Museum Conservation Services Ltd assessed the six parchment documents belonging to the Town Council of Higham Ferrers:
Charter of 1556, Philip and Mary
Charter of 1604, James I
Byelaws of 1616, James I
Charter of 1664, Charles II
Charter of 1684, Charles II
Charter of 1886, Victoria.
Their report showed:
the storage materials and method were slowly causing chemical and physical damage to the documents
previous conservation work was of a basic level and had unfortunately caused problems of its own.
Conservation work began in September 2018 and took nine months to complete.
The process aimed to restore any damage caused by age and poor storage. The conservators used their own discretion as to how much repair work to carry out so as not to lose authenticity.
Light in the studio is controlled to preserve materials in good condition.
Specifically designed artificial lights and treated windows are installed to eliminate damaging UV light.
To lessen the ‘waves’ or rucks in the parchment, charters are hydrated with mist. They are too delicate to be stretched and can only be air dried. This process may have to be repeated several times.
This document is stronger than earlier charters and has been restored using the hydration and stretching method.
The document is hydrated with vapour and the pegged out to a board which is tightened between each treatment to ease any ‘waves’ in the material.
Sometimes UV light in a darkened room will reveal hidden damage – for instance the 1556 Charter revealed a faded portrait of both Phillip and Mary which cannot be detected by the naked eye.
the restored original Charters are now stored in boxes created from acid-free material to eliminate any further damage and stored in safe conditions at Northampton Record Office whilst remaining the property of Higham Ferrers Town Council
digital images of the restored Charters are displayed on this website
framed full-size prints of the Charters, alongside interpretative material, formed part of a touring exhibition in the town and wider area in Summer and Autumn 2019
the town celebrated the restoration of the Charters on the Charter Celebration Day – Saturday 29 June.
