TC23: Education

The main focus of our activities is the organization and support of workshops, among which are the Montpellier Research Student Workshops held in July each year, and the workshops that make up the “Clear as Glass” series, held during the DDG annual conferences in Germany. An International Training Team is also available and recently has organised focussed training events in South America. Additionally, plans include the updating of the ICG Book List, a compilation of available courses on glass and input into the Wikipedia pages on Glasses.

Activities of TC23 in 2018

1. 10th Montpellier Summer School, 2-6th July 2018 - MONTPELLIER, FRANCE

Anniversary celebrations include bioglasses

This year marked the 10th Anniversary of the ICG Summer Schools in Montpellier, France. The lectures were held in our normal venue at the University of Montpellier, but the surroundings were unrecognisable because of extensive building work throughout much of the campus. Finding a route from the University accommodation to the lecture rooms on the first morning was far from straightforward even for old timers on the course and to add to the confusion it changed throughout the day to allow for the movement of heavy building equipment across the site. Fortunately, Prof Hehlen turned up on time to guide participants through the maze of fencing. A few though arrived late for the school because of transport upheavals the previous day in Paris following strike action; sadly, they were delayed for a second time by the building work.

The first day was run as a single session for both the basic science stream and for those who had come to learn about bio and pharma glasses. 40 students were present, of whom a quarter where primarily registered for the bio stream. The temperatures outside were high, around 33C for most of the week, but powerful air conditioning inside the lecture rooms kept everyone awake. In the afternoon the students were each allocated a 3-minute slot to introduce themselves and explain their research interests. They showed admirable time-keeping skills and we were able to start the last lecture of the day on time. This talk given by Prof Delia Brauer gave everyone the opportunity to learn of the latest research in biomaterials. A welcome reception followed.

Over the next three days the class divided into two groups following the traditional Glass Science courses used for the previous 9 years and a stream on biomaterials that included the use of glasses to repair body parts, such as teeth and bones and was followed by an in-depth discussion of the design of glass containers for specialist products in the pharmaceutical industry. The chemical durability of glasses formed an important theme carried over from the first day into these specialist lectures.

Projects were allocated on the second afternoon to the students in groups of five, with the deliberate aim of mixing people with different backgrounds and expertise. For one hour on each of Wednesday and Thursday afternoons small group tutorials were held to explore topics introduced earlier in greater depth and more interactively. The tutorials proved particularly popular this year and there was significant demand for more such interactive sessions and slightly fewer formal lectures.

On the final morning everyone came together again for topics that introduced the applications of science in an industrial context. These helped to indicate the kinds of career paths that might be available. Unfortunately, one speaker had been taken ill overnight but this provided an opportunity to distribute copies of the text book created over the previous 8 months in celebration of our Anniversary. Each participant was given one and there was considerable enthusiasm from the students to collect the signatures of the authors present.

In the afternoon the students took the floor to present the conclusions of their project work. Eight groups spoke on topics that covered a wide range of subjects. The winning group, consisting of Petr Chrast, Susanta Sengupta, Julia Weiβhuhn, Bulat Sydykov and Marcela Arango Ospina; their topic was: ‘Is it accurate to describe the silica rich exoskeleton of certain deep-sea creatures as glassy? Can an understanding of the way biological processes naturally produce complex structures based on glassy materials help us to develop new materials?’ Before the awards were announced the party atmosphere to celebrate our 10th Anniversary began. Profs Conradt and Parker played two piano duets as part of the entertainment and one of the students had brought with him a banjo which he used to lead some community singing.

During this session we were joined by a group from Wuhan University who wanted to see how the Montpellier Schools compared with the more recently developed Winter Schools in Wuhan. A representative of Prof Peng Shou, Prof Pan also gave a talk on the Chinese Glass Industry to conclude the morning session.

