If this is the case, they could be safe to use. Perhaps others are more familiar with these, but I don't think you have to discard the idea outright. Hope this is helpful.

Our Exhibitions department is very keen on a wood veneer deck within a case. If anyone has knowledge of this product and insight into their use within cases and with collection material, I would love to chat. Please feel free to email me: [email protected] <[email protected]> Thank you! ------------------------------ Kate Fugett Preventive Conservator National September 11 Memorial & Museum Co-Chair, AIC Sustainability Committee ------------------------------ 2.From: Hildegard Homburger Posted: Wednesday May 14, 2025 9:08 AM Subject: Course on Photoreproductions: Identification and Conservation Message: Course: Photoreproductions: Identification and Conservation Berlin, Germany, 16.-17. October 2025 https://hildegard-homburger.de/lichtpausverfahren.html In the course the major photoreproduction processes, (Cyanotype, Vandyke print, Ferrogallic print, Diazotype, Silver gelatine contact print, Gel lithography, Negrography), will be explained historically and technically. The two days provide an opportunity to look at a great number and variety of original copies under magnification and to exercise the identification of their techniques. A separate part will focus on the conservation (storage, exhibition and treatment) of these different photoreproductions. The language of the courses will be English. Maximum participants: 8 Costs: 390 Euro or 350 Euro for IADA-members Registration requests should be sent to h.homburger(at)t-online.de Hildegard Homburger Papierrestaurierung www.hildegard-homburger.de <http://www.hildegard-homburger.de> ------------------------------ Hildegard Homburger Private Paper Conservator Berlin Germany ------------------------------ 3.From: Anna Whitehead Posted: Wednesday May 14, 2025 5:39 PM Subject: De-acidification using calcium bicarbonate Message: Hello colleagues, I am looking into ways that a paper conservation lab would produce calcium bicarbonate solution. Please could anyone doing this share the methodology for setting this up in the lab; what equipment you use and how it is all put together. It would be helpful to have as much detail as possible. For example, the brand of fish tank pump and fish tank gas diffuser, just to get a picture of what is needed and to get some idea of cost to implement. Feel free to email me directly. Many thanks in advance.
