In recognition of this Amgueddfa Cymru – National Museum Wales will be running a series of monthly blogs, each one covering a different chemical element and its significance to Wales. Look out for these throughout the year on our website.

To start off our series of blogs, for January we have silver.

Silver (chemical symbol – Ag), atomic number 47, is one of the original seven metals of alchemy and was represented by the symbol of a crescent moon. Silver is a precious metal, but it has never been as valuable as gold.

In Wales, silver has played an important role in the history of Wales, but this is often forgotten. In the northernmost part of Ceredigion (the old county of Cardiganshire) near to the village of Goginan lie a number of disused mines which were some of the richest silver producers in the history of the British Isles. The Romans almost certainly had a part to play in the discovery of the metal-rich mineral veins, but it was Queen Elizabeth I who oversaw their development as silver mines.

It is reported that the first rich discovery of silver was made at Cwmsymlog (sometimes written as Cum sum luck in historical records) mine in 1583 by Thomas Smythe, Chief Customs Officer for the Port of London. It is much more likely that it was discovered by Ulrich Frosse, a German mining engineer experienced in silver mining who visited the mine at about the same time and advised Smythe. During the reign of Elizabeth I it is estimated that 4 tons of silver was produced from the Cardiganshire mines.

King James I and King Charles I both made handsome profits from the mines (producing 7 and 100 tons of silver respectively), so much so that in 1638 Charles I decided to establish a mint nearby at Aberystwyth Castle. Its success ultimately led to its destruction by Oliver Cromwell and the Parliamentarians during the English Civil War in 1646.

Amgueddfa Cymru holds examples of the many silver coins minted at Aberystwyth. Their characteristic feature is the three feathers on both sides of the coin. The addition of a small open book at the top signifies that the silver was produced by Thomas Bushell from the Cardiganshire mines on behalf of the Company of Mines Royal.

Maps and mine plans produced to market the silver mines to investors are some of the earliest to have been made in Britain. The Library at AC-NMW holds several versions of William Waller’s maps produced for the Company of Mine Adventurers in 1693 and 1704 as well as Sir John Pettus’ Fodinae Regales published in 1670.

One of the mines, Bwlch-yr-eskir-hir [Esgair Hir], was much hyped as the Welsh Potosi and from the silver was produced a silver ewer inscribed ‘The Mines of Bwlch-yr-Eskir-hir’, c.1692. The mine was, however, a failure. The quantity of silver produced never lived up to expectations, but this was more to do with the geology than mining methods. It is perhaps better known as the site involved in a legal case against the Crown’s control over precious metals. The case, brought by the landowner Sir Carbery Pryse in 1693, ended the tyranny of the Mines Royal.

Productive silver mining continued in north Cardiganshire, firstly, under the Company of Mine Adventurers and then through the Industrial Revolution by a number of private companies. Total silver production within this part of Wales exceeded 150 tons of silver metal.

Remarkably, it took until the 1980s for geologists to identify the mineral responsible for the high concentrations of silver in the small area of Wales. It is tetrahedrite – a copper, zinc, iron, antimony sulphide mineral - within which silver can replace some of the copper, zinc and iron. At Esgair Hir mine tetrahedrite has been recorded as containing up to 18 wt. % silver. Important ore specimens used during the identification of this mineral are preserved in our geological collections at the Museum.

Naturally occurring silver metal – known as native silver – does not occur in visible concentrations in any of the Welsh mines, but the Museum holds some of the world’s finest examples in its mineral collection. The specimens, from the Kongsberg mine in Norway, are exceptional in their quality and were acquired during the 1980s as part of the R. J. King collection.

The National Waterfront Museum is one of the partners in the Angelshark Project, which aims to gather information, both current and historic, about this protected species, one of the rarest sharks in the world. Prior to a roadshow at the Museum on 15 and 16 February, Jake Davies, from the Zoological Society of London, shares his work.

Angels of Wales - How can you help?

Angel Shark Project: Wales is a pioneering new project with an aim to better understand and safeguard the Angelshark (Squatina squatina) in Wales through fisher-participation, heritage and citizen-science.

We are working with Amgueddfa Cymru and alongside fishers and coastal communities in Wales to better understand the Angelshark through gathering historic and current information about its life off the Welsh coast.

Angelsharks are large, flat-bodied sharks can reach 2.4m in length. Also known as monkfish or angel fish, they are sometimes mistaken for a ray or misrecorded as anglerfish. Angelsharks feed on a range of fish, crustaceans and molluscs and have an important role in maintaining a balanced marine ecosystem.

They are not threatening to humans, living mainly on sand or mud at the bottom of the sea, lying in wait to ambush unsuspecting prey.

Angelsharks are protected under Schedule 5 of the Wildlife and Countryside Act 1981.

It is illegal to intentionally disturb, target, injure or kill Angelsharks within 12 nautical miles of Welsh and English coastlines.