At the end of the day we had our end of school party at our normal venue of Trinque Fougasse, a short distance away. Here glasses and stomachs were filled frequently with wine and plates of Tapas style food. Conversation too flowed until late into the evening until we finally parted until the same time again next year.

Next year’s summer school will be from 8-12th July again in Montpellier and before that we have a Winter School in Wuhan (5-9th November 2018). More information about both is on the ICG Web site (

Finally, we wish to thank our speakers all of whom give their time without payment; the course could not run without their contribution. The speakers on the Basic Science course were in order of presentation: J Parker, R Conradt, D Brauer, R Vacher, P Florian, H Inoue, J Deubener, J C Sangleboeuf, A Takada, B Hehlen, M Choudhary, R Hand, K Bange, Prof Pan, and on the Biomaterials options: R Hill, L Hupa, A Boccaccini, M Guglielmi and D Zuccato.

Book launch at the 10th Anniversary ICG Summer School in Montpellier

The ICG, a platform for global cooperation in the world of glass, has as part of its mission the promotion and stimulation of understanding and interaction between glass experts in science and technology, art, history and education. To revitalize the role that education plays a committee was created, using a European Grant, to support and develop teaching programs on glass fundamentals in 2005. The target audience was those new to the subject, whether in industry or academia, groups perceived as the lifeblood of research and development and the key to the ongoing success of the material in the marketplace. Based on this background, the first ICG summer school took place in Montpellier in 2009. It has been repeated annually ever since and at the 2017 school everyone agreed that 2018 should be a celebratory event. One aim was to prepare a book which summarized the course content but which also captured the historical development and the philosophy of the schools, explaining the lessons learned and offering a framework for others wishing to follow.

Preparation and publication were completed to coincide with the 10th School in July 2018 and to high standard using full colour. The early chapters review the history and the evolutionary processes involved in creating the school’s present structure. The major part of the book presents the core of the course – spanning glass science lectures on: structural analysis using the latest analytical techniques and atomistic simulation; optical, chemical and mechanical properties; thermodynamics and transport phenomena; and phase separation, glass ceramics and glass surfaces. Over the last five years technical streams on: glass melting technology; glass production; glass surfaces and thin films; and numerical modeling, have run alongside the more fundamental courses. The chapters are written in a tutorial style by the lecturers – all recognized glass scientists and technologists. The appendices include more personal and less formal descriptions of each event, an example of questionnaire responses from the students, biographies of the contributors and last, but not least an index.

The book provides an invaluable introduction to those starting a career in glass. It offers a starting point for the next generation of glass experts who will in turn be able to influence the health of academic glass research and stimulate an efficient and productive glass industry in the face of global concerns such as sustainability, global warming, health issues, energy shortages and population growth. The International Commission of Glass appreciates from the success of these schools that this future is in good hands.

A key feature of the courses is to encourage networking, links that can and do continue well beyond the close of each school. While a book such as this encapsulates what is taught, the only way to experience the value of the contacts made between all the participants, whether teachers or students, is to participate. The dates of future schools and how to join can be found on the ICG web site (

3. 4th ICG Winter School, Wuhan, China, 4th-8th November 2018

4th School is the largest to date

The fourth ICG Winter School at the Wuhan University of Technology in China began on Sunday 4th November 2018 with registration in the ornate and spacious entrance lobby of the Vienna International Hotel. The day marked a transition from warm autumnal weather to colder wetter conditions which perhaps better suited our planned indoor activity.

The Opening Ceremony started at 8am on Monday and needed a large lecture theatre at the Conference Centre on the Mafangshan Campus of the University. We were warmly welcomed by Prof Zuyuan Liu, the vice president of the University. These words of welcome were echoed by the ICG president Prof Alicia Durán and immediate past president Prof Manoj Choudhary who together warmly welcomed the 57 or so student participants in the audience along with the 16 international lecturers giving the course. Prof Shou Peng, a past ICG president who has strongly supported the creation of the ICG schools in China was unfortunately unable to attend and sent his apologies. Prof Parker outlined the activities that ICG undertakes for the glass community and introduced the students to the school’s format, explaining the importance of getting involved to maximise the benefits available, using a quiz to illustrate the need to process and analyse the information provided.

