Protecting Copper Patina

Hi there. I was rooting through my little treasure bin and I found a little bottle of something blue that had purchased from a jewelry supply store during a going-out-of-business sale. It was cheap, sounded promising, so I bought it. Just now trying it. It appears to be some kind of verdigris (not that I really know what that means), as when rubbed on copper, a beautiful bluish green oxidation of sorts will appear, then dry very chalky and fragile. It is easily wiped off with just a finger. Too bad. I love the color. Is there a recommended way to either seal this (without a thick, unseemly coating on the work) or create a more durable, similar finish?
The bottle says something about "for mokume" - it's a name "Johnson's" or something. I'll dig it out and relate the name tomorrow if it makes a difference to anyone.
