National Waterfront Museum's GRAFT Team Spread Seeds and Sunflowers During Lockdown

Angharad Wynne, 28 April 2020

While The National Waterfront Museum’s GRAFT team and volunteers cannot gather to garden the Museum’s courtyard garden at this time, they are nonetheless keeping busy setting up ‘Seeds Out in the Community’ and encouraging us all to grow sunflowers in visible and public spaces to show support for key workers. Here’s a little more about this innovative community project and how it’s grown from a seed of an idea to a flourishing project that grows plants, food and people.

GRAFT: a soil based syllabus is the National Waterfront Museum's edible land and educational project, and a permanent piece of green infrastructure within Swansea City Centre. The project is also a socially engaged work of art by artist Owen Griffiths, and was originally commissioned as part of Now the Hero / Nawr Yr Arwr in 2018 funded by 1418NOW as part of a huge UK wide cultural project commemorating the first World War.

GRAFT works with community groups from a wide range of backgrounds across the city who came together, to transform the Museum's once industrial courtyard into a beautiful, sustainable, organic growing environment; creating an edible landscape to encourage participation and conversation around land use, food and sustainability in an accessible and empowering way.

Owen and Senior Learning Officer Zoe Gealy develop the ongoing program at GRAFT around these ideas of collaboration, sustainability and community. Every Friday, (other than during this lockdown), volunteers young and old work alongside one another to share skills working in wood and metal, learning how to grow plants, gaining qualifications and supporting each other along the way. The project has seen successful apprenticeships develop as a result of its program as well as seeing the long-term mental health benefits of working outside together. New friendships are formed, and people, as well as plants, flourish. During GRAFT’s development, in addition to raised beds, a pergola and benches from local timber, a cob pizza oven and beehives have been introduced to the garden. GRAFT's youngest volunteers come from Cefn Saeson School in Neath and work with Alyson Williams, the resident Beekeeper, learning about biodiversity, the environment and working together to care for the bees.

Some of the produce grown in the garden usually makes its way into delicious meals at the Museum's café whilst some is used for community meals at GRAFT. A portion of produce is used by volunteers, and some is donated to projects and groups throughout the area who provide food for those in need, such as Matts House, Ogof Adullam and the Swansea refugee drop in centre.

SPREADING SEEDS AND SUNSHINE DURING LOCKDOWN

Over the coming weeks GRAFT will be posting seeds through City and County of Swansea’s food parcel scheme and to community groups they regularly work with such as Roots Foundation and CRISIS. The seeds include squash and sunflowers, which were harvested by the gardeners last season.

Another initiative GRAFT is developing in the coming weeks is encouraging people to plant sunflowers in visible and public spaces, to show support for key workers alongside rainbow paintings. People are also invited to post pictures of their successful growing on GRAFT’s social media pages.

United Nations International Year of the Periodic Table of Chemical Elements: October – Sulphur

Christian Baars, 23 October 2019

2019 is the 150th anniversary of the Periodic Table of Chemical Elements (see UNESCO https://www.iypt2019.org/). The "International Year of the Periodic Table of Chemical Elements (IYPT2019)" is an opportunity to reflect upon many aspects of the periodic table, including the social and economic impacts of chemical elements.

Sulphur is the fifth most common element (by mass) on Earth and one of the most widely used chemical substances. But sulphur is common beyond Earth: the innermost of the four Galilean moons of the planet Jupiter, Io, has more than 400 active volcanoes which deposit lava so rich in sulphur that its surface is actually yellow.

Alchemy

The sulphate salts of iron, copper and aluminium were referred to as “vitriols”, which occurred in lists of minerals compiled by the Sumerians 4,000 years ago. Sulfuric acid was known as “oil of vitriol”, a term coined by the 8th-century Arabian alchemist Jabir ibn Hayyan. Burning sulphur used to be referred to as “brimstone”, giving rise to the biblical notion that hell apparently smelled of sulphur.

Mineralogy

Sulphur rarely occurs in its pure form but usually as sulphide and sulphate minerals. Elemental sulphur can be found near hot springs, hydrothermal vents and in volcanic regions where it may be mined, but the major industrial source of sulphur is the iron sulphide mineral pyrite. Other important sulphur minerals include cinnabar (mercury sulphide), galena (lead sulphide), sphalerite (zinc sulphide), stibnite (antimony sulphide), gypsum (calcium sulphate), alunite (potassium aluminium sulphate), and barite (barium sulphate). Accordingly, the Mindat (a wonderful database for all things mineral) entry for sulphur is rather extensive: https://www.mindat.org/min-3826.html.

