Athro'r Ardd

Hope all of you had a good Easter!

Now is time to show you one of the most interesting process in paper conservation, the washing treatment. But, can we wash a sheet of paper once it is already made?? Yes, we can. Before washing we have to keep in mind how the art work was made, such as the stability of the ink, damage to the paper, etc. I need to test EVERYTHING to make sure I don’t wash it all away!

We only do the washing if the paper need it. In the lithograph prints we found some dirt, tears, folds, creases, stains and foxing*. Washing them would remove the dirt, some stains and foxing and at the same time would re-forms the hydrogen bonds between the fibres, reinforcing the paper strength and improving the appearance too.

After this process, we deacidified the prints to neutralize the acidity in the paper with an alkaline solution. The alkali reserve will remain in the paper, ready to act against future acidification.

*Foxing: reddish-brown spots (the colour of a fox) over the surface of the paper which can be caused by a mold activity or a chemical reaction due to metal impurities in the paper.

Last week we created a storm in the galleries at National Museum Cardiff with our Easter workshops. Families who took part got to make their own pop-up landscapes inspired by John Constable’s Salisbury Cathedral from the Meadows 1831. This activity was part of the Aspire programme, funded by the Heritage Lottery Fund and the Art Fund.

Here are some of the mini masterpieces created.

We were impressed by the variety of skies! Some were stormy and brooding. Others filled with colour and light. Butterflies, bees, and a murder of crows all made an appearance – and, of course, some beautiful rainbows.

If Constable were alive today he surely would have approved! For him the sky was the most important part of a painting. It creates feelings, mood and emotions. I wonder what mood our families were in when they created theirs?

Whatever mood they were in at the time, they left the workshop feeling happy! Families were asked to complete the sentence ‘the workshop made me feel...’, and to hang it on our specially-created comments cloud. ‘Happy’ was the most popular response! Here are some others:

The workshop made me feel…

• Happy happy and I loved it a lot - Jack
• Interested because I like learning about Constable
• Hapus fel y gog achos rwy’n hoffi celf a chrefft
• Welcome ♥

Aspire

Salisbury Cathedral from the Meadows was purchased by Tate with assistance from the National Lottery through the Heritage Lottery Fund, The Manton Foundation, the Art Fund (with a contribution from the Wolfson Foundation) and Tate Members in partnership with Amgueddfa Cymru – National Museum Wales, Colchester and Ipswich Museum Service, National Galleries of Scotland, and Salisbury and South Wiltshire Museum, 2013.

To secure the painting, a unique partnership initiative was formed between five public collections: Tate Britain, Amgueddfa Cymru – National Museum Wales, Colchester and Ipswich Museums, Salisbury and South Wiltshire Museum and the National Galleries of Scotland. This initiative, named Aspire, is a five-year project supported by the Heritage Lottery Fund and the Art Fund enabling the work to be viewed in partner venues across the UK. National Museum Cardiff is the first venue to display the work.

Adrian Plant continues his fieldwork in the Amazon in collaboration with Jose Albertino Rafael and Josenir Camara from INPA (Brazil’s national Amazon research organisation) in Manaus.

So far two field-trips to remote corners of the Amazon have been successfully completed. The first was to Sao Gabriel da Cachoeira high up the Rio Negra not far from Brazil’s borders with Colombia and Venezuela and the second to a major tributary of the Amazon along the border with Peru at Benjamin Constant.

The forests of the Amazon Basin are flood forests; they become seasonally inundated by the flooded river and the waters bring with them many of the nutrients essential to the forests great productivity throughout the region. This year the forest remains unusually wet for the time of year which has caused a few practical problems for field entomology.- it is an acquired pleasure to slosh around in deep mud and water searching for new and interesting insects under a constant plague of biting mosquitoes. Yet, to an entomologist this is more or less a definition of “fun”!

The biodiversity is amazing of course and many of the insects seen and collected are undoubtedly new to science but will require much study in more comfortable surroundings after returning from the field. Meanwhile, Adrian will shortly be setting out on a third fieldtrip, this time to a little known area  between the mouth of the Amazon river and French Guiana where many exciting discoveries will undeniably be made.

Os oeddech chi yn ymweld â Llundain yr wythnos diwethaf mae’n siŵr eich bod chi wedi sylwi bod yr awyr yn llawn llwch – fel edrych drwy gwmwl brwnt! Ond beth yw mwrllwch, a beth yw’r gwahaniaeth rhyngddo â niwl?

Beth yw niwl?

Cwmwl ar y llawr yw niwl! Llawer o ddiferion dŵr mân yn hofran yn yr awyr yw niwl ac mae’n rhan naturiol o’r tywydd. Mae niwl yn helpu i ddyfrio planhigion ac yn ddiogel i chi ei anadlu i mewn.

Beth yw mwrllwch?

Llygredd aer yw mwrllwch. Mae’n cael ei gynhyrchu wrth i niwl gymysgu â mwg a nwyon cemegol ceir a ffatrïoedd ac mae rhai o’r cemegau yma’n wenwynig! Mae’n niweidio planhigion ac anifeiliaid a gall fod yn beryglus ei anadlu i mewn.

Mae’r mwrllwch diweddar yn Llundain yn gymysgedd o niwl, llygredd a thrydydd cynhwysyn – tywod o’r Sahara! Anialwch anferth yn Affrica yw’r Sahara ac mae peth o’r tywod yno yn fân iawn, iawn fel llwch. Weithiau bydd stormydd gwynt yn codi’r llwch a’i chwythu filoedd o filltiroedd i’r DU. Dyna siwrnai hir!

Yn anffodus, mae’r gymysgedd o niwl, llygredd a llwch yr anialwch yn golygu bod mwrllwch Llundain yn niweidio’r ysgyfaint, ac mae wedi gwneud rhai pobl yn sâl. Mae mwrllwch yn un rheswm da iawn pam y dylen ni i gyd geisio lleihau llygredd aer!

Beth alla i ei wneud i leihau llygredd aer?

Meddyliwch am lygredd aer… beth sy’n ei achosi? Allwch chi feddwl am 3 pheth y gallech chi ei wneud i leihau llygredd aer? Trafodwch yn y dosbarth cyn gwirio eich atebion yma (gwefan Saesneg).
