	After soldering, the 'seamed' object is '''[[Pickling\|Pickled]]''' to clean it of oxides after which it is ready for further work ''(e.g. one end can simply be flared out by holding it at an angle to a cylindrical '''[[:Category:Stakes\|Stake]]''' and striking it with a '''[[Silversmith's Hammer\|Raising Hammer]]''' or '''[[Silversmith's Hammer\|Collet Hammer]]''')''.

			Once the seamed product is completed, it can be trued, the metal '''[[Crystalline_Structures#Work_Hardening\|Work Hardened]]''' and polished, by a process known as [https://en.wikipedia.org/wiki/Planishing '''Planishing''']. 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. Bases, handles, lids, and any applied decoration for example, may be added by '''[[Hard Soldering\|Silver Soldering]]''', '''[[Soft Soldering]]''', or '''[[Riveting]]'''.

=====Description=====

'''Seaming''' is a process whereby flat sheets of metal are rolled and joined at their 'seam' to form cylinders or cones as a starting point for further work when creating '''[[:Category:Beaten Metalwork|Beaten Metalwork]]''' articles.

=====Features and Applications=====
[[File:DovetailCylinder.png|right|400px]]

The 'seams' are commonly joined by '''[[:Category:Hard Soldering|Hard Soldering]]''' using '''[[Silver Solder]]''' for example. Straight 'seams' are common, and are suitable for most purposes, but traditional '''Copper Kettles''', for example, have 'seam' joints '''Dovetailed''' for extra strength before soldering.

Once soldered together, the 'seamed' form can be further worked by '''[[Raising]]''' techniques, for example, and then '''[[Planishing|Planished]]'''. Bases can be added, as can spouts, feet or surface decoration for example, by working through the grades ''(i.e. melting points)'' of '''[[Silver Solder]]''' and finally down to '''[[Soft Solder]]'''.[[File:FilingConeCylinder.png|right|300px]]

=====The Seaming Process=====

The flat sheet is first rolled into the required cylinder or cone and the 'seam' filed to the closest fit possible ''(all solders flow by a process of [https://en.wikipedia.org/wiki/Capillary_action '''Capillary Action'''] so the joint needs to be clean and close fitting)''.

[[File:FileViceCylinderCone.png |right|300px]]
Filing at this stage also helps to ensure that the metal edge is filed to a slight bevel such that close metal to metal contact is maintained throughout the sheet thickness.

Some [https://en.wikipedia.org/wiki/Silversmith '''Silversmiths'''] prefer to hold the 'tang' of a file in a vice and simply rub the 'seamed' joint backwards and forwards along it to achieve a good close fit.

[[File:WiredCylinderCone.png |right|300px]]
Once a close fitting 'seam' has been achieved, the metal is thoroughly cleaned ''(e.g. with '''[[Emery Cloth]]''')'' and held together with hoops of soft iron binding wire prior to soldering. Twisted loops are included which can be further twisted to pull the joint together. Conical forms also require wire hoops around the ends to which the circular hoops are attached so that they don't slip towards the narrower end of the cone.

After soldering, the 'seamed' object is '''[[Pickling|Pickled]]''' to clean it of oxides after which is is ready for further work ''(e.g. one end can simply be flared out by holding it at an angle to a cylindrical '''[[:Category:Stakes|Stake]]''' and striking it with a '''[[Silversmith's Hammer|Raising Hammer]]''' or '''[[Silversmith's Hammer|Collet Hammer]]''')''.
