A few years ago the chemical works BP Baglan Bay called me and said they were clearing out the offices as the site was closing and would I like to see if the museum wanted any objects for our Modern Industry collection?

I couldn’t wait to go and have a look, and as there was quite a lot to go through I took our museum van in the hope of a few accessions.

There were lots of photographs, some in frames, some big aerial photos too. There were overalls, hats and jackets with logos on them – just the sort of things that tell a great story when exhibited for displays.

There were tools specific to the industry and other bits and pieces like signs and gauges.

I loaded a few things in the van to take back to the museum so I could go through them to decide what we would like to keep and what should be returned.

But as I was about to leave they called me back and asked if I wanted the paintings? I hadn’t noticed these as they were covered in bubble wrap and stood against a wall.

One of the paintings was quite big, about 4’6”x 6’ (1.5 x 2.1m) and I couldn’t see the subject for the wrapping. The other was much smaller about 2’ x 2’6” (0.6 x 0.76m). I was told the bigger one was an oil painting of Baglan Bay at Night and the smaller one a watercolour of a power station. I put them in the van, got the paperwork signed and left for our stores in Nantgarw where I could spread things out and examine them properly.

About a week went by and I still hadn’t looked at the paintings as I had been going through all the other objects first.

When I did take the bubble wrap off I was really surprised by the quality of both paintings. The oil painting was really striking and the BP staff had told me that it had hung in the office since the 1960s.

I looked for a painter’s signature and then the real surprise hit me! In the bottom corner was ‘Vicari’.

Bells rang deep in my head, where did I know that name from? A quick internet search answered that. The richest living artist in the world. The official Gulf War artist. Artist to the Saudi Royal family. And born in Port Talbot. This fitted my collecting policy perfectly, being an industrial scene in Wales painted by a Welsh artist. The only snag from my point of view was that it could be quite valuable and BP might want to keep it.

I contacted them straight away and told them about the artist and its possible value. One of their directors, David, called me and told me that they were happy it would be going to the National Museum of Wales and he couldn’t think of a better place for it.  This generosity meant that we could save a national treasure for future generations.

So far we had treated the painting as if it were a genuine ‘Vicari’, but was it really?

I contacted the ‘Vicari’ website and sent them an image of our painting asking them if they could confirm if Andrew had painted it.

I checked my email every day. No replies. How else could we confirm this if they didn’t get back to us?

One sunny morning about three weeks later my phone rang. I could tell from the number it was someone in France calling. This was not unusual as we have many visits from French schools and as my schoolboy French is just about good enough to get by, my number was very often given to schools as a contact.

After answering with who I was, a deep, rich voice said:

‘Ah, Andrew here, I hear you’ve found the lost Vicari’

I couldn’t believe it! Andrew Vicari calling me from his home in France! To say I was flabbergasted is an understatement!

Andrew told me he had painted Baglan in the early 1960s and was really glad of the commission at the time (when he wasn’t so well known). We spoke for about half an hour about all sorts of things and he went on to tell me an incredible  story from 1966.

Andrew had painted a picture that was to be auctioned for the Aberfan Disaster Appeal and went along to the auction in Cardiff. Before it got underway, two burly men approached Andrew and said someone needed to talk to him in private. He was shown to a room and waiting there were two more men in sharp suits, looking a bit ‘dodgy’ (his words). These two told him they wanted to buy the painting, and asked how much did he want for it? He told them that it wasn’t his to sell as he’d given to the appeal and it was out of his hands. They kept on that they wanted it and he needed to get it for them. They were getting more and more insistent. After repeating that he couldn’t a number of times, they finally left, to Andrew’s relief.

It turned out that they were the Kray twins! He laughed ‘I’m one of the few people to have said ‘no’ to the Kray twins and lived to tell the tale!’

He told me that he was very happy his painting was going to be in the National collection and that he would do anything for Wales!

We never had the chance to speak again; sadly Andrew died in Swansea, in 2016 aged 84. It’s lovely that we have such incredible paintings to remember him by.

