Manufacture
See also: Alloys of silver used in jewelry and silverwareFor machine-made spoons, the basic shape is cut out from a sheet of sterling silver, nickel silver alloy or stainless steel. The bowl is cross rolled between two pressurized rollers to produce a thinner section. The handle section is also rolled to produce the width needed for the top end. The blank is then cropped to the required shape, and two dies are used to apply the pattern to the blank. The flash is then removed using a linisher, and the bowl is formed between two dies and bent.
To make a spoon the traditional by way of handforging, a bar of silver is marked up to the correct proportions for the bowl and handle.
It is then heated until red hot and held in tongs and using the hammer and anvil, beaten into shape. The tip of the bar is pointed to form the tip of the bowl, then hammered to form the bowl. If a heel is to be added, a section down the centre is left thicker. The edges of the bowl and the tip of the spoon are left thicker as this is where most of the thickness is needed. The handle is then started and hammered out to length going from thick at the neck and gradually tapering down in thickness giving a balanced feel. During this process the piece becomes very hard and has to be annealed several times, then worked again until the final shape is achieved.
The bowl is filed to shape, often using a metal template. The bowl is then formed using a tin cake and spoon stake. The molten tin is poured around the spoon stake and left to harden. The handle is then bent down to 45 degrees, and the spoon is hammered into the tin using the spoon stake and a heavy hammer, to form the bowl. The bend in the handle is then adjusted to match the other spoons in the set and so it sits correctly on the table. The bowl is then filed level, a process called striking off. The surfaces are filed, first with a rough file to remove the fire stain from the surface, then with a smooth file. It is then buffed to remove any file marks and fire stain from inside the bowl and is polished to the desired finish.

Famous quotes containing the word manufacture:
“Yes, that’s what I needed. Living flesh from humans for my experiments. What difference did it make if a few people had to die? Their flesh taught me how to manufacture arms, legs, faces that are human. I’ll make a crippled world whole again.”
—Robert Tusker, and Michael Curtiz. Wells (Preston Foster)
“Culture is an instrument wielded by teachers to manufacture teachers, who, in their turn, will manufacture still more teachers.”
—Simone Weil (1909–1943)
“I believe that the miseries consequent on the manufacture and sale of intoxicating liquors are so great as imperiously to command the attention of all dedicated lives; and that while the abolition of American slavery was numerically first, the abolition of the liquor traffic is not morally second.”
—Elizabeth Stuart Phelps (1844–1911)
