	Starting from the centre then working outwards, it may initially take two or three blows with the hammer to set the metal down on to the '''[[:Category:Stakes\|Raising Stake]]''' after which the work is rotated as the metal is struck by subsequent hammer blows until a full circle is completed.

It is important that the metal is thoroughly cleaned before '''[[Planishing]]''' ''(e.g. by '''[[Pickling]]''' and/or scouring)'' to avoid any grit, oxides or other contaminants being hammered into the surface.

=====Description=====

[https://en.wikipedia.org/wiki/Raising_(metalworking) '''Raising'''] is a process which is used to produce deeper forms ''(without seams)'' than can be created by '''[[Hollowing]]''' ''(e.g. for deeper bowls, vases, trophy cups, goblets and challises)''.

A disc of '''[[Heat_Treatment#Annealing|Annealed]]''' metal is marked with concentric guidelines and slightly '''[[Hollowing|Hollowed]]'''. It is then presented at a steep angle to the end of a '''[[Stakes|Raising Stake]]''' and struck down on to it with a '''[[Silversmith's Hammer|Raising Hammer]]'''. The hammer is similar to a '''[[Silversmith's Hammer|Collet Hammer]]''' but heavier ''(e.g. 0.25 kilogramme (8 oz.))'' and both it and the '''[[Stakes|Raising Stake]]''' have all edges rounded and polished to avoid cutting the metal.

For production items, [https://en.wikipedia.org/wiki/Metal_spinning '''Spinning'''] has superseded '''Raising''' for repetitive articles, which may then be finished by hand.
