Icon Archaeology Group Emerging Professionals Webinar
To: Tuesday 08.12.20
Online via Zoom
The Icon Archaeology Group is hosting a webinar for emerging professionals to present projects and research related to archaeological conservation that have allowed them to expand a particular skill or knowledge area.
This online event is an opportunity for students and early career professionals to increase their confidence in presenting ideas, in a friendly setting, and a chance for you to hear about the following research and projects.
Processing Fused Deposition Modelled (FDM) polymer surfaces with heat, abrasion, solvent, and filling to reduce the appearance of corrugation and create visually integrated removable infills in low-fired ceramic objects
This study assessed methods of processing the surfaces of Fused-Deposition-Modelled (FDM, 3D printing) polymers with the goal of reducing the corrugated appearance that is often a feature of 3D printed objects. The aim was to create a surface upon which paint could be applied in order to establish the suitability of these 3D-printed polymers for use as infills in low-fired ceramic heritage objects. Two phases of testing were employed; the first compared four methods of processing the sample surfaces, using microphotography, gloss meter readings, and a touch test. The second dealt with the adhesion rates of the applied paint layer and painting samples to mimic low-fired ceramics. During phase one, the processing methods used were heat, abrasion, solvent, and filling. Heat processing was unsuccessful, but the other methods effectively reduced the corrugation. During phase two, a cross-cut tape test was used to assess the adhesion rates of the paint layer. This showed that the solvent and abrasion methods had the highest rates of adhesion. It was concluded that the solvent method was the most effective due to the ease of treatment and the high paint adhesion rates.

New lines of research on archaeological bone
Bone is one of the most abundant materials in the archaeological record; nevertheless, conservation research has focused very little on this material. Taphonomic processes act over a long period of time, compromising the state of conservation and future study. In this presentation, the lines of research that are being initiated at IPHES (Tarragona, Spain) on the cleaning and consolidation of this type of material will be presented. Through study of the surfaces with 3D digital microscopy, before and after cleaning, the effects of different tools in the mechanical cleaning process may be analysed. As for consolidation, we have studied the viability of this treatment in humid environments and the effectiveness of different consolidants, focusing mainly on their penetration capacity in archaeological bone. In addition, other products, such as calcium hydroxide, infrequently used in bone conservation, are being explored. From both lines of research, the aim is to improve the knowledge of these treatments on archaeological bone.

What I learned: the importance of communicating conservation to non-conservation professionals
Two concealed leather shoes were discovered in the foot of a staircase in an eighteenth-century warehouse during works to convert the building into offices in 2017. They were removed by builders and eventually made their way to me via the project manager. I carried out conservation treatment on the shoes, identifying materials, construction and their approximate age. I cleaned and created storage for the shoes, and carried out research into concealed garments in buildings. This formed the basis of my MA report at the University of Lincoln. However, the biggest lesson was the need to advocate for cultural heritage, both tangible and intangible. With the project manager and contractors the need to communicate conservation principles was explored, in order that non-conservation professionals could be made aware of concealed objects, and that a reporting mechanism could be set up so that future finds could avoid damage or loss of context. This was successful and other objects were reported and removed during the project, including a flag, a record book of circa 1923 and lots of rags. With senior management, the superstitions and beliefs around concealed garments were addressed, including the question of whether the shoes should be reinstated in the new building.

The investigative conservation of two composite pistols from the Rooswijk shipwreck
Composite objects often present the conservator with a number of dilemmas. This talk seeks to outline the decision-making process in the investigative conservation of two concreted composite pistols from the Rooswijk wreck. The talk will include discussion of the research and practical approaches to conservation considered prior to intervention.
We warmly invite you to join us by registering at https://us02web.zoom.us/webinar/register/WN_XYLNVUInRpCacuZWL04I_w.
We welcome conservators and heritage professionals at all levels to come and listen to our speakers. There will also be time for questions.
