Thank you!! I’m glad you cleared that up!! I was t going to do anything until I knew for sure what to use. I knew not to use any cleaners or things like that. I just want to preserve it. I also didn’t know once the crazing starts, there’s no way to fix it DIY. But it makes perfect sense- cracks are cracks, no type of water or liquid is going to repair that. When you said, “dried out”, my first thought was to add moisture back to replace it. But it’s not a raisin and isn’t going to plump back up lol. Very helpful info you have given me and I really appreciate it. I don’t know how expensive it would be to have Opticon put on it, but right now, I’m afraid to let anyone touch it. I’ve only worn it once and was super careful. Worth anything or not, I think it’s beautiful and I’ve never seen anything like it. I’d love for this to be a family heirloom. Thank you so much!
