Arthur F. Payne · Public domain (1914)
Teaspoon Sawn Short from Silver Sheet, Then Hammered Out (Payne 1914)
Saw the spoon out of flat silver smaller than it will end up: shorter, narrower in the bowl and thicker in the shank. Hammering then stretches it to full size. Arthur Payne said this method was used largely for silver teaspoons.
Source: A. F. Payne, Art Metalwork with Inexpensive Equipment (1914), pp. 180–184; annealing from his chapter XI. The millimetre figure is ours. Picture: Payne's Fig. 155, the blank and the finished spoon.

Mark out and saw the blank from 15-gauge sterling silver (about 1.45 mm; our conversion): 5 in long, the bowl 1⅛ in wide and the shank 5⁄16 in wide. The finished spoon will be 6 in long with a bowl 1⅝ in wide.

Anneal to even the fire scale
Anneal to even the fire scale
Anneal the spoon thoroughly once more. Heated silver grows a thin white skin, the fire scale, and this brings it back over the spots where filing and polishing took it off, so the colour is even.
