Silver Corkscrew - Loop Handle
This corkscrew has a solid silver handle and a steel worm type screw. This type of screw enters and removes the cork extremely efficiently and rarely splits a cork. The screw is mounted on a solid hallmarked sterling silver handle which has an interesting loop design, is nice to use and is also part of the 'Classic' collection by JA Campbell. For those wanting a higher value we can also use one of the carat golds for the making of this article.
Interested in how we make this product? A brief description follows: this corkscrew has 2 components, a silver handle and a steel corkscrew. The silver handle is cast for us by BAC castings. First a master pattern is made by hand in brass and is polished and silver plated. A vulcanized rubber mould is made of the handle and once finished it will be used to make wax copies of the original. The wax copies stand together (approx 6) on a base and are covered with a flask (an open ended tube) which is then filled with liquid plaster of Paris. Once it has set, it is warmed to melt the wax handles out.
The flask is then heated still further to about 1000 degrees C to burn out the remaining wax and once cooled, the molten silver is poured in to the recess aided by a centrifuge. Once this assembly has cooled down to about 200 degrees C, it is put in water which causes the plaster to break down and the casting to fall out. The castings are then 'pickled' in dilute sulphuric acid to remove remaining plaster and oxides before being cut apart. They are then fettled until smooth.
At this stage in the making the item is punched with the makers mark, JAC in a triangle, the initials of John Campbell. It is then sent to the London Assay Office for testing of each and every component. Only if all the components prove to be better than 92.5% are the remaining hallmarks punched into the surface while being supported on a steel stake. The English hallmarking system is one of the oldest, most trusted internationally, and best forms of consumer protection and dates back to the 1400s.
Upon return to the workshop, the newly hallmarked handles are screwed and soldered on the steel screw using silver solder. They are again pickled. Any excess solder is now filed off using small felt 'bobs' and brushes to access the small recesses. They are then polished using 4 grades of compound until the high lustre- for which silver is known- is reached. Ultrasonic cleaning and a final dry of the item follow and it is ready to be packed into fitted presentation boxes ready for dispatch. The screw is not stainless and so must not remain wet after use.
The history of the wine bottle is fascinating in itself and is worthy of further study but it is sufficient here in the history of the corkscrew to mention that the wine bottle was probably first seen in the first half of the 17th century. The very early corkscrews were manufactured by the gunsmiths of the day The first corkscrew is attributed to the end of the 18th century but the heyday of corkscrews coincided with the great period of British manufacturing and invention in the middle of the 19th century. At that time, men of vision were competing with each other to register patents for all manner of inventions and the corkscrew was included in these endeavours. The first corkscrew patent was registered to Samuel Henshall in 1795. The rise of the corkscrew is illustrated by the fact that between that time and the beginning of the 20th Century, over 250 corkscrew patents were registered. Out of interest a wine bar in Poole, Dorset had display cases with dozens of examples.
Materials changed as corkscrews became more common. Manufacturers introduced the use of precious metals including gold and silver. Other materials such as ivory, bone, enamel and other forms of decoration were pressed into use.
This silver corkscrew would make an ideal sterling silver men's gift or silver wedding present. If the occasion is a golden wedding, then the handle can be gold plated or even made in gold. As the sterling silver handle of the corkscrew can be engraved it is also very suitable for a corporate or incentive gift. A sterling silver engraved corkscrew could be something that is passed from generation to generation.
