If you've ever had building works at your home, then you'll know that builders = dust. Of course, building dust occurs wherever works have been going on, including beautiful and historically significant properties which have been undergoing restoration work.
Kenwood House - English Heritage's much loved neo-classical Georgian house in Hampstead - is one such property, and a few weeks ago a team of our conservation cleaners were lucky enough to be involved with the post-restoration deep clean of the house.
For the past eighteen months Kenwood has been closed to the public while essential repairs and restoration works have been carried out to the roof and interiors of the house. (Its famous art collection has been touring the world.)
The reopening of the house in a few weeks time will reveal a total of eight rooms which have been restored and reinterpreted, with the Robert Adams interiors being returned as far as possible to their original design scheme.
After eighteen months of work you can imagine there was quite a lot of dust, so before any of the art and furniture could be returned to the house, the whole interior needed to be deep cleaned from the top down.
(The best way to remove building dust is with small brushes and museum vacuum machines.)
Generally, (as long as conditions are not too humid) building dust is relatively easy to remove, as it has not been sitting on surfaces for long periods of time. It does however cover everything, including vertical surfaces such as walls, so cleaning needs to be extremely thorough as well as extremely gentle.
Although we did clean them, we cannot talk about the new Robert Adams interiors in any detail – it would spoil the surprise! - however we can say that both long time lovers of the house and new visitors are most definitely in for a treat this winter when the house reopens.
There are few things more delightful than a wander around Kenwood’s stunning interiors and art collection, followed by a walk on Hampstead Heath (not forgetting a delicious slice of cake in Kenwood’s delightful Brewhouse Café of course) and with the restoration almost complete this North London pleasure can once again be enjoyed.
If you are a member of English Heritage you can buy tickets to an exclusive 'first look' at the completed house on 28th November 2013 - follow this link for details
If you've ever cleaned the top of cupboard, or high bookshelf, you'll know that just because things are high off the ground, doesn't mean they don't get dirty. Anything with a surface horizontal enough to stop a particle of dust or pollution from falling, will, over time, build up a layer of dirt. Decorative plasterwork is a case in point.
Beautiful mouldings in plaster have been used for centuries to decorate the interiors of rooms - particularly on high walls and ceilings - however just like surfaces closer to the ground, plasterwork needs to be cleaned to remain looking its best.
Cleaning chandeliers is one of our very favourite things to do. We do not use sprays - which leave a residue and can be very damaging - but rather each crystal is very gently cleaned by hand. Although it is meticulous and often painstaking work the results are always so lovely and satisfying. A newly cleaned chandelier is not only utterly beautiful itself, but it also completely transforms the look of a whole room.
No matter how smooth it's appearance, the thing about marble is that it is porous. And those tiny holes mean that dirt can easily become embedded in the stone. This causes discoloration overtime – like in the first photo – and cannot be removed with regular dusting.
One of our recent projects was cleaning a collection of 18th & 19th century marble busts; so in this blog we thought we'd explain a little about how we went about it.
There are various ways of cleaning marble. 'Wet' methods include the use of detergents, spirits, poultices and steam, but because the stone is porous these all carry risks and are invasive. The use of liquid Latex is also effective, however it widely considered overly invasive because the results often make the marble look too clean and new. 'Dry' cleaning is the least invasive method – and as you can see above the results can still be quite remarkable.
As the film The Hobbit continues to pack cinemas around the country, and attention is again focused on JRR Tolkien's extraordinary works, it seems like an apt time to revive one of our first blogs; Caring for Rare & Valuable Books.
In our original blog, we talked about a client of ours who wanted his collection of rare books cleaned and protected, and we explained how we went about this.
In an interesting aside, we actually recently cleaned and boxed a few additions to this client's collection, including two letters from Tolkien himself to a "Mr Jackson" regarding a stage production of The Hobbit. How cool is that! Maybe Peter Jackson would be pleased to know that a namesake and fellow "back-room boy of the drama" actually got to correspond with the great man.
Ever wondered just how dirty a London Underground sign becomes after years of hanging on the side of a tunnel? Well let me tell you. Pretty darn dirty.
This original sign (recently purchased by our client at an auction and destined to be displayed outdoors in his garden) arrived looking fairly clean on its front side; but on the reverse– as you can see – there was extremely thick layer of original London Underground grime. (There is grime, and then there is proper Dickensian grime, and this – I can assure you – was proper grime.) Unsurprisingly therefore, our first task in preparing this sign was to clean it thoroughly; and as the sign was enamel, this task was pretty straightforward i.e. mild detergent, warm water and a soft cloth. It took a while – and considerable elbow grease - but it came up a treat!
We have mentioned this subject before on this blog; however as Autumn is now very much upon us - and therefore so is central heating – and knowing the terrible damage which can occur through neglect of this issue, it seems right to revisit it, and impress again on all you owners of antique furniture, the importance of humidity.
