Textile conservators often use fabric supports to provide reinforcement for weak areas of a textile and to provide a visual infill in missing areas. The most common technique is to use dyed fabrics of a single colour but while a plain dyed support provides good reinforcement, it can be visually obtrusive when used with patterned or textured textiles. Two recent postgraduate dissertation projects at the Textile Conservation Centre (TCC) have experimented with hand printing and digital imaging techniques to alter the appearance of support fabrics so that they are less visually obtrusive and blend well with the colour and texture of the textile being supported. Case studies demonstrate the successful use of these techniques on a painted hessian rocking horse and a knitted glove from an archaeological context.","PeriodicalId":215333,"journal":{"name":"The conservator","volume":"51 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126077420","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is now established as a robust, valid and generally valued credential. With the second review of PACR having recently reported its findings, it is timely to reflect on how conservation's professional qualification fits both conceptually and practically in the wider arena of professional credentialling and validation in the United Kingdom and internationally. Such reflection suggests two broad conclusions. First, PACR withstands scrutiny in relation to the qualifying processes in other professions and in conservation internationally, and the designation Accredited Conservator‐Restorer (ACR) can be promoted with confidence as denoting a fully‐qualified, proficient conservation professional. Secondly, there is more that can be done to build bridges between entry‐routes into conservation and the achievement of accreditation, so that ACR status becomes a natural goal for those entering the profession.","PeriodicalId":215333,"journal":{"name":"The conservator","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122131331","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Designed to house the United Kingdom's growing national fossil collection, the building was intended to provide improved storage facilities and a suitable environment for the long‐term preservation of the collection. In 2000 an analysis of the storage environment and its effects upon the collections through the past thirty years concluded that the building, its functions and operating principles were directed at satisfying too many, and sometimes conflicting, requirements. In 2002 refurbishment commenced, aiming to correct many defects and to improve the quality of the collection environment. The collections and serials remained in situ, safely protected throughout the project. The health and safety of the staff and the safety of the collections were considered to be paramount during the work.

Mueck's sculptures painstakingly reproduce every detail of the human body down to individual hairs, veins and blemishes. Handling and transit of these works is complicated and risky. Once on display they are seldom protected and can readily suffer damage. Discussions with Mueck about his materials and techniques, working methodology and views on the preservation of his work are summarised. Polyester resin and silicone rubber samples were constructed and tested to predict the deterioration caused by light. A noticeable yellowing took place after the equivalent of 32 years in a museum. The results alerted the artist to the risk that the life‐like appearance of his sculptures could be markedly altered over time. The study, in rurn, highlights important conservation issues to be considered in creating, displaying and preserving contemporary works.","PeriodicalId":215333,"journal":{"name":"The conservator","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114609867","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
