I delacquered my horn about a month ago. Now, I'm not expecting it to all the sudden, change into a patina color, nor do I think it takes only a couple months. But I really love Wynton's trumpet, and would like it to look similar, it's just a perfect color (and horn!lol). I tried google, and came up with lots of jewlery forums, but they use chemicals on their brass! I'd hate to add more chemicals to my horn than what has already been done. I'm actually looking for a natural way. I also read that they use: Buttermilk or urine. Yes, urine! I haven't tried the urine yet, and francly I don't think I will!lol The Buttermilk didn't seem to do much. But I also tried lemon juice (just as an experiment, but nothing happened. Any thought/ideas???
