Silver Decanter Coaster - Bead Pattern
A handmade hallmarked sterling silver decanter coaster with a turned mahogany base. A solid mounted bead wire is soldered to the top edge for decoration and strength. It has a silver button in the centre and green baize underneath.
This sterling silver coaster is handmade in our Brentwood workshop. The mahogany base is from a recognized source and is turned on the lathe in our Brentwood workshop.
A silver coaster makes a perfect gift for any celebration, from a birthday to a wedding to a corporate gift or sports award. The silver button in the centre is particularly suitable for engraving, to mark the occasion and personalize the gift. An engraved item will always spark a discussion and bring back memories in years to come.
JA Campbell designs fall into 2 main categories, reproduction and contemporary. The reproduction collection consists of a variety of designs from different periods of history and is part of the JA Campbell 'Classic' range. The 'Appetite' is a matching collection of a more contemporary style.
Bottle stands and decanter stands, usually known as wine coasters were frequent accessories from the 1770s onwards. Today their main use is to protect whatever surface below from scratches and drips. They will also enhance the wine drinking experience.
For a more detailed description of the method of manufacture, John Campbell explains as below.
This particular coaster is made in one size only and consists of 6 components; the body, decorative bead top wire, centre engraving button, button fixing wire, mahogany base and green baize table protector.
The main body: this is made by the 'spinning' method from a silver washer. Spinning is an ancient process of making round, hollow objects from sheet metal, in this case silver. This process is suitable for short production runs, not unique to the silversmith and is used in other industries. Saucepans and lighting reflectors are often made this way.
Using a spinning lathe, a preformed shape or 'chuck' -as it is known- is screwed to the mandrill of the lathe and a sheet metal blank or disc, in this case standard silver, is clamped to it. While it is rotating and using a spinning tool, the silver is 'spun' (forced/wrapped) over the chuck until it fits snuggly. The 'spinning' tool is a highly polished steel burnisher fitted into a long wooden handle which the silversmith tucks under his arm and uses his body weight and leverage to move the metal.
Next, a measured length of bead wire (also made and supplied by Cookson Precious Metal) is turned up into a circle and an invisible solder joint is made to make it into a ring, using hard silver solder which will not melt during the subsequent soldering. The sides of the coaster are now pre-polished to remove spinning lines etc. The bead wire ring is stretched until it fits the top edge and pressed into place. The bead wire is then soldered onto the coaster body using a lower temperature solder than was used to join the ring ends. The assembly is now 'pickled' in dilute sulphuric acid to remove flux residues and oxides.
The silver engraving centre button: this is a small silver disc which is first domed in a press. A small indent is pressed into the back and a small casting (to hold it into the mahogany base) soldered to the back.
At this stage, the article is punched with the maker's mark, in this case JAC in a triangle, the initials of John Campbell the founder. Then it is taken to the London Assay Office to be scraped and tested. Once a positive result has been received from the LAO laboratory confirming that the article has been made with metal at least 92.5% pure silver, the remaining hallmarks are punched into the surface. This independent hallmarking process began in the 1400s and is still one of the world's oldest and most secure forms of consumer protection today.
On return from the hallmarking process, the marks are checked for any distortion or dents from the punches and are 'planished' out using a planishing hammer. Next the coasters are polished, using 3 grades of compound to their final, bright finish for which silver is known. They are ultrasonically cleaned and dried.
The mahogany base: these are made ourselves in house from sawn mahogany which we store here for several months to ensure it is completely dry and then plane down to ½" thickness. It is then cut into discs, drilled and fitted onto the lathe and turned to fit and then has decorative lines turned into the surface. A slot is turned into the back to hold the baize in place. The base is polished using 2 grades of compound until smooth and shiny. They then have their mahogany bases lapped in. Finally the polished silver button is pressed into its centre recess and the baize pushed into its slot. At last the coasters are ready to be fitted into their specially designed presentation boxes.
Generally speaking, a silver coaster is used for placing decanters, bottles or glasses inside thus protecting your highly polished table. Ideally suited to use with this silver bead coaster are a JA Campbell silver decanter, a silver bread bowl and silver cheese stand and matching silver cheese knife.
