It has scientists baffled. It's a substance that although has only been baked in an oven for less than an hour and doesn't rely on the gargantuan pressures and geological time scales, is harder than diamond.

We were doing stress tests on it on the way to Brownies. A 3 metre throw straight up and down onto concrete didn't even scratch it. A 10 metre height broke a bit off but it retained integrity. It skims across concrete remarkably well and we even got a car to drive over it and it still survived.

A remarkable substance with a number of applications.... none involve edibility alas.
