Raising is a
metalworking technique whereby
sheet metal is formed over a stake or other solid object by repeated 'courses' of hammering and
annealing. The sheet metal, held at an angle to the stake, is formed using mechanical advantage by hammering just in front of the contact point. When executed correctly raising allows the smith to efficiently shape the metal without thinning thus avoiding the risk of cracking, a common occurrence with parallel forming processes such as
sinking or stretching. In raising the metal at the edge of the sheet is compressed and thickened as the form is necked in. This technique is an essential part of silversmithing and is used to create seamless vessels such as vases, cups, bowls, carafes, pitchers, euers, etc.
