in the mid to late 3rd millennium bc the "fast wheel" was developed, which operated on the flywheel principle. it utilised energy stored in the rotating mass of the heavy stone wheel itself to speed the process. this wheel was wound up and charged with energy by kicking, or pushing it around with a stick, providing a centrifugal force. the fast wheel enabled a new process of pottery-making to develop, called "throwing", in which a lump of clay was placed centrally on the wheel and then squeezed, lifted and shaped as the wheel turned. the process tends to leave rings on the inside of the pot and can be used to create thinner-walled pieces and a wider variety of shapes, including stemmed vessels, so wheel-thrown pottery can be distinguished from handmade. potters could now produce many more pots per hour, a first step towards industrialization.

after moulding, the pottery was first fired at a low temperature to produce a porous biscuit body onto which paint could be applied. the colours were then applied, followed by a lead ceramic glaze, a technique known as underglazing. the pottery was then fired again at a low temperature in order to preserve the colour, making the product soft and fragile and contributing to the scarcity of original wemyss. pottery produced by the griselda hill pottery uses a different technique, and is much more robust.