This lovely little antique satinwood table used to live in a period property; and did so, very happily, for many years. Last summer the owner moved to a modern house, and by April of this year this is what had happened. Basically, a combination of better building insulation and central heating conspired to parch the wood of moisture, and caused the warping and cracking you can see in these photographs.
Built by the Courtauld family in the 1930s, Eltham Palace is not only an Art Deco architectural masterpiece, but it is built on the grounds of Henry VIII's childhood home, and as such combines original Tudor structures with stunning early 20th century design in a truely dramatic and beautiful mix of the Medieval and Modern.
From the palace's stunning Rolf Engströmer designed entrance hall and Virginia Courtauld's gold plated bathroom, to the restored Tudor banqueting hall and original moat bridge, this extraordinary place is quite truly a 'one off' and a wonderful place to visit and experience.
Just like all homes, historic houses need regular cleaning; and because of the amount of visitors they have (the more foot traffic, the more dirt) keeping interiors and collections clean is a constant concern.
At English Heritage's Down House – Charles Darwin's remarkable Kent home – the challenge is even greater, because not only is it one of the most popular visitor attractions in the South East (i.e. lots of foot traffic), but the Darwins' personal belongings are displayed just as they would have been when the family lived there.
Helping to care for the Werhner Collection (The Magnificent Decorative Art Collection of Julius Werhner - founding member of the De Beers's Diamond Company)
Have you ever taken a tour around Ranger's House in Greenwich? This stunning 18th century Georgian Villa, and magnificent fine art collection - amassed by a founding member of the De Beer's Diamond Company - is one of London's finest collections of European decorative arts, and a hidden jewell of South London.
We were very pleased to recently assist in the conservation cleaning of this collection.
All textiles are susceptible to environmental damage, and wall hangings and tapestries are particularly vulnerable because they are often displayed without protection. Pests, UV light and inappropriate hanging are three of the most important things to watch out for.
Pests are attracted to dust and dirt and will eat natural fibres, so keeping tapestries and wall hangings clean is a priority. The best way to clean textiles is with a museum brush vac (MBV) and textile netting, which allows dust and dirt to be gently sucked away without causing damage. Generally this type of conservation cleaning should be carried out every one to two years, depending on the location of the hanging. (If a hanging is located in a high foot traffic area then it should be cleaned more frequently.) Regularly check all tapestries and wall hangings for any signs of pests, and using a museum trap to monitor insect activity is advisable.
Although tortoiseshell, ivory and many types of bone, are rightly no-longer used in the manufacture of decorative items, for many centuries their beauty and malleability made them highly sought after materials for decorating everything from jewellery to furniture.
Ivory was used to make umbrella handles, piano keys and billiard balls, as well as being carved to make decorative figurines and used as inlays in furniture. Tortoiseshell was popular in the manufacture of hair combs and boxes, but was also more recently used to make guitar picks and glasses frames. Mother of pearl is still used to make jewellery and as an inlay, and some types of bone are still popular in the manufacture of knife handles and other decorative items.
David Lilly is a renowned restorer, designer and manufacturer of stained glass, and the founder of Simply Stained Glass www.simply-stained.co.uk. He is an expert in the care and restoration of both historic and modern stained glass, and in this interview provides some invaluable tips regarding conservation and maintenance, as well as discussing a few of his interesting projects.
Silver is a soft metal; it is easily dented, scratched or damaged. Always take care when handling it.
Touch your silver pieces as little as possible as fingerprints accelerate tarnishing.
All silver exposed to air will tarnish over time. Sulphur compounds - mainly hydrogen sulphide in the atmosphere – react with the metal and cause the surface to darken. Certain substances, however, cause tarnish to develop more quickly; these include wool, newspaper, rubber, paint, velvet, carpet padding and felt.
London Fashion Week is upon us, and over the coming days we will surely be wowed by the cutting-edge clothes on our capital's catwalks. This week is naturally about what's new in fashion; however, vintage clothing is also a passion for many people, and the desirability and collectability of vintage clothes has grown steadily over recent years.
Just like other fragile and delicate objects, clothing will deteriorate if not cared for properly, so below are a few tips on keeping vintage garments in good condition.
Ceramic Art 2012 and The Antique Ceramic and Glass Fair are both taking place at the end of the February. Here are our head conservation housekeeper's top three tips for looking after your decorative ceramics.
Firstly, in terms of display, try to avoid placing ceramics in high foot traffic areas, as this increases the likelihood of breakages. Displaying items behind glass will help keep them clean, and using museum wax to secure the base of a piece will stop it moving or sliding on a shelf.
Last week we were asked to clean a number of lovely Georgian antiques at a beautiful home in the Oxfordshire countryside. Well looked after, the pieces were in fine condition; however years of simple domestic dusting had allowed dirt to build up in the corners, carvings, and grooves of the pieces, and this had started to concern our client.
We were recently asked to have a look at a collection of seven first edition Tolkein books for a client in London. The books were in good condition and were stored adequately well - behind glass and along an internal wall - however the owner was anxious about their exposure to UV light (which passes through ordinary glass) and the possiblity of damage from insects.
