Amgueddfa Cymru — National Museum Wales

Home

In September 2016 Amgueddfa Cymru - National Museum Wales will again be participating in Open Doors, an event organised by Cadw (the Welsh Government’s historic environment service). The idea behind the event is to offer people the opportunity to visit a variety of sites important to the culture and history of Wales. The highlight of the event is the opportunity to visit places that are not normally, or are infrequently, open to the public.

The National Collections Centre, Nantgarw, is part of Amgueddfa Cymru – National Museum Wales, and houses thousands of interesting and important objects that are not on display. Although not normally open to the general public we have always offered access to researchers, and also to various groups and societies. Staff at the National Collections Centre have always seen the importance of opening up the site to allow visitors access to view some of these objects and to see the work that is carried out by staff on site.

We are always looking for new ways to get visitors on site, to encourage people to learn about what we do, and provide more access to the collections in store. Therefore we have decided to repeat last year’s success and get involved in Open Doors again. This year we will be open on two days as part of Open Doors, on Wednesday 7th September and Thursday 29th September 2016. There will be five tours on each day at 10.00, 11.00, 12.00, 2.00 and 3.00. Each tour will last about 45 minutes and visitors will be able to take a closer look at some of the collections held on site, and find out about the work of staff based here.

Booking is essential for these tours. Please ring us on 029 2057 3560 or 029 2057 3583 to book a place, or find out further information. You can also email us on industry@museumwales.ac.uk

Further details can be found on the Cadw website, as well as details of all other places open as part of Open Doors.

We hope as many people as possible will be able to enjoy the tours and be able to see some of the amazing objects preserved by Amgueddfa Cymru for the people of Wales.

During the past two weeks our Geology galleries were closed for essential maintenance. Now they are open to the public again, much to the delight of anyone looking after dinosaur-mad 6-year olds, who, quite rightly, have been disappointed by the temporary withdrawal of some of National Museum Cardiff’s most popular displays.

So in you come for a peek of all those refreshed displays. But what’s that? Seemingly nothing has changed?? Everything still looks as it did before the ‘major refurbishment’ – so what was so major about it?

The idea of undertaking maintenance was not to change the displays – apparently our visitors are happy with the way they are – but to update technology and fix things that were broken. This is why you have to look closely to spot what we have been so busy doing. Very busy in fact; including the planning phase, which took several months, we had at least 23 people working on the gallery. It was very busy every day, with staff and contractors working around each other, from the dinosaur foot prints pavement all the way up to the ceiling (which is 12m high in this gallery).

What you won’t notice is that the fire beams were replaced to alert us early and reliably in the event of a fire. You’ll have to look closely to spot the new lights: the spot lights underneath the ceiling are now all converted to LED. You may find that the image quality of the display screens is a million times better than it was before. What you certainly should notice is that the displays are much cleaner. We also repaired damage to displays. As the saying goes: if you touch - we need to touch up. The paint work, that is. And if anyone happens to walk into a display case the specimens inside move sometimes. If we don’t spot this early enough, they can topple off their shelf and break. We used the opportunity last week to put them all back in their place, hence our plea to you: this is now not a race to see how quickly they can be knocked off their perch again, so absolutely no prize for anyone who thinks they can dislodge the displays. Our specimens – which, actually, belong not to the museum but to the Welsh public – are fragile and repairing them costs tax payers’ money, which we do our best not to waste.

There is one thing that is entirely new to the gallery, something which will be obvious immediately to said 6-year old dinosaur enthusiast (and those of any other age, too): the new Welsh dinosaur now has a permanent home as part of our dinosaur display. A life-sized artist’s impression, feathers and colours and all, is now peeking from the early Jurassic back to its Triassic cousins. It is truly magnificent and inspiring, and actually one of the first models to represent the latest research that these kinds of dinosaurs were clad in feathers. The enthusiast in myself wants to add pathos to this announcement, which is difficult to express in a blog. Hence I’ll stop myself right here and simply invite you to come and see it.

Oh, one more thing. While working in the displays in the past two weeks we found countless sweet wrappers, discarded chewing gums and bits of sandwiches and apples in various hidden corners. These kinds of things encourage pests which we don’t want in the museum any more than you would want them in your house. We have the restaurant, café and schools sandwich room where you are welcome to eat, and there are bins in the Main Hall before you enter the galleries. We would be immensely grateful if you didn’t take any food into the galleries.

In the last two weeks our Geology galleries at National Museum Cardiff have been closed to the public due to major refurbishments. We are coming to the end now, we are just asking for your patience for a few more days before opening the permanent exhibition again.

We have already written about some of the work in the gallery: cleaning and repairing displays and changing lighting. In addition, we have replaced display screens and fire beams, and here’s why and how.

There are a number of videos in the galleries which used to be played from medieval cathode ray tubes – if you are as old as me you will remember the old TV screens which were always surprisingly front-heavy when you had to lift them. They are larger (deeper, which limits exhibition space), use more electricity and have a lower resolution than the new flat screens we just installed. If you are a regular visitor you will notice that the screens are not sticking out of the wall as much as they used to. And the resolution is sooo much better now! The videos are now much clearer for you, the visitor, while we, the museum, will save money on our electricity bills which we can then invest in improved collection care and exhibitions – everybody wins.

