Tinned Copper Saucepan, Raised from Sheet and Riveted
A copper saucepan heats evenly; lined with tin, it keeps the copper away from the food. Raise a copper disc into a pan over the stake, anneal it whenever it stiffens, rivet on an iron handle, then tin the inside as Andrew Ure (1839) describes: scour, heat, rub with sal ammoniac, melt tin with rosin on it and wipe it over with tow.
The picture: copper saucepans with riveted iron handles in the kitchen of Bourbilly Castle, Burgundy.

Tin the inside
Tin the inside
Scour the inside bright with sandstone. Heat the pan and rub it with sal ammoniac until perfectly clean. Put tin and a little pounded rosin in, keep it hot enough to melt the tin, and spread it thinly over the whole inside with a pad of tow. Work outdoors: the sal ammoniac fumes.