Finally, those students who had received grants to travel from beyond Asia to the event, 6 in total all from Europe, were presented with their awards. At the end of the school one of the visiting students explained what being able to attend had meant, ‘The school has let me bounce ideas with worldwide experts, and experience China for the first time. A world powerhouse where research is concerned. Massive thanks to organisers and Chinese students.’

This innovation supported by Prof Shou Peng had a second unexpected and very positive consequence, which was the resulting interactions between students from different cultures. On the questionnaire responses, almost every student without prompting highlighted this as a key benefit of the course. Because the European students were separated for the project work everyone had to work hard at communicating and this certainly gave the Chinese more confidence to use their existing language skills, helping to overcome the challenges of running a course in English. A Chinese student wrote, ‘I had a great time these days. I will never forget nice foreign professor, so kind and perfect. Great foreign students – so kind too. This is greatest day.’

After a group photograph, everyone was straight down to work with three lectures, before lunch. two on basic glass science, given by Profs Alicia Durán and John Parker, and a third presented by Prof Russell Hand introduced this year’s conference theme on ‘Glass for Nuclear Waste Immobilisation’. It was the students turn to speak in the afternoon, each giving a 10-minute presentation explaining their backgrounds and interests. This information was used in assigning project work and served to initiate networking. The afternoon session was closed by Prof Manoj Choudhary who talked on heat transfer in glass making.

For the next two days the school had two parallel sessions on 1) Glass formation, structure and properties and 2) Glasses for nuclear waste immobilisation. 22 students had registered for the first option and 16 for the second, but numbers for the nuclear option were boosted by 15 or so attendees from industry. Lecturers on the first stream were: Prof Reinhard Conradt, Prof Yuanzheng Yue, Prof John Parker, Prof Rene Vacher, Prof Bernard Hehlen, Prof Jinjun Ren, Prof Tars Kavetskyy, Prof Akira Takada, Prof Manoj Choudhary and Prof Michael Ojovan. The teaching on nuclear waste immobilisation was based on members of ICG’s technical committee TC05 on Waste Vitrification (Prof Michael Ojovan, Dr Oliver Pinet, Dr Kevin Fox, Dr Hong Li, Prof Russell Hand, Mr Kevin Selkregg, Mr Wei Zhang, Dr Mingzhou Chen and Dr Richard Pokorny). The two streams recombined for the last two days of the school which concentrated on thermodynamic calculations and Raman spectroscopy together with the presentations by the students of their project work.

There was a lively social side to the whole event to encourage networking. Coffee breaks were well provisioned with a variety of fresh fruit and cookies and conversation flowed. One of the responses to the end of school questionnaire confirmed that the students really welcomed the approachability of the lecturers on the course. On the Monday evening students and lecturers joined together for a sit-down meal at a Welcome Reception and again on the Thursday a Banquet was organised at a nearby restaurant. Each student attending the school had been given a copy of the ‘Teaching Glass Better’ textbook recently published by ICG and the welcome reception provided an opportunity for students to have their copies signed.

A feature of all ICG schools is the involvement of students actively in the learning process. One of the lecturers who had not participated before commented after the event, ‘I am also impressed with how you included the students in the program’. One way of encouraging involvement was to stimulate the asking of questions. Anyone who asked a question was given a stamp on their notebook. The winning student achieved 6 questions and received a small prize on the last day. A new feature of the Science thread was a tutorial session based on written questions by the students submitted during the week. This gave the attendees the opportunity to apply the course content to their individual projects and the practical problems they were experiencing. The Nuclear stream adopted an alternative approach by running an extended round table discussion at the end of the last day of their thread.

