All hail the dragon

Christian Baars, 7 Gorffennaf 2016

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.

Mission: Possible

Christian Baars, 1 Gorffennaf 2016

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.

Of dust bunnies and dust rhinos

Christian Baars, 23 Mehefin 2016

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.

How many dinosaurs does it take to change a light bulb?

Christian Baars, 14 Mehefin 2016

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.

Caring for the Evolution of Wales galleries

Claire Hamer, 6 Mehefin 2016

Between 20 June and 4 July, our popular Evolution of Wales galleries will be closed while we undertake some essential maintenance work.

For these two weeks, visitors will not be able to access areas showing the introduction, Big Bang, Carboniferous forest, dinosaurs, mammoth or the Ice Age animals. Other galleries remain open during this time, including the Diversity of Life gallery (with lots of birds), the mineral collection and all the natural history galleries with the British woodland scene, basking shark, hump back whale skeleton and our new exhibition Wriggle! The art galleries upstairs are also open, unaffected by the maintenance work.

The work covers improved care of the collections and sustainability of the building, including:

  1. Changing the gallery lighting to LED, to reduce electricity consumption, our carbon footprint and costs. LED lighting gives off less heat than conventional lighting so the air conditioning system will work better - it’s better for the items on display, because keeping a stable temperature helps maintain the condition of the objects. LED lighting also reduces future maintenance costs, and changes to the lighting will make the galleries brighter in some places.
  2. Improvements to the fire alarm system so it's better for the collections, the building, staff and visitors.
  3. Upgrading video screens from CRT to HD LCD with touch button interactive controls. This will improve video content delivery, reduce maintenance costs and provide a contemporary aesthetic to the gallery, making units more streamlined.
  4. While the galleries are closed curators will be able to secure some of the items that have become loose in the cases, thus improving their long-term care. They will also clean the displays thus reducing the risk of potential pest infestations – pest management is vital to the care of museum collections.
  5. Finally, installation of the new life-sized recreation of the new Welsh dinosaur, Dracoraptor hanigani as part of the dinosaur display.
