The Great Pottery Throw Down - Season 2 Episode 6 -

The potters face the quarter-final and a main make in which they have to hand coil and decorate four Russian nesting dolls. It's arguably the trickiest test so far as not only must the four stack inside each other seamlessly, but the top and bottom of each one must also slot together using a flange and gallery connection. For the spot test, the amateurs carve a pattern onto the surface of a Greek urn using a centuries-old technique, and in the throw-down they have just 10 minutes to create the widest bowl they can while blindfolded.