The main activity though was the project work. Altogether the students were split into 8 groups with 4 or 5 in each team. The projects were very open ended to give them flexibility in creating a solution. Presentations were made on the last day, each group then had to answer searching questions posed by those present. Once all the presentations had been given the staff left the room to judge and rank what they had heard. Meanwhile the students themselves had to fill in a questionnaire on the course itself and they also formally received their certificates of attendance. In a brief ceremony Prof Alicia Durán was appointed as a Guest Professor of Wuhan University of Technology and finally it came to the announcement of the winning teams. Prof Reinhard Conradt as the chair of the group of teachers firstly congratulated everyone on an excellent set of presentations. Then he announced the outcome of the panel’s deliberations. Third prize went to a group from the Nuclear theme. ‘You are members of ICG Technical Committee TC05. Design a round robin study to compare the long-term stability of different vitreous waste-forms.’ Second and first prizes went to groups from the Basic Science thread. ‘The ICG wishes to apply to the United Nations to devote one year to celebrate the ‘Glass Age’. What do you think are the 5 most important contributions that glass makes to modern life? Explain your decision.’ The winning team consisting of: Baochen Ma, Linfeng Ding, Zheng Zhang and Congyun Li and worked on the programme ‘Select the 3 best ways in which glass can help to reduce the CO2 levels in the atmosphere. Indicate the magnitude of the reductions that are possible.’ It also was announced that the fifth ICG winter school will be held on Oct. 20th – 26th, 2019, at Wuhan University of Technology.

On the last afternoon, those staff and students remaining in Wuhan were given a tour of the Wuhan department followed by a trip to the East lake, the biggest in-city lake in China. Amazingly after a week of rain and just as we were leaving the warm autumnal weather returned and we were able to walk around the shores in bright sunshine. The long trip home allowed an examination of the questionnaires and it was clear that everyone had really enjoyed both the course content and the excellent standard of organisation of the event. This same reaction has been repeated many times since by those responsible for the teaching.

4. Youth Outreach 2018 activities

The ICG Youth Outreach Team is composed by:

Delia Brauer (DE)
Tunc Goruney (TK)
Mathieu Hubert (US)
Julian Jones (UK)
Erik Muijsenberg (CZ)
Randy Youngman (US)

A Youth Outreach event was organized during the ICG conference in Yokohama. The event was well broadcasted prior to the event (efforts from Satoru Tomeno are to be recognized). With over 200 registered participants indicating that they would like take part, the event had to be split over 3 days to allow for everyone to participate. On the 1st day, the focus was put on networking in academia (mentors mainly from universities), while the 2nd day was mainly focused on mentors from the industrial world. The 3rd day was a mix of academic and industrial mentors.

Every day, a brief introduction of the event and its brief history of ICG Youth Outreach (Istanbul 2017, and now the 2nd edition) was given, highlighting the importance of networking. A brief presentation was given, before leaving the room to free discussions between the participants. Tables were arranged both inside and outside the room where the event took place, and all the students, young professionals and mentors participating were given a lunchbox and a table number, so they could gather, network and share their experience.

For the 3 days, the program was as follow:

Monday: brief presentations by Manoj Choudhary and Alicia Duran on the importance of youth outreach to the ICG, and few tips to network. Networking with focus on mentors from the academic side

Tuesday: brief presentations by Mathieu Hubert about his career and tips on networking, TCs and benefits of participation to ICG. Networking with focus on mentors from the industry side

Wednesday: brief presentations by Erik Muijsenberg about his career and tips on networking, ICG activities and benefits of participating to ICG. Networking with mentors from both industry and academia

Overall, the event was a great success, with very positive feedbacks from the participants. The first day gathered around 80 people, the 2nd and 3rd over 60 each.

Preparation of a document summarizing recommendations/guidelines for the organization of youth outreach events, to be passed along to the ICG conference/seminar organizing committees

Provide support to the organizing committee of the ICG 2018 seminar Yokohama for the Youth Outreach event planned there

Work on a webpage/website dedicated to Youth Outreach activities and events

Continue working with ICG to propose strategies that could be implemented to attract, recruit, and retain young glass science and technology (and related disciplines) professionals.

