Power House – Object Conservation 4

Object: Uniform Coat of the Duke of Wellington c.1835 (xvi.8)

Blogger: Suzanne Dalewicz-Kitto, Conservation Manager

This blue cloth uniform with white lining and scarlet facing was worn by the Duke of Wellington when he was Constable of the Tower of London. It has gilt buttons bearing a miniature of the White Tower in silver, and epaulettes made of gold and silver thread.  The coat is in reasonable condition with only a few small holes and surface grazing of the cloth, probably caused by moths.  The main area of interest to our Conservators were the tarnished metal threads and spangles (sequins) on the epaulettes.

Metal threads are fragile at the best of time.  Some are made from twisted fine metal wire and others are formed by twisting wire around a cotton or silk thread.  When applying treatments to remove the tarnish Conservators have to be careful not to leave residues behind that will ‘rot’ the thread over time.  On these epaulettes there are eight different types of thread design including: dull purl, pearl purl, bright check and Lizardine close.

The tarnish was removed by gently cleaning the surfaces with a damp swab using a mixture of carefully chosen chemicals.  This was carried out under a microscope to make sure no metal threads were being pulled away from the epaulette.  Residues where removed again by careful swabbing using deionised water – very pure water that has had any minerals filtered out of it.

This object will be featured in our forthcoming Power House exhibition at theTower of London which opens on Saturday 2nd April. Find out more about the work of our Conservation Team on our website.

Power House – Object Conservation 3

Object: Flintlock Land Service Musket (1715) XII.80

Blogger: Nyssa Mildwaters, Conservation

This musket is one of several experimental firearms which are to be included in the Power House exhibition. The musket was designed and made by the gunmaker Richard Wolldridge who worked at the Tower from about 1704 until 1749. Although this particular pattern or design was not issued to the military its does show the general form which British military firearms were beginning to take in the early 18th century.

The musket was is a very good condition prior to entering the Conservation Lab with only a small amount of old yellowed oil visible on the lock. Even though the exterior of the musket didn’t need a great deal of remedial work the lock mechanism was carefully removed from the musket, after of course checking that the firearm wasn’t loaded.

When working with firearms we will always, where possible, remove the lock mechanism in order to check the condition of the lock’s interior as well as the underside of the barrel. Often the interior of a lock can look very different to its external appearance, with combinations of dirt, old oil or wax and corrosion all potentially present.

Luckily in this case the interior of the lock was in a very good condition with no further cleaning or disassembly needed. The musket was therefore reassembled, making sure that the screws were replaced in exactly the same order they were removed. This is good practise as particularly with older firearms the screws threads will have been hand cut so using the wrong screw can damage both the screw itself as well as the internal thread.

Once the old yellowed oil was cleaned from the musket’s lock using solvent swabs the metallic sections of the object were given a thin coating of Micro Crystalline wax providing a protective layer. Finally the object was photographed and packaged for transport to the Tower of London.

Power House – Object Conservation 2

Object: Brass belt plate (mid 19th century) I.979 ii

Blogger: Nyssa Mildwaters, Conservation

It’s always nice to work on an object which can be related back to a particular person in history. This belt plate is one of a pair of objects relating to the Board of Ordnance’s only identified rat-catcher, Richard Dean.

The plate is the only surviving portion of Dean’s uniform and he can be seen wearing it in a portrait which is to be displayed alongside the plate. The brass belt plate is engraved with a rat shown sitting below the arms of the Board of Ordnance, whilst around the edge the inscription reads ‘Richard Dean, Chislehurst, Rat Destroyer to the Honorable Board of Ordnance’.

In order to make the letters and images engraved on the plate stand out a black enamel-like material was originally applied to the object. Unfortunately over time this material has cracked and in some areas has been lost. Where damage to the enamel had occurred traces of a powdery green corrosion could also be seen.  The powdery corrosion was carefully removed from the damaged lettering and other areas of decoration using a scalpel whilst under magnification. Once clean it was necessary to stabilise the enamel to prevent any further cracking or loss, this was done by running a thin adhesive solution into the damaged areas.

In addition to the problems with the lettering several finger and palm prints were clearly visible and spread across the plate. When we handle metal objects with our bare hands the sweat and oils on our fingers are transferred to the objects and if not swiftly removed can become etched into the objects’ surface. Sadly there is no way of removing finger prints once they are etched into a metal surface without removing the object’s top layer at the same time. Once fingerprints are imprinted they are generally there for good, which is why conservators always ask people to wear gloves when handling or moving objects.

Power House Installation: Week One

Blogger: Karen Whitting, Creative Programmes

Construction of the Power House exhibition at the Royal Armouries in the Tower of London began last week. Preparing the gallery for the installation has involved ripping out the old displays, which in an old building can be problematic if unanticipated issues are found.