This story happened in 2009 and the painting has been in our stores in Nantgarw where is has been conserved and a new glazed frame made. We’ve been waiting for a chance to exhibit it and finally it will happen.

You can see the painting as part of an Andrew Vicari exhibition from 13^th July to 3^rd November 2019 at the National Waterfront Museum, Swansea.

Mae’n fis Mehefin ac rydym wedi dewis silicon i fod yn elfen y mis. Efallai na fyddai rhywun yn meddwl yn syth bod i silicon arwyddocâd arbennig i Gymru, ond mae iddo hanes diddorol.

Mae silicon (symbol cemegol – Si, rhif atomig – 14) yn solid crisialog caled ond brau, sydd â sglein metalig llwydlas. Silicon yw’r elfen fwyaf cyffredin ond un (tua 28% o ran màs) yng nghramen y Ddaear. Ocsigen yw’r elfen fwyaf cyffredin ac mae i’r ddwy elfen affinedd cryf. O ganlyniad i hynny, cymerodd tan 1823 i wyddonydd – Jöns Jakob Berzelius – baratoi silicon yn ei ffurf bur.

Yng Nghymru, mae silicon i’w gael ym mhobman bron ar ryw ffurf neu’i gilydd: o gwarts (silicon deuocsid, SiO₂) mewn tywodfeini, amryfeini a cherrig silt gwaddodol; i silicadau cymhlyg mewn creigiau igneaidd a metamorffig; a gwaddodion mewn priddoedd.

Bu silica (silicon deuocsid, neu gwarts) yn cael ei gloddio’n helaeth yn ardal Pontneddfechan, de Powys, o ddiwdd y 18^fed ganrif tan 1964 a’i ddefnyddio i wneud brics tân ar gyfer odynau a ffwrneisi. Mae’n digwydd ar ffurf deunydd pur iawn o ddwysedd uchel mewn cwartsit mewn uned ddaearegol o’r enw Grutfaen Gwaelodol neu Dywodfaen Twrch. Wrth i’r cwartsid gael ei hindreulio a’i erydu, gadawyd dyddodion o dywod silica a gafodd ei gloddio'n helaeth i wneud brics tân gwrthsafol ar gyfer y diwydiannau mwyndoddi.

Yn y gogledd, bu masnach weddol ddi-nod mewn creigrisial – math di-liw, tryloyw o grisial cwarts – yn Eryri yn ystod y 18^fed ganrif a’r 19^eg ganrif wedi’i chanoli o gwmpas pentref Beddgelert. Mae T. H. Parry-Williams yn cyfeirio at hyn yn un o’i Ysgrifau.  Roedd mwynwyr a thywyswyr mynydd yn chwilota am wythiennau cwarts yn y mynyddoedd ac yn casglu crisialau i’w gwerthu i dwristiaid. Mae’n bosib bod rhai wedi'u defnyddio i wneud canwyllyrau crisial. Yn ddiweddarach, câi crisialau eu canfod yn achlysurol yn y chwareli llechi enfawr neu wrth fynd ati ar raddfa fawr i greu lonydd ar dir fforestri yn yr 1960au.

Mae silicon, ar ffurf silica (enw arall am silicon deuocsid) yn bwysig i rai organebau hefyd, yn enwedig ddiatomau a sbyngau.

Algâu microscopig ungellog sydd â chellfur cymhlyg wedi'i wneud o silica yw diatomau. Maent i’w cael yn helaeth ym mhob math o ddŵr, maent yn cynhyrchu ocsigen a chânt eu bwyta gan organebau eraill yn y dŵr. Yn aml, defnyddir diatomau i fonitro ansawdd dŵr.

