I think that the Pot looks normal for having been in your furnace for a year. I would expect that it is simply time to change the pot, which I consider a normal (if not frustrating) cost of doing business. I am guessing that your small bubbles are coming from melting at far too low of a temperature and/or the difficulty in fining out cullet.
