Salts in display cases
Brief insight: The display cases in museums usually have a defined relative humidity in order to create optimal climatic conditions for exhibited objects. This can be influenced by various methods. These include electrical air conditioning devices, humidity buffers but also saturated salt solutions.
Looking for authors : Do you have any experience in the field of salts in display cases? If so, you can write a text or add new information and send it to firstname.lastname@example.org. We will then complete the article so it is available for all of our users!
SWBSS ASIA 2023 on September 20-22, 2023 in Nara, Japan
SWBSS is the conference series “Salt Weathering of Buildings and Stone Sculptures”, started in 2008. The conference aims at bringing together conservators, restorers, engineers, architects, academics, students and experienced researchers and to contribute thereby to the promotion of research and development within the field of salt weathering of porous materials.
Its previous series were held in Copenhagen (2008), Limassol (2011), Brussel (2014), Potsdam (2017), and Delft (2021). An idea of SWBSS ASIA as the conference series to be held in Asian countries was proposed at Potsdam in 2017 and its first meeting, SWBSS ASIA 2023, was announced at Delft in 2021. SWBSS ASIA 2023 was held at Nara, Japan, on September 20-22, 2023.

CRYSPOM VIII / 13-15 June 2023 in Ghent (Belgium)
The Biannual International workshop Crystallization in Porous Media CRYSPOM focuses on fundamental research of crystallization in porous materials. It unites researchers from geoengineering, geology, physics, chemistry, mechanics and conservation interested in crystal nucleation, growth and transport in porous media and its related consequences.
The idea is to bring together leading researchers and Ph.D. students to provide for a constructive and open dialogue. Also, it seeks to incite collaborations between theorists, modelists and experimentalists on an international level.CRYSPOM results from a long-standing tradition. The workshop was founded by Prof. Noushine Shahidzadeh in 2008 in Paris, and subsequently took place in Brienz (Switzerland, 2010), Troia (Portugal, 2012), Amsterdam (The Netherlands, 2014), Toulouse (France, 2016), Hamburg (Germany, 2018) and Pau (France 2021).
Workshop "Damaging salts in objects of cultural and architectural heritage"
September 11-15, 2023, Kartause Mauerbach near Vienna
INITIAL NOTICE WITH INVITATION TO REGISTRATION
Soluble salts are a serious threat to the existence of numerous objects of architectural heritage and cultural assets. The basis for the professional planning of measures is a fundamental understanding of the responsible damage factors and processes, which relates the latest scientific findings to the problems in practice. While specialist conferences and publications largely illuminate partial aspects of the topic, this workshop aims to provide first-hand basic knowledge of the behavior of soluble salts and the practical handling of object-specific analysis data in the concentrated working atmosphere of a three-day event. Although this usually does not mean that the problem has been solved, it is an essential prerequisite for planning suitable measures. The event consists of the 3-day workshop (module 1), which is followed by an all-day lecture event for a larger group of participants (module 2) and a day of excursions in Vienna (module 3). These modules can be booked together or individually.You can find more information [here].
