This technique (spinning), a follow on of the Industrial Revolution widely applied in 19th century, smoothes also the pot's inside, avoids soldering and hammering signs (unless later intentional additions) but produces objects of meagre solidity and weight, requiring a double hem to reinforce the edge (obviously, 'spinning' technique may not be applied on a 1745 coffee pot). Close research of possible forgery or transposition and/or alterations of hallmarks Some further caution is requested examining items of good weight made in England between 17, owing to 'duty dodging' practices.

In 1720, when 'sterling' standard (925 ppt) was reinstated after the compulsory use of Britannia standard (958,4 ppt), a 6 pence duty per troy ounce of silver was imposed on silverware production and trade.

For a collector who prefers to search and buy items out of the traditional - and sometimes expensive - antique retailer shops, a valid alternative way is to collect as much informations as possible about the style evolutions and patterns of the object he intends to buy.

Furthermore it is necessary to adopt a rigorous and pragmatic approach, trying to avoid emotional factors which may affect the correct evaluation of the item.

A second technique, applied by a wider number of silversmiths, used a 'raising' technique only for some parts of the pot (the base and the lid) while the body was made bending a plane sheet of silver, soldering its edges ('seaming') and hammering the cylinder until the appropriate shape was obtained.

The shape of the lid (wrapping over the rim, without a sleeve fitting outside) is typical of the years around the 1745 (Ian Pickford, 2003.

From this point of view our coffee pot looks to be a piece of great gauge and quality as anyone would expect from an English silver of the first half of 18th century. Hallmarks research and their examination (individual and as a set) Now we research coffee pot hallmarks.

Hallmarks in exposed positions are often rubbed and difficult to read on antique silver, due to the repeated polishing of the item.

On the pot's inside there are signs of hammering, mainly on the base and inside the lid obtained by 'raising' or requiring more hammering (where hammer's traces where not smoothed down).

The spout and handle's supports were obtained by moulding.
