After-excavation care at Amara West

Salt crystals on the rim of beer jar C8008

I visited the stores where we keep the objects excavated from the site, to check they were in good condition. Objects from a site like this one often contain salts that could damage them, so I wasn’t surprised to observe that several objects had salt crystals on them, particularly the pottery and some stone sculpture.

The artefacts retrieved at Amara West are subject to environmental conditions which include high humidity and salinity, the result of the site’s proximity to the Nile. Ceramic and stone buried in soil absorb the salts present in the deposits.

Beer jar C8007 after desalination this week

Following my advice, and discussions with Marie Millet and Neal Spencer, two beer jars from grave 201 were chosen for treatment, as they were affected by salt, with a thick visible layer of white concretions.

The salts are harmful and are not only an aesthetic issue; they obscure the object’s surface and can lead to surface exfoliation – the surface lifting off. Eventually, the crystallisation of salts can lead to disintegration.

The most efficient way to extract salt consists of soaking the objects in water over a long period of time, though extra steps need to be taken with fragile objects, or those bearing paint.

The removal of soluble salts can be a very lengthy procedure. In this case, the jars were bathed repeatedly in plenty of warm water for a period of eight days with the water being changed every day.

Unfortunately, no distilled or deionised water and conductivity meter (to measure the decreasing level of salt) is available here. Nonetheless, soluble salts appear to have completely disappeared from the jars, ensuring their long-term preservation.

Looking to future seasons, we might consider testing salt levels in the local river water, which is used for washing all pottery prior to study, recording and storage.

Edward Burne-Jones was born #onthisday in 1833. This watercolour from his ‘Flower Book’ is titled ‘White Garden’. This was a name for Atriplex hortensis, a small garden plant that has edible leaves. In this painting Burne-Jones has created an imaginary ‘white garden’, populated with lilies that are being picked by two white-clad angelic figures. Like other figures in his works, they appear dressed in classically inspired white robes, with their blonde hair tied back.
#EdwardBurneJones #BurneJones #PreRaphaelite #flowers In this second watercolour from the ‘Flower Book’ of Pre-Raphaelite artist Edward Burne-Jones, we can see the goddess Venus walking through the night’s sky with doves. This painting is titled ‘Rose of heaven’ – a name given to the plant campion, a small pink flower. Burne-Jones took inspiration from the name of the flower and its connotations, rather than what the flower actually looks like. The depiction of Venus seems to be heavily influenced by Botticelli’s ‘Birth of Venus’, with flowing blonde hair and a dynamic pose.
#EdwardBurneJones #BurneJones #PreRaphaelite #flowers To mark the birthday of Pre-Raphaelite artist Edward Burne-Jones (1833–1898) this week, we’re featuring paintings from his ‘Flower Book’ – a sketchbook full of watercolours and drawings that contained fantasy artworks inspired by the names of flowers. This painting is titled ‘Love in a tangle’ – a name sometimes used for the climbing plant clematis. The scene suggests the story of Ariadne, who gave Greek hero Theseus a ball of golden thread to unwind as he wandered through the labyrinth in search of the minotaur (a mythological creature – half-man and half-bull). Here she waits anxiously for her lover to follow the thread back out of the maze. The clematis and its maze of tangled foliage inspired Burne-Jones to represent this story from ancient Greek mythology in his Flower Book.

The Museum’s Montague Place entrance is just as grand as the more-visited Main entrance on Great Russell Street. This part of the Museum contains the King Edward VII galleries, and the foundation stone was laid by the King in 1907. This side of the building was designed in the Roman style rather than the Greek Revival of Great Russell Street. It features numerous imperial references, including the coat of arms above the door, and sculptures of lions’ heads and crowns. The architect Sir John James Burnet was knighted for his work designing these galleries, and the building was opened by King George V and Queen Mary in 1914 (Edward VII had died in 1910). #regram #repost #architecture #BritishMuseum #lion Another brilliant photo of the Museum’s Main entrance on Great Russell Street – this time by @violenceor. The perspective gives a good sense of the huge scale of the columns. The Museum has two rows of columns at the main entrance, with each being around 14 metres tall and 1.5 metres wide. Designer Sir Robert Smirke used 44 columns along the front elevation. This design of putting columns in front of an entrance is called a ‘portico’, and was used extensively in ancient Greek and Roman buildings. #regram #repost #architecture #neoclassical #BritishMuseum The Museum looks spectacular with a blue sky overhead – especially in this great shot by @whatrajwants. You can see the beautiful gold flashes shining in the sun. This triangular area above the columns is called a ‘pediment’, and was a common feature in ancient Greek architecture. The copying of classical designs was fashionable during the late 18th and early 19th centuries, and was known as the Greek Revival. The sculptures in the pediment were designed in 1847 by Sir Richard Westmacott and installed in 1851. The pediment originally had a bright blue background, with the statues painted white. #regram #repost #architecture #neoclassical #sculpture #gold #BritishMuseum
