Silver Cocktail Shaker
A handmade hallmarked sterling silver cocktail shaker with the double turned line decoration, in the slightly deco/fourties style, and part of the 'Appetite' collection. It is made by a mixture of silversmith techniques including 'spinning', 'seaming' and 'planishing'.
A silver cocktail shaker is the essential ingredient in the making of the perfect cocktail. This shaker is functional, stylish and elegant. Its theatrical use is a must for drinks that need to be shaken not stirred. It is an essential! on the bar of a luxury home, yacht or plane. This silver cocktail shaker will not fail to impress your guests and friends. Neither would it look out of place in the occasional palace. Silver has become a subtle status symbol in recent years. For your own self indulgence, and to pass as an heirloom to future generations, a gift for the man who 'has everything', a corporate gift or even an incentive gift.
This cocktail shaker with its smooth sides is an ideal item on which to engrave a message of your choice, or perhaps names, dates, family crest, company logo or the name of the yacht. The design features and quality in every item made by craftsmen at JA Campbell are unique.
A detailed description of the manufacturing process follows. The shaker is made entirely from silver sheet, 2 discs for spinning, 1 as a base piece and 1 part cut to a template that will form the tapered body.
Spinning explained: This is an ancient method of producing round hollow sheet made objects on a lathe and is most suitable for small production runs. Indeed it is not unusual to find lampshades and kitchen utensils made this way. Using a metal spinning lathe, a preformed shape known as a 'chuck' is screwed on to the mandrill of the lathe and a flat metal disc (in this case silver) is 'spun' or wrapped around the chuck while it is rotating, hence the term spinning. A polished steel burnisher fitted into a long wooden handle is tucked under arm of the spinner/silversmith and used to lever the disc on to the chuck, using his body weight for power. As you can imagine the metal tries to buckle and fold as it comes off the flat plane and begins to form a hollow object and it is the skill of the spinner to prevent this happening. Once the silver has been spun onto or over the chuck the uneven edges are trimmed to their finished height, using a hand held turning tool.
The main body template, cut from sheet is rolled using a cylinder roller until both edges meet. It has 3 stainless steel rods laid along its length and a spiral of iron 'binding' wire wound around from end to end. This is to pull the butted seam edges exactly together. This cone now formed is covered with the fire stain preventative Argotec, the joint fluxed and placed in its soldering cradle. It is then heated with a gas and air torch until red hot and allowed to cool and the binding wire carefully removed. The seam is fluxed over again, reheated and soldered using enamelling solder. This is the highest temperature silver solder in the range. Once cooled it is 'pickled' in dilute sulphuric acid to remove flux and oxide residues, rinsed and dried.
The next stage is to dress the seam area removing surplus solder of which there is a considerable amount. Only about 5% of all the solder applied is needed to make the joint. The body is now pushed onto a tapered chuck on the lathe and 'planished' with the flat side of the spinning tool. It is then made red hot (annealed) to soften and planished again, this time with a wide planishing tool. This makes the body very straight, flat and smooth. 2 lines are turned into the body for decoration. It is then held on a jenny machine which swages out a half round roll at the top of the body to grip when pulling the cap off. The removable body cap has a corresponding roll swaged in the same as the body.
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 and best forms of consumer protection and dates back to the 1400s. Upon return from hall marking the bottom blank is soldered on to the bottom of the body after firstly fitting the soldering ring which will prevent the body going oval during the heating process. It is once again pickled before being passed to the polishing shop where Colin and his team, using 4 different grades of compound polish it to the brightness associated with silver. Ultrasonic cleaning takes place and the item is then rinsed, dried and inspected. It is finally packed into fitted presentation boxes.