Mae sbyngau’n adeiladu eu sgerbydau o fframwaith o elfennau bychan, bach o’r enw sbigylau. Yn y rhan fwyaf o grwpiau o sbyngau, gwneir y rhain o silica.  Ymhlith yr enghreifftiau harddaf mae sbwng gwydraidd Cawell Gwener, sy’n byw wedi’i angori wrth wely’r dyfnfor ger y Philipinau.  Mae pâr o berdys yn byw y tu mewn i’r sbwng, gan baru y tu mewn a threulio’u holl fywyd wedi’u gwarchod oddi mewn i’r waliau gwydraidd cain.  Diolch i’r berthynas symbiotig anghyffredin hon, mae sgerbydau marw Cewyll Gwener yn anrheg briodas boblogaidd yn Japan.

Sbyngau yw’r math mwyaf cyntefig o anifail ar y Ddaear, ac mae eu sbigylau gwydn yn ymddangos fel ffosilau yn dyddio o hyd at 580 miliwn o flynyddoedd yn ôl. Yn ogystal, mae silica’n chwarae rhan bwysig yn gwarchod mathau eraill o ffosilau.  Pan gleddir anifeiliaid neu blanhigion marw, gall silica o ddŵr daear lenwi’r mandyllau a mannau gweigion eraill mewn pren, esgyrn neu gregyn, a/neu gall gymryd lle’r deunyddiau gwreiddiol wrth iddynt bydru neu hydoddi.   Mae hyn yn digwydd amlaf mewn ardaloedd lle mae llawer o silica yn y dŵr daear, oherwydd gweithgaredd folcanig neu am fod creigiau ac ynddynt lawer o silica wedi erydu.   Mae’r olion organig yn ganolbwynt ar gyfer ffurfio deunyddiau silica, ac yn aml mae’r graig sydd o gwmpas y ffosilau wedi’i gwneud o fwynau gwahanol.  Er enghraifft, wrth i gregyn a wnaed yn wreiddiol o galsiwm carbonad hydoddi, gall silica gymryd lle’r calsiwm carbonad, a chânt eu ffosileiddio mewn calchfaen (calsiwm carbonad).  Mae’n hawdd tynnu’r ffosilau trwy roi’r graig mewn asid a disgwyl iddi hydoddi, gan adael y ffosilau a siliceiddiwyd ar ôl.  Yng nghasgliadau ffosilau’r Amgueddfa, ceir llawer o gregyn wedi’u siliceiddio – braciopodau, amonitau, bryosoaid a chreaduriaid morol eraill.

Un o’r mathau mwyaf trawiadol o ffosil a siliceiddiwyd yw ‘pren petraidd’.  Daeth silica i gymryd lle celloedd gwreiddiol y pren wrth iddo bydru ac i lenwi unrhyw fylchau, gan ei ‘droi’n garreg’ yn llythrennol.  Mewn rhai mannau, yn cynnwys Patagonia a'r Unol Daleithiau, gwelir bonion coed cyfan lle disodlwyd y pren gan silica yn yr hyn a elwir yn ‘fforestydd petraidd’.  Ceir planhigion eraill, fel conau, wedi’u ffosileiddio fel hyn hefyd.

Craig a wneir o grisialau bach iawn o silica yw cornfaen neu siert.  Ffurfiwyd llawer o ddyddodion cornfaen mawr ar waelod cefnforoedd hynafol o ‘forlaid silicaidd’, a wnaed o sgerbydau miliynau o organebau bach iawn yn cynnwys diatomau a rheiddiolion (plancton ungellog).  Gall cnepynnau cornfaen ffurfio oddi mewn i greigiau eraill hefyd trwy brosesau cemegol.   

