»The trustees, staff and members of ICON are devastated by the events unfolding in Ukraine and by the terrible suffering of the people and the sad loss of civilian lives. Although our primary care is for the safety and wellbeing of the people of Ukraine, we remain concerned about the continuing threat to the tangible and intangible cultural heritage of Ukraine.«*

Deffner & Johann was contacted by Prof. Dr. Alexandra Jeberien, THW Berlin, asking for equipment and materials urgently needed to pack cultural heritage in Ukraine safely.

For the first time, IADA is inviting to a virtual symposium of "International Association of Book and Paper Conservators" from 14 to 17 February 2022, taking place this year with the motto "SHOW IT AND SAVE IT - Exploring the Compromises between Exhibition and Preservation".
IADA uses the opportunities and possibilities of this IADA 2022 virtual conference in a very innovative way and offers a comprehensive daily programme with exciting contributions and impulses on all aspects of paper restoration and conservation.

For many years, Deffner & Johann has presented products and restoration solutions at the global IADA conferences. We are excited to sponsor the IADA Virtual Symposium again this time.

As an internationally operating specialist dealer for materials, tools and equipment for restoration, conservation, archiving, depot and transport, Deffner & Johann had set itself the goal of presenting visitors to the tenth Exponatec Cologne, not only a representative overview of proven and new products from its product range, but also a platform for exchange.

We are pleased that we can once again offer our customers Cyclododecane for their applications in restoration, monument conservation and archaeology.

On the occasion of the 80th birthday of the long-time owner and managing director, Deffner & Johann is launching an exceptional brush series: "Meisterklasse Edition Harald Johann".

Dear customers

We would have very much enjoyed celebrating our anniversary with you at denkmal 2020, because 140 years would have been a great occasion. As you know, things turned out differently and all trade fairs and conferences had to be cancelled. We would therefore be happy to present some of the things we would have liked to show you in Leipzig: a selection of the latest innovations, D&J infographics, as well as the familiar and the tried-and-tested.

We appreciate your interest and will be happy to answer any questions you may have.

Your Ralph-Uwe Johann & Team

The new MS3 is the successor to MS2A and was developed by CSIRO (Commonwealth Scientific and Industrial Research Organization) in collaboration with leading museums in Australia and Europe. Carl Villis, Senior Conservator of Paintings at the National Gallery of Victoria (NGV) comments: "MS3 is clearer and more consistent in its appearance than the earlier resin as a direct result of the flow chemistry process employed by CSIRO's scientists."