Often all the pre-planning and preparation done prior to installation can be overturned in an instant – with new solutions and decisions needed immediately. However, with the right project team these moments feel more exciting and a challenge to be solved rather than finding them to be insurmountable problems.

 

Squeezing into the Tower of London

On day three of the build a clear blue sky greeted the delivery of the crane – an excellent situation as snow or high winds would have meant potential schedule delays. The crane lorry squeezed its way under the Tower’s historic archways and over bridges to take up residence, allowing the removal of the old exhibition material and lift in of new build items.

By day four it was apparent that the existing showcases had originally been screwed very firmly to the floor and each supporting foot had to be located and unscrewed before they could be moved to their new positions. However, as move after move took place and with a van and 2 builders skips of old material left the site, it was clear that a new exhibition was beginning to take shape.

As the first week drew to a close not only had all the cases been repositioned, they had also received a complete internal fit-out and one of our new cases was also finished. Everything was ready for graphic installation – and then objects…

More images of the installation at the Tower of London can be found on our Flickr page.

Power House – Object Conservation

Prior to installation of a new exhibition the objects which will appear on display have to be carefully cared for by the Conservation Team. Nyssa Mildwaters, one of the Royal Armouries Conservators, will be blogging about several interesting items which will soon be on display at the Tower of London.

One of the more unusual looking objects being conserved for the Power House exhibition is a three stemmed candlestick.  The main body of the candlestick is made from metal weapon parts which twisted and fused together during the blaze which destroyed the Grand Storehouse at the Tower of London on the 30th of October 1841.

Large numbers of weapons and other historic objects were destroyed by the fire, however in the weeks that followed tables were set up in what was left of the building and pieces of bizarrely twisted and shaped metal debris were sold off to members of the public at prices of up to £1 each.

This particular piece of debris was converted into a candlestick by drilling into the lump and then screwing on the three decorative stems, which as you can see have a very different appearance to the twisted and misshapen metal below. Although it is not possible to identify all the metal components which fused together forming the centre of the candlestick, yet to one side there is still clearly visible the remains of the lock or firing mechanism from a flintlock rifle.

Very little remedial conservation work was actually needed to get this object ready for display as it was already in pretty good condition if a little dusty. The dust and any dirt were removed using solvents swabs, after which the whole object was coated with a protective layer of Micro-Crystalline Wax. This was achieved by using a technique called ‘hot waxing’, where the wax is warmed during application to give a better and more even coating.  With conservation complete the candlestick is now awaiting packaging and transport to the Tower of London, ready for display.

The Naming of the Dragon

A fabulous “bejewelled” dragon – standing 3m high and specially commissioned by the Royal Armouries and Historic Royal Palaces – will create a guaranteed “wow factor” as the centrepiece of the Power House exhibition at the Tower of London.

A modern trophy, the dragon is made up of components representing each of the great institutions of state associated with the Tower. The design is still being finalised but the majestic beast is likely to include:

Power House Dragon

  • Ordnance Office – armour, swords, firearms and cannon to create the back legs and body
  • Menagerie – a cage for the ribcage
  • Prison – chains to create the tail
  • The Royal Mint – coins to represent the dragon’s fire
  • The Observatory – telescopes for front legs
  • The Records Office and Ordnance Survey – parchments and maps for wings
  • The Jewel House – fake diamonds and rubies for the dragon’s eyes

This is your chance to make history – a prestigious dragon such as this deserves a befitting name. The Royal Armouries has teamed up with History™ for your opportunity to win an exclusive behind the scenes tour of the Tower of London and two tickets to the VIP private view of the Power House exhibition.

To enter please suggest a name for the dragon by emailing the Royal Armouries at competitions@armouries.org.uk. Please include your name and telephone number on the email. The competition closing date is Thursday 31 March 2011. Terms and Conditions are available on the History™ website.

Collections Up Close March

In March 44BC Julius Caesar was warned to ‘Beware the ides of March’. Caesar dismissed the warning that harm would come to him, only to be stabbed to death later that day by Senators in the Roman Senate. The ‘ides of March’ refers to March 15th in the Roman calendar, and is probably linked to the full moon as the ides fall on either the 13th or 15th day of each month. The prediction and Caesar’s fate were later dramatised in William Shakespeare’s famous play ‘Julius Caesar’.

Roman Gladius and mounts

Roman Gladius and mounts (IX. 5583)

One of the oldest items in the Royal Armouries collection is a Roman Gladius, dated mid to late 1st Century BC. The sword is of the ‘Pompeii-type’, named after four swords found in the ill-fated city of Pompeii. Swords like this have also been found in Britain, France and Germany. In addition to the sword blade is a set of bronze scabbard mounts, engraved with a warrior carrying a spear and shield, as well as two depictions of the goddess Victory. These items are on display in our Leeds Museum in the Early War section of the War Gallery.