Gelwir cornfaen sydd mewn sialc yn fflint, a bu’n ddeunydd pwysig iawn ar gyfer gwneud tŵls yn y cyfnod Cynhanesyddol. Gwneir y tŵls trwy naddu’r fflint, hynny yw trwy daro ymyl y fflint sydd wedi’i baratoi, neu lwyfan taro, â charreg galetach er mwyn rhyddhau darnau o’r enw naddion neu lafnau.  Yna, gellir addasu’r naddion neu’r llafnau hyn ac, yn wir, y craidd y cânt eu taro ohono a’u gwneud yn dŵls cywrain. Ymhlith y rhai mwyaf cywrain mae pennau saethau main, yn cynnwys y rhain o fedd o’r Oes Efydd yn Breach Farm, Bro Morgannwg. Gan amlaf, fflint oedd y dewis cyntaf ar gyfer gwneud offer torri miniog am fod ei raen mor fân a’i fod yn hollti’n gregynnaidd ac yn lân i roi ymyl dorri finiog iawn. Yn wir, i’r fath raddau nes bod straeon am lawfeddygon y llygad yn defnyddio llafn fflint newydd ei dorri i drin llygaid cleifion weithiau!

Gan fod graen mân iawn i gornfaen a’i fod yn galed iawn, gall ddal ffosilau o bethau bach iawn o gyfnod pell iawn yn ôl yn hanes ein planed.  Credir mai mewn cornfeini y ceir y ffosilau hynaf ar y Ddaear, ac maent yn cynnwys olion posibl bacteria dros 3 biliwn o flynyddoedd oed.  Mae ffosilau iau, o Gornfaen Rhynie o ogledd yr Alban, yn rhoi cipolwg i ni ar un o’r cymunedau cynharaf ar dir, 400 miliwn o flynyddoedd yn ôl.  Cadwyd manylion cywrain planhigion ac anifeiliaid syml, yn cynnwys creaduriaid cyntefig tebyg i gorynnod, a sgorpionau, diolch i ddŵr llawn silica o ffynhonnau folcanig poeth.

Math hydradol o silica yw opal, sy’n golygu ei fod yn cynnwys rhwng 3 a 21% o ddŵr.  Yn wahanol i silica arferol, nid oes iddo ffurf crisialog penodol, ond mae rhai o’i ffurfiau’n diffreithio goleuni, gan greu effaith symudliw hardd mewn nifer o wahanol liwiau.  Am y rheswm hwn, mae opal wedi’i werthfawrogi ers canrifoedd fel gem ar gyfer gwneud tlysau crog, modrwyau a mathau eraill o emwaith.  O Awstralia y daw llawer o opal y byd, ac fe geir yno ffosilau prin ac ysblennydd wedi’u hopaleiddio hefyd.  Daeth opal i gymryd lle cregyn infertebratau fel belemnitau (creaduriaid cynhanesyddol tebyg i fôr-lewys [squid]), a hyd yn oed esgyrn deinosoriaid, gan greu sbesimenau lliwgar iawn mewn byd lle mai llwyd neu frown yw ffosilau gan amlaf.

Mae Riley, ddisgybl yn Ysgol Stanford in the Vale, wedi cymryd rhan yn yr ymchwiliad Fylbiau'r Gwanwyn i Ysgolion am y tair blynedd diwethaf. Mae wedi dangos ymrwymiad arbennig i'r prosiect, ac mae wedi gwneud argraff fawr ar gydlynydd y prosiect drwy ei adborth disgrifiadol a chyfeillgar. Mae'n rhaid i mi ddweud, rhwyf wedi mwynhau darllen diweddariadau wythnosol gan Riley dros y tair blynedd diwethaf.

Dyma rai o sylwadau gorau Riley:

2017:

• The weather has turned really cold today. Been training people to do this experiment during the week. From Riley xxx
•  Hello. This week it has not been icy and it has been nice all except today. Hope you have had a nice week. Bye Bye (Riley)
•  Hello, this week it has been cold and hot and it has been a really good week because we have had a delivery of two new trolleys and we even invested in a wormery which is a big hit with our foundation friends. (Riley)

 2018:

• Hi this is Stanford in the vale primary school, we done this amazing project last year .I am Riley one of the gardening club members. I was the one that recorded and submitted this data last year. I loved doing this project last year, I hope I will this year too. I will be also teaching some of my friends how to do this project this year too. Bye Bye Riley (Riley)
•  Cannot believe this is the last weather reading for this year! We have observed some strange weather patterns this year! Snow - sunshine! (Riley)

 2019:

• Happy to restart the project and I am teaching the younger children in the club how to record. Have a good weekend and we will be back next week. Regards Riley (Riley)
• HI THERE, this week it has been a mixed week and there has been a lot of rain this week and there has been a bit of sun. Today in class we were talking about global warming which is a serious issue which needs to be sorted out. Speak to you next week!

