Conservation of finds unearthed by a badger

on Saturday, 16 April 2016. Posted in Archaeology, Conservation

You may remember the image of a group of ceramic sherds from one of our previous blog posts. Following reconstruction of the vessel we now have true understanding of the magnificence of the objects found. Watch a time-lapse video showing elements of the reconstruction of the vessel.

 

Conservation treatment involved a task like a jigsaw puzzle without a picture. The size, shape and colours of the sherds were used to determine their original location within the urn. Due to the uneven firing of the vessel and areas of burning caused by hot ashes being placed inside the vessel some areas were easier to piece together than others.

When the collared urn was originally manufactured ceramic technology was in its infancy with the kilns used never reaching the temperature required to permanently set the clay in position. During the time the vessel was in the ground, moisture from the surrounding earth also weakened the under-fired structure. This effect, on top of the unconventional excavation method, has meant that the overall shape of the vessel has become distorted.

Before reconstruction the edges of each fragment were strengthened by allowing a weak adhesive to be drawn into the rough surface to hold the loose and sometimes crumbling structure together. The adhesive is well used in conservation and has been developed and tested to ensure that it is long-term stable meaning it will not degrade causing damage to the original fragments of the vessel.

A stronger concentration of the same adhesive was used to adhere the fragments in position, small strips weak masking tape were used to hold the fragments in position as they dried. As the vessel was so large the reconstruction had to be undertaken in stages to ensure each level of fragments were securely in position and ready to support those placed on top.

The Stonehenge Visitor Centre's new Collection

on Tuesday, 26 November 2013. Posted in Conservation

As part of their contribution to the English Heritage update of the Stonehenge Visitor Centre Wiltshire Conservation Service have been conserving items from collections across the county.
Many of the items chosen for display at the new Stonehenge Visitor centre have previously been conserved; presenting the conservation staff with a range of challenges.


Many items have been sampled; that is sections of material have been removed and sent away for scientific analysis. Such analysis can help to identify the materials and methods used in manufacture, can date the object or help archaeologists and curators to learn what the object was used for. In the past greater amounts of material were required for reliable results to be achieved therefore large areas were damaged and the appearance of the objects dramatically affected. For example the Ox mandible, seen in images 1 & 2, where a large area had previously been removed for analysis dramatically affecting the profile of the bone. For display it was felt that this area should be reconstructed to show the true shape of the mandible.