Chemistry

Sulphur is the basic constituent of sulfuric acid, referred as universal chemical, ‘King of Chemicals’ due to the numerous applications as a raw material or processing agent. Sulfuric acid is the most commonly used chemical in the world and used in almost all industries; its multiple industrial uses include the refining of crude oil and as an electrolyte in lead acid batteries. World production of sulfuric acid stands at more than 230 million tonnes per year.

Warfare

Gunpowder, a mixture of sulphur, charcoal and potassium nitrate invented in 9th century China, is the earliest known explosive. Chinese military engineers realised the obvious potential of gunpowder and by 904 CE were hurling lumps of burning gunpowder with catapults during a siege. In chemical warfare, 2,400 years ago, the Spartans used sulphur fumes against enemy soldiers. Sulphur is an important component of mustard gas, used since WWI as an incapacitating agent.

Pharmacy

Sulphur-based compounds have a huge range of therapeutic applications, such as antimicrobial, anti-inflammatory, antiviral, antidiabetic, antimalarial, anticancer and other medicinal agents. Many drugs contain sulphur; early examples include antibacterial sulphonamides, known as “sulfa drugs”. Sulphur is a part of many antibiotics, including the penicillins, cephalosporins and monolactams.

Biology

Sulphur is an essential element for life. Some amino acids (cysteine and methionine; amino acids are the structural components of proteins) and vitamins (biotin and thiamine) are organosulfur compounds. Disulphides (sulphur–sulphur bonds) confer mechanical strength and insolubility of the protein keratin (found in skin, hair, and feathers). Many sulphur compounds have a strong smell: the scent of grapefruit and garlic are due to organosulfur compounds. The gas hydrogen sulphide gives the characteristic odour to rotting eggs.

Farming

Sulphur is one of the essential nutrients for crop growth. Sulphur is important to help with nutrient uptake, chlorophyll production and seed development. Hence, one of the greatest commercial uses of sulfuric acid is for fertilizers. About 60% of pyrite mined for sulphur is used for fertilizer manufacture – you could say that the mineral pyrite literally feeds the world.

Environment

Use of sulphur is not without problems: burning sulphur-containing coal and oil generates sulphur dioxide, which reacts with water in the atmosphere to form sulfuric acid, one of the main causes of acid rain, which acidifies lakes and soil, and causes weathering to buildings and structures. Acid mine drainage, a consequence of pyrite oxidation during mining operations, is a real and large environmental problem, killing much life in many rivers across the world. Recently, the use of a calcareous mudstone rock containing a high proportion of pyrite as backfill for housing estates in the area around Dublin caused damage to many houses when the pyrite oxidised; the case was eventually resolved with the “Pyrite Resolution Act 2013” allocating compensation to house owners.

Conservation of museum specimens

Because iron sulphides are highly reactive minerals, their conservation in museum collections poses significant challenges. Because we care for our collections, which involves constantly improving conservation practice, we are always researching novel ways of protecting vulnerable minerals. Our current project, jointly with University of Oxford, is undertaken by our doctoral research student Kathryn Royce https://www.geog.ox.ac.uk/graduate/research/kroyce.html.

Come and see us!

Time to chill

Christian Baars, 2 August 2019

One of the best reasons for housing heritage collections inside buildings is that the building keeps the weather out. Paintings, fossils, books and skeletons are best kept dry, and walls and roofs protect our collections (as well as staff and visitors) from the elements.

In addition, many of the objects in our collections also need specific temperature and humidity ranges to prevent them from suffering damage. Too high a humidity can cause swelling of wood, for example, initiating cracks in objects, or, if humidity gets even higher, mould growth. Therefore, National Museum Cardiff has a complicated air conditioning system. This system is more than 40 years old and has been maintenance-intensive and inefficient for some time.