The four major areas of the Angelshark Project are:

1. Understand status and ecology of Angelsharks in Wales
2. Fishers are stewards of Angelshark conservation
3. Communities help unlock Angelshark heritage to share across the generations.
4. Develop Wales’s Angelshark Action Plan to identify key steps to secure their future

As part of the historical research, Angel Shark Project: Wales will be running the Angelshark History Roadshow from January to March 2019 in five of the project’s focal regions: North Anglesey, the Llŷn Peninsula, Porthmadog to Aberarth, Fishguard to Milford Haven and Swansea to Porthcawl (though we also welcome information from across Wales). The free events provide the opportunity to bring your memories, photos or stories of Angelsharks (or any other interesting shark, skate or ray species off the Welsh Coast) and see how they help build our understanding of Wales’s rich maritime landscape. The roadshows will also be a good opportunity to meet the team and find out more about the project. The roadshow dates are:

Following the roadshows, we will be recruiting and training citizen scientists to continue the historical research by scouring local libraries, archives, historic magazines and museums. Information captured through this research will be digitalised and displayed in collaboration with Peoples Collection Wales and provided to the next generation via a History of Angels iBook.

Those who are interested in being part of the project but unable to attend the roadshows and would like to share memories or photographs of Angelsharks can get in touch at angelsharks@zsl.org to help save one of the rarest sharks in the world. You can report personal sightings and accidental captures of Angelsharks to the sightings webpage http://angelsharknetwork.com/#map or email angelsharks@zsl.org.

Angel Shark Project: Wales is led by the Zoological Society of London (ZSL) and Natural Resources Wales (NRW), funded by the Heritage Lottery Fund and the Welsh Government.

Hope that you have been following our Natural Science #MuseumAdvent Calendar

Our curators and scientists in the Natural Science Department at National Museum Cardiff have been choosing their favourite objects from the collections, to place behind the doors of our very own museum advent calendar. As it is Christmas Eve, all of the doors are now open and we wanted to share with you all of the wonderful 24 objects chosen, and the staff who have helped created it. 

Why not have a look back through all of the doors and find out about these amazing objects and specimens within Amgueddfa Cymru collections.

Cultural heritage collections need a friendly home. 'Friendly' means: a building that protects the collection from the elements – wind, sun and rain. Conservators worry a lot - and rightly so - about pigments fading when they are exposed to light, about stuffed animals being eaten by insect pests, about wartime medals corroding because of the presence of air pollutants. But it’s no good having a fantastic pest management system if the roof leaks. Getting the basics right makes the job of the conservator an awful lot easier and is better for the collection.

Like many museums up and down the country, National Museum Cardiff is housed in a historic building. The museum contains 30 public galleries and 50 collection stores which accommodate almost 3 million objects. This is only part of the national heritage collection of Wales and arguably something we want to protect for the benefit of current and future generations.

But being in a historic building, as beautiful as it is, has its challenges. Much of the building infrastructure is aging and needs modernising. Our roof needs some tlc. Our air conditioning systems are so old, there is nobody left in the museum who was around when they were first installed. And the electrics in parts of the building are not far from receiving a birthday telegram from Her Majesty the Queen.

All of those issues are a problem not just for visitors and staff, but also for the collections. Therefore, we have started modernising our museum building. In the past few years we already had parts of our roof replaced. Less publicly visible was the recent replacement of the electrical infrastructure in the west wing. We are now in the process of undertaking much more work to improve the building.

Some of this work will happen behind closed doors: replacement of our chillers and humidifiers with new, modern and efficient technology, making the museum leaner and greener. Other work will be more obvious to our visitors, including works to the roof of our south wing. Various works will require the temporary closure of some of our public galleries – please bear with us during this time, we are keeping the rest of the museum open and, once the works are completed, all galleries will be accessible again.

One difficulty remains: once all the works are completed the museum will look like nothing ever happened – we do not have a brand new building to show off for all our efforts. BUT the building will feel and operate differently. It will form a more reliable envelope around our collections. It will require less maintenance, saving us money and staff time. It will be more energy efficient and environmentally friendly, reducing our energy bills and forming a substantial contribution towards lowering our greenhouse gas emissions.

During this time of potential disruptions please bear in mind the end product, which will include a better museum experience for visitors today (well, next year) and in the future. And a building that continues to help us look after Wales’ national collection.

Should you have any questions at all about our refurbishment programme in relation to the collections, please do get in touch. We will be happy to assist in any way we can.

We are busy preparing our Natural History #MuseumAdvent calendar and we couldn't resist sharing with you a sneak preview! This year the backdrop for the calendar is a snowy National Museum Cardiff. Each of our 24 natural science curators and scientists have selected one of their favourite objects from the collections to showcase each day. The advent calendar will feature on the @CardiffCurator Twitter account, so why not tune in each day and see what natural science specimen or object is behind each door. The calendar will feature plants, insects, sea worms, shells, fossils, minerals, seaweed and diatoms to name but a few. Once we have opened all of the doors, we will reveal the curators behind the favourite objects.
