Where so little heat is involved, silver brazing may not have truly been needed, though the added strength may have been what you were after.

In any event that "cascade" should prove a wonderful visual delight and definitely makes for a stunning static piece as well!

Super job on that one Jim, your artistic/engineering talents know no bounds!!!

Clean and polish it to the level that you like and then rinse it in acetone and spray a coat of clear lacquer over it and it will greatly reduce the tarnishing!!!

There was no way that soft soldering was going to hold this together with any strength on the minimal contact parts that are touching, then I needed to soft solder the spouts in and then everything would have let go. You couldn't break it apart now if you tried.
Silver brazing is easy with a good torch and a good hearth, stacking those pieces upside down to get it setup just right sure wasn't easy.

I am tempted as I'm a big proponent of clear coat, both normal and high temp. Though when it eventually breaks down you've got a big job on your hands using paint stripper to get it off.