5. Activities in Brazil

2nd Glass Technology Course by CeRTEV, São Carlos, Brazil, August, 20-25th, 2018

As part of the activities of the Technical Committee "Glass Education" TC 23 of the International Commission on Glass (ICG), the CeRTEV, Center for Research, Technology and Education in Vitreous Materials, founded by Fapesp, the São Paulo State Research Foundation, Brazil, has organized the second Glass Technology Course, for glass industry personnel and engineers.

The CeRTEV Course in Glass Technology was held at the Vitreous Materials Laboratory, LaMaV, Department of Materials Engineering, Federal University of São Carlos

For six days, 33 lectures were presented by ten professors, academics, consultants and glassware specialists, who approached, in addition to themes including basic notions of glass structure and properties, also the glass processing, shaping as well as glass transformation.

The course also included two technical visits: the first one to a sand deposit that also deals with sand treatment, and the second one to a glass industry, an automatic processing plant for glass packaging production. At LaMaV, there was an experimental demonstration of a laboratory glass melting, manual fiber pulling, the production of Prince Rupert drop, glass crystallization, visual (under polarized light) thermal stress evaluation before and after glass annealing. All those practical lessons illustrated several subjects discussed during the lectures

The course was joined by twelve attendants, most of them engineering from seven different glass industries and transformer, as well as two attendants from academy.

According to the attendant’s evaluation, the course was successful, provided very rich discussions including real problems experienced by the students in their respective companies

A technical course of glass production – teacher training

The course "Techniques in Glass Production", a project in partnership with the Paula Souza Center, Abividro and the glass company Nadir Figueiredo, started with its first cohort. 40 students were selected among ~160 applicants in a public selection procedure. At present date, December 2018, students have already completed their second semester and they will complete their whole training in July 2019, at the end of their third semester.

CeRTEV has closely followed the course and offered several training sessions to the teachers of the Paula Souza Center involved in the course, namely:

Teacher training – melting glass at LaMaV- Vitreous Materials Laboratory from UFSCar- Federal University of São Carlos, Brazil, for the technical course on glass Production

Other plans and activities

Envisaged TC23 activities for 2019

So far, the envisaged activities comprise the support and continuation of ICG schools.

Some recommendations for the organization of successful ICG schools were proposed in 2016, and exposed once again here, to stress the importance of the subject.

  • A successful school should address, beside an annual focus on selected special topics, four core topics. It is felt that the new generation of glass scientists needs a solid foundation in
  • fundamentals of the glassy state,
  • structure of glass
  • thermodynamics of glass,
  • transport properties, comprising both materials science (diffusion, electric con­duction, and crystallization) and engineering (heat and mass transfer).
  • Instructors should not offer “conference type” talks illustrating their latest scientific achievements. Rather, the lectures should provide good summaries of what students need to know.
  • If possible, should be kept in the geographical area where they started.
  • Students activities (projects) and student-teacher interaction are major ingredients of a successful school.
  • Planting new schools in new geographical areas is not a focus of the TC23. Such initiatives shall, however, be supported by providing advice. A need is felt to define rules under which conditions a school may run under the ICG label.

The Montpellier Summer School 2019 will be the 11th event in a row. In 2019 the main streams will be: Glass Formation, Structure, and Properties and Hazardous Waste Vitrification

The 5th ICG Winter School is planned for 20th-25th October 2019, Wuhan, China, with the topics: Glass Formation, Structure, Properties

In 2019, ICG will also sponsor the North American Summer School on Photonic Materials (NASSPM) at Laval University in Quebec City, to be held the week immediately after the ICG/GOMD meeting in Boston (

A third CeRTEV Glass Technology course is also planned to be held in São Carlos, Brazil, in August 2019.
