Prof Magdalena Sobon from Poland and Michael Jackson Blebo from Ghana shared their expertise with staff and students during their visit to the Department of Fine Arts at the University of the Free State.
In a concerted effort to solidify its identity in South Africa and abroad, the Department of Fine Arts at the University of the Free State (UFS) recently played host to two distinguished artists: Prof Magdalena Sobon from the Wladyslaw Strzeminski Academy of Fine Arts in Lodz, and the Ghanaian multidisciplinary artist, Michael Jackson Blebo.
Dr Adelheid Von Maltitz, Senior Lecturer in the Department of Fine Arts at UFS, lauded the visits, held between 19 and 29 March 2024, as an enriching learning experience for the faculty and students within the department.
The visit highlights
During their visit to UFS, Prof Sobon and Blebo actively engaged with the department’s staff and students. Prof Sobon, an acknowledged paper-making artist, conducted a comprehensive two-day workshop, imparting extensive knowledge in this craft. As a direct outcome of this workshop, the department has procured the requisite equipment and materials, enriching the students’ capabilities in this medium. Blebo on the other hand, conducted a demonstration on clay bust modelling and both artists participated in critique sessions with the fourth-year students. Dr Von Maltitz underlined the significance of Blebo’s African heritage, noting, ‘’For our students to interact with a young, accomplished artist of his calibre is of benefit to them in terms of how they may envision their art careers.’’ Of particular note were Prof Sobon’s interactions with the students, wherein she shared her own artistic practices from her student years during her lectures.
In addition to their engagements with the students, Prof Sobon and Blebo also had the opportunity to present their research to second-year sculpture students at the Richmond Land Art Project, an off-campus initiative fostering art creation centred on socio-economic and other pertinent issues.
Future collaborations
Dr Von Maltitz emphasised the importance of maintaining ties with these eminent artists for the department’s growth and global outreach. Prof Sobon’s visit has paved the way for two department members to visit the Wladyslaw Strzeminski Academy of Fine Arts in Lodz in the near future. ‘’These individuals will get an opportunity to learn about studio setups and network with fellow academics, creative researchers, and artists,’’ stated Dr Von Maltitz. She hailed the visit by the two artists as both stimulating and fruitful, particularly for the students.
Prof Tredoux turns theories regarding the formation of metals on its head

The latest research conducted by Prof Marian Tredoux of the Department of Geology, in collaboration with her research assistant Bianca Kennedy and their colleagues in Germany, placed established theories regarding how minerals of the platinum-group of elements are formed, under close scrutiny.
The article on this research of which Prof Tredoux is a co-author – ‘Noble metal nanoclusters and nanoparticles precede mineral formation in magmatic sulphide melts’ – was published in Nature Communications on 6 September 2013. It is an online journal for research of the highest quality in the fields of biological, physical and chemical sciences.
This study found that atoms of platinum and arsenic create nanoclusters, long before the mineral sperrylite can crystallise. Thus, the platinum does not occur as a primary sulphur compound. The research was conducted at the Steinmann Institute of the University of Bonn, Germany, as well as here in Bloemfontein.
Monetary support from Inkaba yeAfrica – a German-South African multidisciplinary and intercultural Earth Science collaborative of the National Research Foundation (NRF) – made this research possible. Studies are now also being conducted on other metals in the precious metal group, specifically palladium, rhodium and ruthenium.
The discovery of the nanoclusters and the combination with arsenic can have far-reaching consequences for the platinum mine industry, if it can be utilised to recover a greater amount of platinum ore and therefore less wastage ending up in mine dumps. This will signify optimal mining of a scarce and valuable metal, one of South Africa’s most important export products.
For Prof Tredoux, the research results also prove thoughts she already had some twenty years ago around the forming of platinum minerals. “Researchers laughed in my face, but the evidence had to wait for the development of technology to prove it.” Young researchers were very excited at recent congresses about the findings, since the new models can bring new insights.
“Chemistry researchers have been talking about platinum element clusters in watery environments for quite a while, but it was thought that these would not appear in magmas (molten rock) due to the high temperatures (>1 000 degrees celsius).”
Prof Tredoux has already delivered lectures at congresses in Scotland, Hungary, Sweden and Italy on this research.
