 This is Richard Rogers, who is a metals conservator. He's done some fabulous work for us with our astrolabe, which is going online to the Metropolitan in New York. So what have you done with the astrolabe? Well, we've generally cleaned it. As you know, there was a number on the back, which we identified the number, which we removed from there as a bit of disfiguring and put onto the bottom edge so it's a bit more discreet. And then there was some third-degree corrosion around the main ring there, which we cleaned off and treated. And also the black that was in the depth of the detail there, which was hiding the nice sort of scroll design going round the edge. Looks so nice. And then there's just a wax to sort of present it better and remove the blocks of paint that were round the edge. I think what's lovely about it is it looks like it's had some conservation of something, but it doesn't look overly clean. So it looks like an object. Yeah, I've kept it. Where its edges sort of didn't really work. Yeah, we haven't tried to posit it or anything like that. That's fabulous. Thank you for that. Okay, thank you.
