How could you age a recently hard silver soldered joint in copper so that it blends in to the old copper and does not look like a new joint?

Copper sulphate.
I don't know, but some of the videos by this chap may answer the question:

Indeed. I love the workbench with catcher tray underneath!
Certainly a master of the "dremel"!
I suspect if your "sawdust" was as expensive as his, you would want to catch it as well :-)
Indeed.
Use some HP brown sauce to clean up the rest of the old pipe to match the repair, which presumably was cleaned with flux before brazing ?.
Paint it with tinted lacquer? Brian
Would that not etch it? Brian
Polish up the old pipe? ;-)
And there was I thinking this was a thread about old policemen. Brian
Many years ago I used to make terrariums as a hobby using copper tape on the edges of the glass pieces. These were then soldered together, and to blend the solder with the copper tape I always used a solution of copper sulphate. This had the efect of colouring the solder so that it matched the copper tape. It worked very well.
PC 49 came to mind
Factories making cigarettes have very efficient extraction equipment. On the basis that the dust contains some tobacco they weigh it and claim back the tax
Makes sense - much like pubs collecting spoilt beer and sending it back to the brewer to let them dispose of it in front of the excise officer!
There are lots of incidences where it has been resold as an expensive item. :-)
There is loads of it and it is old and I would rather it not look like it was added to.
