Archeological material treated as part of the MSc Conservation Practise course at Cardiff University included waterlogged wood and leather, and iron objects.

A waterlogged treenail from the Newport Ship was treated using a two stage PEG treatment of PEG 400 and PEG 3350. The species of the wood was identified as alder using microscopic features. The analysis was carried out because the wood species affects the consentration of the solutions used during treatment. Freeze drying was used to dry the object.

The waterlogged leather fragments treated were excavated during restoration work in Bute Park, Cardiff. A bulk treatment was carried out on the multiple objects awaiting treatment.  The objects were cleaned mechanically and treated with EDTA to remove iron contamination. They were imbregnated with a glyserol/water solution and freeze dried.

The iron objects treated are small iron finds from excavation carried out in Ham Hill, an Iron Age hill fort. The objects were cleaned using air abrasion. Corrosion was removed until a magnetite layer was reached. Paraloid B-72 was used to consolidate some of the objects and to adhere pieces that had broken off.
