    Hi, Linda, 

    It's unlikely that your solution is spent aleady. Yes, temperature
    makes a difference, but nitric should work fine even cool, and will
    still work after it turns a pretty intense blue. Could there have
    been any kind of residue on your silver last time? My favorite
    solvent for after etching is laquer thinner-- it is a mixture of
    solvents, and will dissolve almost anything. 

--Noel
