It is the quarter-final and two potters will be sent home.

In the throw down, the potters have just ten minutes at the wheel to throw the widest bowl they can while blindfolded.

For their spot test, they must carve a pattern onto the surface of a Greek urn using the centuries-old technique of sgraffito. Derived from the Italian word for scratched, sgraffito involves etching through a layer of coloured clay to reveal a contrasting colour beneath.

In the main make, the potters must hand coil and decorate four Russian nesting dolls. The top and bottom of each doll must slot together using a flange and gallery connection and the four must stack inside each other seamlessly.

Who will clinch their place in the semi-final and which two potters will be walking the cobbles home? Show less
