Webinar: Applying alkaline nanoparticles to deacidify alum-treated wood, 17 June 16:00 pm (GMT+1 London)

The Icon Book & Paper Group Committee are pleased to be able to bring you a series of live streamed talks while many people are required to stay at home during in these unprecedented times.

The next talk will be Susan Braovac & Fabrizio Andriulo giving their talk Applying alkaline nanoparticles to deacidify alum-treated wood.

Overview
Conservation of waterlogged archaeological wood using alum salts (potassium aluminum sulfate, ammonium aluminum sulfate) was a method used in the past to treat highly degraded wood. It was used on the Viking Age wooden finds from Oseberg, recovered in 1904 near Tønsberg, Norway. Today this wood is very acidic (pH ≤ 2), mainly due to the acid absorbed during the alum treatment. High acidity has caused the wood polymers to undergo a slow degradation over time. In order to slow down degradation, the research project Saving Oseberg investigates retreatment methods for these finds. In some cases retreatment cannot undergo water-based methods. For such objects, we are currently testing alkaline nanoparticles (calcium hydroxide in isopropanol) to deacidify the wood. We present a background of the alum method, facts about calcium hydroxide nanoparticles and show ongoing practical work using these.

About the speaker
Dr. Susan Braovac is an archaeological conservator in the research project Saving Oseberg (SO) at the Museum of Cultural History (2014-20). She has investigated the problems of alum-treated wood since the late 1990s. Dr. Fabrizio Andriulo is a conservation scientist who is a post-doctoral fellow in Saving Oseberg, and specializes in application of alkaline nanoparticles to acidic wood. Pia Kristina Edqvist is an archaeological conservator and joined the SO team in April 2020.

Webinar: «Sustainability and Cultural Heritage: Our Past and Our Future», 10 June 16:00 pm (GMT+1)

The Icon Book & Paper Group Committee are pleased to be able to bring you a series of live streamed talks while many people are required to stay at home during in these unprecedented times.

The next talk will be Caitline Southwick giving their talk Sustainability and Cultural Heritage: Our Past and Our Future

Overview
Sustainability is a global issue. As realities surrounding climate change and social injustice become more apparent and hit closer to home, people are ready to do something about it. But what does cultural heritage have to do with climate change? How do museums impact social justice? Why do conservators need to learn how to think green in their practice? This webinar will outline what sustainability means to cultural heritage and what unique opportunities the sector has to engage with and promote sustainability – resulting in holistic change and contributing to a sustainable future for all.

About the speaker
Caitlin Southwick (MSc, PD) is the Founder and Executive Director of Ki Culture and Sustainability in Conservation. She has over eight years of international training and experience in the conservation field. Her interest in sustainability derived from her personal passion for the environment and she believes strongly in the duality of conserving cultural heritage and the planet. She is a former professional member of the American Institute for Conservation’s Sustainability Committee and is the current Secretary of the Sustainability Working Group for the International Council of Museums.

Webinar Using online and open apps for preventive conservation, 27 may 16:00 pm (GMT+1)

The Icon Book & Paper Group Committee are pleased to be able to bring you a series of live streamed talks while many people are required to stay at home during in these unprecedented times.

The next talk will be Dr Josep Grau-Bove (Sustainable Heritage, University College London) giving their talk Using online and open apps for preventive conservation

Overview
Online apps for preventive conservation are proliferating in the web. For free and with a few clicks it is possible to analyse humidity and temperature data, estimate pollutant concentration indoors, predict dust deposition rates, and many other tasks, basic and advanced. Current research projects (such as the developments around IPERION-HS and ERIHS, the European Research Infrastructure for Heritage Science) will accelerate the creation of new online platforms and improve their capabilities. In this talk, I will provide an overview, with practical demonstrations, of some of the best available online tools, and present a blueprint for future developments.

Curso Online de «Conservación de patrimonio cultural en hierro», 30 abril-12 junio.

El Instituto del Patrimonio Cultural de España (IPCE), miembro de la PTI-PAIS, organiza la II edición del curso «Conservación de patrimonio cultural en hierro».

Este curso online se realiza con el fin de comprender los principios de alteración de las obras fabricadas en hierro, para poder minimizar el deterioro de este tipo de patrimonio y proporcionar una formación metodológica básica.

Para conseguirlo, además del conocimiento de los materiales constituyentes, debemos conocer el medio que los rodea y sus interacciones, así como el desarrollo del proyecto de intervención y las pautas de conservación preventiva.

Se ofertan 150 plazas.

La inscripción se llevará a cabo mediante el formulario disponible en la web del IPCE.
