Silver Corkscrew - T Bar
This corkscrew has a solid silver handle and a steel coil 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 rod handle. The handle has a double line motif which is the signature design theme of the JA Campbell, contemporary, Appetite collection.
For those interested in how we make this item a brief description follows. It is made from 3 components, a 'lost wax' cast stem, a steel screw and a length of silver rod. We can also make this item in carat gold for those looking for a higher value.
Lost wax casting: the stem is made by the 'lost wax' casting method and is formed by having a master pattern made and from that a rubber mould. Molten wax is injected into the mould to produce wax copies of the master. These wax copies are then placed together onto a central feeder stem and an open-ended steel tube called a 'flask' placed over them. This is then filled with liquid plaster of Paris and once it has set, is heated to melt out the wax. It is then heated even further to about 1200 degrees C, until the last remaining traces of wax have been burned completely. The flask is then allowed to cool down to about 400 degrees C and a carefully measured amount of silver 'spun' in using a centrifuge. The filled flask is cooled to about 200 degrees C and plunged into water causing the plaster to disintegrate and allow the castings to fall out. The castings are then 'pickled' to remove the plaster and oxide and then cut free from the feeder stem.
Silver rod production: this is made for us by Cookson Precious Metal and begins with the continuous casting method. Into the top hopper, 92.5% pure silver and 7.5% pure copper are loaded. This is the 925 UK standard or sterling silver standard alloy (as it has become known internationally). The metal drops into a crucible where it is melted and mixed. It then falls to the exit port at the bottom of the crucible where it begins to cool and solidify. Out of the exit, it is gripped and pulled at a continuous rate and then cut into manageable lengths. The resulting bars are then passed to the drawing shop where they are drawn down through a series of dies of a reducing diameter.
Steel screw: this is made for us by one of our trading partners in Germany. The steel rod is first threaded and then tapered to a sharp point. It is then wound around a tapered mandrill to form the screw, then hardened, tempered and cleaned. It is not stainless steel and must not be allowed to stay wet for more than a few seconds after use.
Silversmithing: this involves the assembly of all the components. The silver rod is cut to length and the ends 'linished' smooth, then placed in the lathe to have the pair of decorative lines added to each end. The ring on the cast stem is stretched up until the rod passes through snuggly. It is then up-ended, the joint fluxed and the 2 components soldered together to form the first handle sub assembly.
At this stage the article is taken to the London Assay Office to be scraped and tested. Once a positive result has been received from the laboratory confirming that the article has been made with metal at least 92.5% pure silver, the hallmarks are punched into the surface. This independent hallmarking process began in the 1400s and is one of the world's oldest, most trusted, and secure forms of consumer protection.
Upon return from hallmarking the unit, the steel corkscrew is then screwed in place and soldered to prevent it coming out. It is then filed smooth and polished using 4 grades of compound until it is bright. It is then ultrasonically cleaned, dried and packed into presentation boxes for dispatch or stocking.
The history of the wine bottle is interesting 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 early 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; 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 patent registered was 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 300 corkscrew patents were registered.
With the increasing use of corkscrews the materials used changed and this saw the introduction of more expensive metals including gold, bronze and silver. Other materials such as bone, ivory, enamel and other forms of decoration were pressed into use.
This silver corkscrew would make an ideal sterling silver men's gift or sterling 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 sterling silver corporate or incentive gift. A sterling silver engraved corkscrew could be something that is passed from generation to generation.