We are happy to report that, after several years of planning, we have just completed the installation of new chillers and humidifiers at National Museum Cardiff. The purpose of chillers in the museum is to provide cold water – for lowering the temperature of galleries and stores in the summer, and for dehumidifying stores and galleries if there is too much moisture in the air. Humidifiers achieve the opposite effect: they increase humidity in stores and galleries if it is too low. Low humidity is usually a problem during the winter months – you may have experienced your skin drying out at home when you have the heating on in winter. To prevent our collections drying out we cannot apply skin cream; instead, we maintain a minimum level of humidity in stores and galleries.

The chillers and humidifiers have been commissioned now, and are working well. They have already proved that the control of our indoor environments is better than it was before. A very positive side effect of the new technologies is that they are much more efficient than the old equipment. In fact, they are so efficient that we are anticipating to shave almost 50% off our annual electricity bill for National Museum Cardiff, saving the planet more than 500 tonnes of carbon dioxide every year. That is the equivalent of taking 100 cars off the road, or the average energy a family home uses in 38 years.

By investing in such new technologies, Amgueddfa Cymru – National Museum Wales continues to ensure the safe storage and display of the nation’s heritage collections, whilst at the same time making a massive contribution towards the National Assembly’s commitment to reduce carbon emissions by 80% by 2050 (Environment Wales Act 2016).

SECRET GARDEN: Brian’s Story

Brian, Volunteer , 26 June 2019

My name is Brian and I live in Talbot Green. When I was in school I used to do gardening in Y Pant. In the winter I used to help my dad in the garden.

I worked in Remploy in Tonyrefail for ten years starting in 1974. We used to do all sorts of jobs. Then I did four years in Llantrisant, and twenty five years in Porth. On Fridays we finished early and went to the pub for lunch. I retired in 2013. I have the opening plaque from when Remploy opened in Porth in 1988. The building has been demolished.

Since I retired I have done a computer course and a photography course. I have also done pottery and pop art, and I have a big collection of paintings that I have done.

I came to the Take Charge coffee morning in August 2018 and found out about the chance to help at The Secret Garden at St Fagans National Museum of History. That’s when I decided to start gardening again. I’ve learned about teamwork, we work here in a team.

I enjoy doing it, I feel happy. I look forward to coming out and abought especially. I feel tired after, but good tired. My favourite job is raking. I’ve learnt that I enjoy volunteering.


The Secret Garden is maintain and developed by Innovate Trust whose main work is to support people with learning disabilities, mental health issues and people with physical impairments.

 

Your national museum is changing - from the inside out

Christian Baars, 9 March 2019

Were you amongst among the record number of people who enjoyed our recent ‘Tim Peake’ and ‘Leonardo da Vinci’ exhibitions at National Museum Cardiff? Did you realise that, while you were in the public galleries, there were workers with hard hats and power tools working to improve the building?

We are currently undertaking a large amount of maintenance works in the museum. We do this in such a way to minimise the disturbance to our visitors as much as possible. We want you to enjoy your experience at the museum and be inspired. During the coming months, however, scaffolding will be erected around parts of the building. We are also going to get a temporary over roof on the oldest part of the museum.

Given that this part of the building was opened as long ago as April 1927 by King George V it is now due some tender loving care. Owing to the ravages of time, the roof has developed a few leaks which we are going to repair this year. This also involves having to close some galleries temporarily, for example the Ceramics and Photography galleries. We do apologise for the inconvenience, but these closures are necessary to allow us to undertake the work on the roof and associated internal works.

Galleries will reopen refreshed in the Autumn of 2019, once the works are completed. The brilliant news is that we will be able to present exhibitions without having to worry about a leaking roof. Associated electrical rewiring will also reduce the fire risk in the museum.

Other works we are undertaking - unbeknown to most people as these are happening in our basement - are further electrical works and substantial improvements to our air conditioning systems. This includes the installation of new air conditioning equipment to replace old equipment which will make the museum much more environmentally sustainable.

We are undertaking these works, with kind support of Welsh Government, to protect the Welsh national collection. We constantly strive to improve the way we care for the three million objects housed at National Museum Cardiff. The collections allow us to refresh displays regularly and put on exhibitions with new themes – check out our new ‘People and Plants’ exhibition of the museum’s economic Botany collection. Collections are also used for research, study, teaching, commemoration and many other functions.

Hence, there are many reasons why we would want to do our best to preserve the collections as best we can. The maintenance works during the coming months will greatly assist us with our collection care and, if these occasionally impact on our public spaces, we do ask that you bear with us – the works are temporary but the benefits will be long-lasting.