At the same time we used the gallery closure to work at height – underneath the ceiling, to be precise. Fire safety is more than a legal requirement for us; it is part of our work to care for the national collections. After all, if the museum burns down a large part of your heritage disappears forever. From time to time, even fire and smoke detection equipment needs servicing. This was undertaken this week by a specialist company. And this certainly caused a bit of a stir in the building.

As in your house, the smoke detection equipment is situated underneath the ceiling. It’s just that the ceiling in our Geology galleries is about 12m high. We can’t get there with ladders or scissor lifts, not to speak of all the displays that are in the way. The solution was to climb up the walls. So if any staff are still wondering what why there was a man dangling from the ceiling – it wasn’t a burglar, as in the 1996 film Mission: Impossible, but a rope access operator keeping the museum save from fire.

We are now in the process of completing the last few pieces of work and cleaning up in the next few days. The exhibition will be open to the public again on Tuesday 5th July.

Our Geology galleries at National Museum Cardiff are still closed for essential maintenance. We are changing things around a bit – out with the old and in with the new: we are changing old display screens for new ones; old light bulbs for new ones; old fire beams new ones; old dust – well, for no dust at all. Yes, the dinosaurs are having their vertebrae tickled to release some of the dust of the centuries and keep them looking pretty.

Actually, if you have been to see the dinosaurs recently there is a good chance you have left some of yourself on them. Dust in our galleries is composed of tiny particles that come into the building through our ventilation system (although we have very good air filtration). Other dust particles are fibres from the clothes you wear. But the bulk of dust is, actually – well, there is no easy way of saying this: bits of YOU. Especially hair and skin.

Humans are living beings whose bodies renew themselves constantly. Our skin is our largest organ. New cells are formed constantly at the base layer of the epidermis (the outer part of the skin). These new cells move up through the layers of the epidermis and die as they are further away from blood vessels that supply nutrients. Eventually they reach the corneum, the outermost layer, and slough off.

We love having you in the museum (actually, next time you visit why don’t you bring a friend who hasn’t been for a while). But if you shed your skin while you are in the museum you are inevitably leaving a small part of your body in the building. Nice.

These particles are tiny and very light. They will happily settle on surfaces. Our dinosaurs (and, of course, all other displays) provide ideal surfaces for dust to settle. And no, dust bunnies do not evolve into dust rhinos – so there is no need to set up protective zones to save these cute little things.

Dust will form a layer on objects, which, contrary to popular opinion by people who dislike cleaning, is not protective. On the contrary: dust attracts moisture from the air and then becomes very reactive, which can lead to corrosion and other forms of damage to our objects. This is not only unsightly but can result in expensive conservation treatments or even irreparable damage.

We’re in the business of heritage preservation for the long-term. We want to help keep all of the important national collections for generations to come. This includes removing your dead skin cells from the dinosaur skeletons while we have the space to work in the gallery.

And no, we would not get rid of our vacuum cleaner because it is only collecting dust.

Our Geology galleries are going to re-open on Tuesday 5th July.

Next week our dinosaurs will go to sleep for two weeks. The Geology exhibition will close for “essential maintenance” – you will have seen similar signs in other places. In our case “essential maintenance” does not mean that the dinosaurs’ toilet is blocked (now we do have coprolites on display but they are well and truly fossilised). But if you thought all the light bulbs were blown and we have to fit new ones you wouldn’t be far off. Except that we never did have any black holes in our galleries – no need to bring miners’ lamps which are absolutely reserved for Big Pit.

What we are going to do does indeed involve changing light bulbs. We need light in order to see, and without light we would not be able to appreciate most objects in museums. Light, however, can damage many types of objects. You may have noticed at home that old photographs fade, as do organic inks and pigments on prints and paintings. Leave a newspaper out on the window sill for a few days and it will have yellowed.

In the museum, where we preserve objects for posterity, the damage done by light can be a major problem. Any such damage is irreversible and cannot be repaired by our best conservators. Ultraviolet (UV) radiation is particularly damaging. How long do you think museum objects should last? As part of our collections care, we plan lighting in galleries carefully to leave colours bright and vivid for as long as possible.

The new lighting systems we are fitting this month at National Museum Cardiff will be more energy efficient. In addition, the new lights will be of better quality which means you will see objects more vibrantly yet safely, without causing unnecessary fading. Because the new lights also produce less heat they will make it easier and cheaper to air condition our galleries.

Changing the lights is not all we are going to do – there are a myriad of additional jobs to be done while we have the opportunity. All this takes a little time – between the 20th June and 3rd July. It won’t really be the dinosaurs changing their own lights, of course – there will be technicians, curators and conservators busily climbing ladders and scaffolding.

We do all we can to preserve our national collections and to improve our sustainability. So please bear with us when you see the signs and come back to see the Geology galleries in a new light in early July.
