In museums, crystals have been reported in few cases, from 2006 with thanks to the Rijksmuseum (Amsterdam) and the Museum of Fine Arts (Boston). After analysis, the Rijksmuseum and the MFA found the same pollutant compound. We found something different. And you, do you have crystals issue ? Please contact us to share with HCC team.

There's the usual difficulty with exposure of ivory to moisture, but poultices/gels as a delivery method might be a way to control the amount of moisture being introduced?

They were damaged in a leak, and the dye from the case was transferred onto the ivory. We have managed to remove some of the dye but it is still pretty obvious. We have tried humidifying, IDA and WA paste, but it has not removed the dye. I was hopping that someone may have more experience and ideas into what could be done to remove the dye.

Conversations with Changemakers 04/04: Leading Energy Consumption Reductions at the Statens Museum for Kunst (SMK) and the Kunstsammlung Nordrhein-Westfalen Message: Hello! The Sustainability Committee would like to invite you to our next Conversation with Changemakers! Join us on Friday, April 4 at 12noonEDT for the tenth in a series of webinars where AIC's Sustainability Committee chats with conservators and allied professionals who are implementing changes to reduce the energy consumption of buildings that house collections. Pil Rasmussen, Director of Conservation at the SMK – National Gallery of Denmark in Copenhagen, and Nina Quabeck, Head of Conservation at the Kunstsammlung Nordrhein-Westfalen in Dusseldorf, will discuss steps they've taken at their respective institutions to spearhead the reduction of greenhouse gas emissions via HVAC shutdowns, environmental parameter expansions, and other energy efficient solutions. Case studies will also touch on how these changes have led to a paradigm shift toward more equitable lending practices. The energy used to heat, cool, de/humidify, and light buildings is the biggest environmental impact of the cultural heritage sector. After decades of regarding one-size-fits-all, non-fluctuating indoor environmental parameters as the gold standard, the field is now questioning the value of this approach. As the recent extreme weather and the associated risks to cultural heritage continue to remind us, the need for change is urgent.

Heritage Conservation: Protecting the places and traditions that communities care about most. Social Justice: Working with communities to build a more welcoming and just society. In 2025, the Fund will award up to 10 Prizes, each including $150,000 in unrestricted funding over three years, plus $25,000 for technical assistance. Awardees also have access to a dynamic peer community, strategic resources, and hands-on support to help turn their ideas into sustainable growth and impact.

At this point, I'm starting with looking for new homes and users for the following: Technical Studies in the Field of Fine Arts, published by the Fogg Art Museum: Volume III, 1934 - 1935, hardcover Volume V, #1 July 1936; #2 October 1936; #4 April 1937 Volume VII, #2 October 1938 Volume VII: #1 July 1939; #3 January 1940 Studies in Conservation, IIC: random volumes from 1959 through 1975 Mostly full series from 1977 through 2023 JAIC: mostly full series from 1997 through 2023 Conservation and Conservation Perspectives, the GCI Newsletter: mostly all volumes from 1991 to date. I realize that many of the more recent materials may be available online, but earlier volumes may not be. I would love to donate them to an under-resourced organization or to practitioners that are working to rebuild their libraries after a fire or flood or some other loss. All are free, but am asking that whoever wants them pay for shipping. Wendy Jessup Arlington, VA ------------------------------ Wendy Jessup Conservator Wendy Jessup and Associates, Inc.

I use a special hand cleaner called Reduran which removes the dye stain from my skin as if magic. I'm not sure if it would be suitable for ivory however. I'm a wooden objects conservator and know very little about ivory. Reduran was re-named a few years ago to Kresto Kolor Special. Sadly it was discontinued by the manufacturer/distributor here in the States, but I suspect that it might still be available in UK or Europe as it seems like a European product. If you do find it over there, let me know as my supply is running low and there is no replacement. There is an entirely different product called Amodex and it is marketed to people who use fountain pens . . . sooner or later fountain pen users get ink on their clothes. You might consider looking into this product as well.
