raising

Raising is a metalworking technique used to create hollowware, which are hollow metal utensils and artifacts. This method, dating back to at least the 3rd millennium BC, is commonly applied to malleable metals like silver and copper.1

The process involves shaping a disk of sheet metal into a hollow form using a series of hammer blows that spiral from the center outwards. These blows are applied over a stake or anvil. After the initial shaping, a planishing hammer is used to smooth out the hammer marks, creating a finished surface.1

Other techniques for creating hollowware include joining pieces of sheet metal with rivets or solder, casting, and spinning. Metalwork encompasses a wide range of objects, from simple utensils to decorative and ceremonial items, fashioned from various metals.12
