Cyclododecane (CDD), first introduced at Abydos by an American conservation team in 1999, was used to block-lift archaeological wood from 5000-year-old ships. Following this success, CDD became a mainstay of the conservation tool kit, commonly used to aid block-lifting in the field and allowed to sublime in the field lab. CDD-coated artefacts have also been sealed and packed to prevent sublimation, exploiting it to consolidate objects between seasons, and allowing treatments to be completed in subsequent years. This paper is a review of treatment methodologies using CDD in the field at Abydos and discusses both successes and failures. Database records indicate that CDD has been used over 50 times at Abydos over 17 years, representing perhaps the most extensive, long-term use of CDD on archaeological sites. A programme set up in 2011 to monitor lasting effects of CDD on the artefacts is discussed and possible alternatives to CDD suggested. Finally, recommendations for post-CDD treatment and artefact storage in the field are proposed.
