In week five, the six remaining potters head to Stoke on Trent, all striving to win pot of the week. In the throw down, the potters rush to make as many goblets as they can in 15 minutes. Any that fail to meet the judges' exacting standards will be thrown into the bin of doom. Kate Malone chooses the spot test, as the potters must hand coil a jug to look like a piece of fruit. In the main make, the potters must throw two giant vases. For the first time in the competition, they are using one of the most exhilarating techniques in ceramics - pit firing. This ancient method of firing is one of the most unpredictable techniques in ceramics and requires the potters to head to the Staffordshire countryside to camp out overnight. Who will emerge from the camping adventure triumphant? And who will be heading home?
