Hello everyone, I'm Laura Couturier, a conservator of Object and furniture. In the next minutes we're going to discover the conservation of this radio, which is a receiver belonging to the Museum of Social and Human History in Surin, France. This work resumes my family and master's thesis at the National Institute of Heritage. Emma Adde and François Duboissez supervised it, Marie-Pierre de Guille, over-stores the historical study, and Emily Le Bour, follow with the scientific research. First, we need to forget about our time and come back at the beginning of the 20th century, when Philips designed the radio receiver and La Rato Technique manufacturated in 1935. So, this radio receiver is a case built on two feet. Its face has paces for set of buttons. A backlit frame contains a textile where the sound worth emerging, and a station deal made of siloed. Sides and case-top doesn't have anything added. The back is open and revealed the modified electronic section. The radio has alterations and must be treated. First, I took about the radio and conservation measures start with testing. I makely remove corrosion. After, I apply micro-raster line wax as protection for metal. I stabilise the fray at textile with gluesil-j. Father Brock and plywood, to begin, the material required moisture supply with an abalyzer. I fasten it with fresh glue and apply it into the press. After 30 minutes, I cleaned it and I could back everything into the press. I solidify the uplifted veneer and wood with a fresh glue. I fix it the lighting lamp with an use grue. And finally, I must consolidate the broken cellulote. But first, we must find a glue adapted to it. After preliminary experiments, we selected 3 resin, Everart, Acryl 33 and Cluesil-j. We realised that a simple drop-by-drop consolidation isn't enough. Then we decided to use adhesive film which I made by pulling liquid resin across the surface. And glued paper that I made by applying a Japanese paper on the fresh adhesive film. We determined the transparency and colour with chlorometric dust. Only adhesive films of Everart's Acryl 33 and Cluesil-j had good results. We evaluated the stickiness properties with a tan-slee dust and a peel dust. Adesive film of Everart's and Acryl 33 are the best results. Next, others experiments validated their reversibility. After building articles, we learnt that Everart has an acceptable pH after AG, while Acryl 33 haven't. Then we selected Everart. We could consolidate cellulote with it. The first step, I used it on putting the two pieces on the same level with wedges and weights. Then, I infiltrated Everart's in Breck and Cracks. It dried one hour and I removed wedges and weights. Next, I cut Everart's films into thin ribbons. I put them on the Breck and I reactivated them with human. For the paper's consolidation, we decided to use adhesive film of Everart. I applied them to tear and uplift and I reactivated them with a hot spatula. Consolidations was done. Then, we started treatments for a better reactivity with a adapted cleaning. After, I filled the varnish lacuna with regalores diluted in lagrarian. And came the retouching. I applied black watercolor to paint gap and when it was dry, I put regalores. I also applied it to backlit scratches. I finally reassembled the radio. And we are now able to see the before and after picture. The receiver is table and we gain intelligibility while keeping traces of utilization and handling. Thank you for your attention. And if you have any questions, feel free to contact me.
