn flour)
- one tablespoon of white vinegar
- one tablespoon of glycerin (supermarket or hobby shop)
- 2 tablespoons of canola oil
Let’s make Air-dried Porcelain:
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 the microwave for 2 to 3 minutes on high (based on a 800W oven). Stopping 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 (think 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 (think again, ricotta cheese) and starts to pull away from the side of the pan, remove from heat.
Cooking is the only tricky step to making the air-dried 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 hand cream to act as a barrier. 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.