I ddathlu cyfraniad Riley i'r prosiect, fe ofynnon ni a fyddai'n hapus i ateb rhai cwestiynau a rhoi cipolwg i ni o'i brofiad o gymryd rhan yn yr ymchwiliad.

Cyfweliad gyda Riley:

Q. How long have you been involved with the Spring Bulbs for Schools Investigation?

A. I have been involved in this investigation for three years now.

Q. What have you enjoyed most about the project?

A. I’ve mostly enjoyed recording the weather and the rain. I like seeing the difference between the temperatures of different days.

Q. What do you feel you have gained from the project, have you developed new skills?

A. Yes, I do think I have gained on this project. I have developed how to record the rain using a gauge and it has helped me using a thermometer more accurately.

Q. What are your thoughts on Science and Maths?

A. I am quite interested in both of these subjects, so this has helped me produce a lot more in these subjects.

Q. What were you feelings towards these subjects before the project, have they changed?

A. I was feeling quite confident before I started and now I am feeling much more confident about it.

Q. Were you aware that you were doing math and numeracy during the project?

A. I was sort of aware that I was using maths and numeracy during the project. I was mostly aware as I was measuring in millimetres and degrees.

Q. Were you confident taking scientific measurements before the project?

A. I was a little confident but I wasn’t that sure on it but now I am really happy about it.

Q. Do you feel these skills have developed through your time on the project?

A. Yes definitely, before I wasn’t that sure mostly on how to measure the rain and this project has developed my skills on that and developed my skills also in science.

Q. What advice would you give us to improve or develop the project?

A. I think it would be good fun if you could give the children some more fun activities or competitions because at the moment you don’t have many.

Q. You took a leading role, teaching other pupils about the project. Can you tell us a little bit about that experience?

A. I think it is really fun / exciting teaching other children about this experiment because it makes me feel like it is helping other children develop their science / maths and it makes me think that they could take over the job and become future scientists! 

Rydym wedi cymryd cyngor Riley, a byddwn yn edrych ar weithgareddau a chystadlaethau newydd y gallwn eu cyflwyno dros y blynyddoedd nesaf.

Riley yw'r cyntaf i gael ei henwebu fel Pencampwr Bylbiau'r Gwanwyn. Yn y dyfodol, byddwn yn gofyn athrawon i enwebu disgyblion sydd wedi dangos ymrwymiad rhagorol neu wedi datblygu fel canlyniad o'r prosiect, i gael eu cydnabod fel Pencampwr Bylbiau'r Gwanwyn.

Diolch Riley, a phawb a gyfranogodd i'r prosiect eleni.

Athro’r Ardd

Here at the National Museum Cardiff, we have several display trolleys of many different kinds. However in this blog, I wish to talk about the flashcard card game featured on our art trolley named Guess the Artist. In this particular game visitors to the museum can sit down with family members and friends inside in the gallery. The idea behind the game is that many artists are enclosed on cards within the box, along with pictures and captions written on each side of the card giving information about the artist and other relevant facts. 

For example, one of the display cards has pictures of works by Vincent Van Gogh. On one side of the card are pictures which you can use to guess the artist’s identity, and on the other side are written captions along with the artist’s name. Families can play the game for several minutes guessing the various different artists on the cards. 

This is particular game is excellent for our many visitors because after finishing the game, they can go in search of the various artworks from the cards, some of which are on display in the museum’s many galleries. This is fantastic for families and a brilliant educational process for all involved.

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.
