Gladstone Pottery Slip House: How To Create Industrial Liquid Clay

Behind every pot lies a process few ever see: the weird science of liquid clay. Join us inside the Slip House at Gladstone Pottery Museum, where clay, bone ash and stone were mixed, sieved, filtered, and pressed to form the essential raw material of Victorian pottery.
Featuring additional footage from Middleport Pottery, this video explores the machines, materials and manpower that powered the Potteries long before anything touched a wheel or mould.
